1. CROWN II TECHNOLOGY
Crown II is a printer document-processing technology that provides advanced multitasking
and networking capabilities across a full range of print systems. Crown II technology takes
advantage of multitasking to receive, interpret, and process multiple documents while another
document is printing. Crown II printer technology is divided into four major segments:
Spooling
Interpretation
Rasterization
Printing
The illustration shows the internal structure of the Crown II printer. In this chapter we discuss
the function of these segments.
A serial interface may be an option. Refer to your Crown II printer documentation for
the actual interfaces available.
2 Part 1 Crown Book
CROWN II CONFIGURATION
Direct communication with a Crown II printer is
possible by means of the control panel menu.
To get an overall impression, the illustration
shows an example menu for a Crown II printer.
Crown II printers build the control panel menu
dynamically at power on time, according to the
configuration (model, options installed, etc.).
This means that your Crown II printer may not
show all the menus discussed here.
Refer to your Crown II printer
documentation for the actual configuration
menu.
There are three main menus:
1. Installation (or Security) Menu—Use this
menu to protect printer settings by means of
passwords (security). If passwords were
assigned, you may access the Operator
Control and/or Administration menu only
after entering the correct password(s).
Accessing the Installation Menu may require the use of an optional security key.
2. Operator Control Menu—Use this menu to select default document processing options
such as the copy count, input and output media bins, chain input bins, and duplex (if a
duplex unit is available and installed). The submenus of the Operator Control menu may
vary according to the specifications of the particular Crown II printer.
3. Administration Menu—Use this menu to configure default settings for printer
emulations and printer interfaces, configure special pages, calibrate the print engine, and
configure hard disks (if installed).

CROWN II FIRMWARE
Crown II Operating System software resides inside the Crown II
printer and is referred to as printer firmware. The Crown II
firmware is stored either in flash ROM or on the internal hard
disk.
Flash ROM is nonvolatile memory. When the power is
switched off, this kind of memory holds the data previously
stored.
Updating new Crown II firmware is performed via one of its
interfaces. The illustration shows an example using a PC
connected to a Crown II printer by means of an interface. The
Crown II firmware is downloaded to the printer. The printer
recognizes the nature of the code and replaces the older
firmware with the new one that is downloaded. After
downloading, the printer restarts with the new firmware resident and active.
When your Crown II printer is switched on, by default it prints a startup page. This page is
generated internally by the Crown II Operating System. Below is a list of the Crown II
information pages that may be printed by the Crown II Operating System.
CROWN II
INFORMATION PAGES
REMARK(S)
Startup
Each time your Crown II printer is switched on, it prints a
startup page. This is particularly important to verify the
functionality of your printer and installed options.
You may disable printing a startup page by means of the
control panel.
Status
There are two kinds of status pages:
Standard: A one-page overview of the most common printer
settings. This page shows the current Crown II Operating
System, the memory configurations and the CrownNet
network firmware version installed.
Advanced: The Advanced Status Page gives information
about printer parameter settings, fonts, and emulations
available. The document may have many pages, depending on
the fonts installed.
Statistics Page
This page gives statistical information about the usage of the
printer and the current status of the consumables.
MEMORY
4 Part 1 Crown Book
Network Configuration
The network configuration page gives full information of the
network interface setup. Up to two network interfaces may be
installed (one is standard and one is optional) in a Crown II
Print System and each network interface has its own network
configuration page.
Registration
(Color printers only)
This page shows the registration of the four colors of a Crown
II color printer in respect to each other.
Calibration
This page is used to verify the adjustment for the amount of
toner (density) of the engine for calibration purposes.
CMM Profile
(Color printers only)
CMM (Color Management Module) This page gives
information about all ICC profiles and color device links.
Header
A header page is a job separator page that can be enabled to
print prior to a print job. It may give information about the
printer language, the user, the document name, the interface,
and the start print time. It is possible to specify the media bin
for the header page, so you may use a different media type
than is used for the rest of the print job.
Trailer
A trailer page is similar to a header page, but it prints after a
print job and gives information, such as total number of pages
in the print job (including a header page but excluding the
trailer page) and how long the job took to print. Also the
media bin for this page can be specified, as with the header
page.
Crown Book Part 1 5
SPOOLING
Each active Crown II printer interface has an
exclusive input buffer. The size of the input
buffer needed should be dictated by the nature
of that interface. An Ethernet network interface
may receive data at a high speed and, therefore,
may need a large input buffer. A serial interface,
however, is a relatively slow interface and may
not require a large input buffer.
A serial interface may be an option. Refer
to your Crown II printer documentation for
the actual interfaces available.
The Simultaneous Interface Operation (SIO)
takes the print data from each active interface
simultaneously and stores it in the host input
buffer. The host input buffer functions as a
temporary storage area between the interface
and the next stage of the print process. The data
from each active interface is kept in logical
order.
Non-Crown II printers can focus only on one interface at a time, until completion of that
print job, even though all interfaces are considered active. This principle is called
hot-port interfacing.
When the last data packet from a particular interface is received (symbolically denoted in the
illustration by ), that same interface becomes immediately available for the next print job.
Crown II printers are shipped with the host input buffer and the input buffers set to a
preconfigured optimum value. However, you may manually select other values to further
optimize the Crown II printer for your specific environment.
Crown II printers are shipped with all standard interfaces active.
Crown II printers equipped with an internal hard disk may use a part of the hard disk as
an overflow spool buffer.
t
6 Part 1 Crown Book
INTERPRETATION
The print data from the spool buffer is examined by the
Emulation Sensing Processor (ESP). Each printer
emulation (like PostScript, PCL, GL, etc.) is recognized
by examining the nature of the data. The Emulation
Sensing Processor tries to find a match within the first
part of the print data by comparing the print code to
specific printer language patterns stored within the
printer.
The Emulation Sensing Processor assigns a criteria-
dependent value to a resident printer emulation when it
finds a match. Each emulation is weighed, and either an
emulation is selected or the printer defaults to a user
configurable option.
This avoids the need of selecting an emulation in the printer configuration menu each time.
Moreover, selecting an emulation for each print job would be impossible if the printer is in a
remote network location, serving a group of users.
Two situations may occur:
1. No clear match is found. The Emulation Sensing Processor selects the default ESP
emulation (usually PCL5).
Crown II printers are shipped with the default ESP emulation set to PCL5. You may
select another resident emulation as the default ESP emulation.
2. A clear match is found. The Emulation Sensing Processor activates the appropriate
resident emulation.
The print data is then interpreted, and a special format is generated and stored in the
Display List. Display List data is stored in a compressed format.
There is an important advantage of having a Display List: the pages of a particular print job
stay in the Display List until the print job is completely printed. This automatically enables
two major Crown II features:
1. Automatic Jam Recovery. If a media jam occurs, and if the printer power remains on, the
Crown II printer is able to reprint the page or pages in the engine at the time of the jam
after the jam has been cleared. This enables you to collect your document(s) from the
printer without missing pages and without resending the print job. See A
UTOMATIC JAM
RECOVERY on page 14 for additional information.
Crown Book Part 1 7
2. Electronic Document Collation. Since all pages of a particular document are stored in the
Display List, it is not necessary to send a print job multiple times from the software
application to print multiple copies. This feature enhances printer performance and
decreases network traffic dramatically. For more details, see
ELECTRONIC DOCUMENT
COLLATION
on page 15.
Crown II printers equipped with an internal hard disk are shipped with a preconfigured
segment value for the Display List on the hard disk. However, you may manually select
other values to further optimize the Crown II printer in a specific application. This
allows the Crown II printer to receive and store many print jobs, and it allows print jobs
to be spooled. The process of storing documents before printing is referred to as
Compile-Ahead technology.
8 Part 1 Crown Book
RASTERIZATION
Each time the print engine is ready to print a new page, the
Display List provides the compressed blocks for that particular
page. The Rasterizer translates the compressed blocks very
rapidly into a bitmap version that is stored in the Frame
Buffer. From the Frame Buffer, the print engine reads this
bitmap data.
A bitmap is a graphic representation of a page. All characters
and art representations are printed using tiny dots.
For monochrome Crown II printers, the Frame Buffer contains
a black bitmap only. Crown II color printers translate the
Display List blocks into either four separate bitmaps, (one for cyan, one for magenta, one for
yellow, and one for black) or a black bitmap only for monochrome output.
The illustration demonstrates the color rasterization process with bitmap representations. The
rasterizer processes the data from the Display List into four bitmaps, one for cyan, one for
magenta, one
for yellow, and
one for black.
The print
engine
processes these
bitmaps and
fuses the four
toner layers
onto the media
to produce a
printed output.
Cyan combined with yellow produces green, cyan combined with magenta produces
blue, and yellow combined with magenta produces red. Cyan, magenta, and yellow
combined produce black. In our example, the black is produced by fusing all four toner
colors.
The Frame Buffer always resides in RAM (Random Access Memory = volatile memory).
It is not possible to assign (a portion of) the internal hard disk as Frame Buffer. The
print engine reads Frame Buffer bitmap data continuously at a very high speed, not
allowing delays caused by search mechanisms of relatively slow devices, such as a hard
disk.
Crown Book Part 1 9
The maximum resolution of printing is calculated
directly from the size of the Frame Buffer. The table
below shows the minimum amount of Frame Buffer
memory required for some media sizes and resolutions.
All values are rounded in megabytes (MB).
The printable area is defined as the media size minus
the nonprintable edges around the media. The value of
the nonprintable edges is dependent on the particular
Crown II printer. Some Crown II printers also allow
edge-to-edge printing, which means that the nonprintable area is zero.
Refer to your Crown II printer documentation for the actual printable area(s).

PRINTING
The printing segment is the hardware, often
referred to as the print engine.
To become familiar with the basic functions of a
print engine we demonstrate with a color print
engine.
1. Laser Unit - The laser unit is controlled by the contents of the
Frame Buffer (for each color). For each dot color of the Frame
Buffer bitmap that is turned on, the laser is switched on and
writes an electrical dot onto the OPC.
An electrical dot is an isolated area on the surface of the OPC.
The OPC is initially charged. When the laser beam strikes the
surface, that area is electrically neutralized.
2. OPC (Optical Photo Conductive) Belt (also called Drum) - The
laser unit writes the dots from one side to the other, while the
rotation of the OPC is responsible for the vertical movement (lines
of dots).
3. Toner - Each toner cartridge transfers its toner (one color at a time)
to the neutral areas on the OPC by means of electrostatic attraction
(the toner carries a negative charge). Each OPC belt rotation
transports one color image.
4. Transfer Belt - The Transfer Belt collects all four color images in
succession (on top of each other). Then the total combined toner
image is transferred from the Transfer Belt to the media drawn
from the media cassette. The transfer is also obtained by
electrostatic attraction.
5. Fuser Unit - The fuser unit contains pressurized hot rollers. As the media passes the fuser,
the toner images are melted and fused onto the media. The printed media is then
transported to the output area of the print engine.
The various print engine units are controlled by the Crown II firmware. To detect the status
of these modules, the print engine provides specific sensor signals.

2. CROWN II FEATURES
The previous chapter explained the Crown II printer and introduced some of the Crown II
features. This chapter explains the Crown II features in more detail:
Refer to your Crown II printer documentation for the actual features available.
IMPORTANT NOTES
Before discussing the Crown II features in detail, several important words need to be defined.
ABOUT OUTLINE FONTS AND BITMAP FONTS
A font is a subset of a typeface with a certain size, style (such as italic), and stroke weight
(such as bold). A typeface is the design of a set of characters and usually carries a name, like
Helvetica or Times. The size is expressed in points (1 point = 1/72 inch = 0.35 mm). There
are two basic methods of storing fonts in a printer:
a. Bitmapped Fonts
These fonts are stored as a collection of dots within a matrix. Principally, each font
is designed separately for the best appearance according to the size and resolution
used (the higher the resolution and/or size, the more dots are needed). This
approach has the disadvantage that a separate bitmapped font must be stored for
each size, style, stroke weight, and resolution to be used, occupying much memory.
A further disadvantage is that scaling is not possible without causing a jagged
appearance, although special software routines may help. The illustration shows a
bitmapped font of the italic character I.
b. Outline Fonts
These fonts are size- and resolution-independent since they describe only
the outline of the characters, not the individual dots. The illustration
shows the italic character I stored as vectors. You may describe this
character as follows:
Draw a line from a (X = 1,Y = 0) to b (X = 2½, Y = 7) to c
(X = 3½, Y = 7) to d (X = 2, Y = 0) to a (X = 1, Y = 0).
Fill the enclosed outline with dots (resolution dependent).

Emulation Context Switching Proof-Then-Print
Overlay Printing Printer Management
Number-Up printing Memory Management
Booklet Printing
12 Part 1 Crown Book
This vectored description is independent of the size and resolution. The raster being used in
our example is a matrix of 4 x 7 units (a unit does not have a fixed dimension). When such a
character needs to be printed, the unit number is translated into dots by multiplying the unit
by an integer, according to the required point size and resolution. Only one character
description needs to be stored for all sizes and resolutions used.
An outline font can be scaled and rotated easily. A bitmapped font cannot. Scaling
and/or rotating bitmapped fonts may cause a loss of dots, giving the character a jagged
appearance.
The examples used have small matrices for clarity. Normally, these matrices are much
larger.
ABOUT PRINTER LANGUAGES
The printer receives commands from the computer, which tell the printer how to format the
document being processed. The structure of the print data is called a printer language. There
are basically two kinds of printer languages: PDL and non-PDL. A PDL (Page Description
Language) describes the contents of a page rather than supplying print data from left to right
and from top to bottom. PostScript is a PDL. A PDL may start the data stream with a
prologue. A prologue describes how the contents of the following data (the script) must be
handled. This may invoke routines to handle outline fonts, images, etc.
Another important industrial printer language is PCL (Printer Command Language). PCL
commands are escape sequence codes embedded in the data of the print job being transmitted
to the printer. These escape codes define special features to be executed, such as setting fonts,
point sizes, etc.
ABOUT HARD DISKS
Internal hard disk-equipped Crown II printers may be used extensively for memory clients
and printer-related files. A memory client is a Crown II memory function for one of its
specific segments, like the Spool Buffer, Display List, Emulation, and Emulation Temp
buffer. The corresponding files are in restricted areas of the hard disk. Printer-related files
include optional fonts, emulations, forms, and macros.
Crown Book Part 1 13
Memory clients should be assigned to the internal hard disk, since an external hard disk
is attached outside the interior of the printer and, therefore, an accidental disconnection
may cause a malfunction of the printer.
One internal hard disk may be installed and has a logical name SYS:. A maximum of three
external hard disks may be attached.
Attaching one or more external hard disks requires the installation of the (optional) SCSI
interface.
ABOUT THE FEATURES
Some features of a Crown II printer depend upon the installation of a particular option. In
addition, a certain option or environment may be recommended, although not absolutely
necessary, to take full advantage of the feature. To clearly identify this, we use the following
symbols.

SERVERLESS PRINTING
The illustration shows a simplified section of a typical
network environment. A workstation (WS1) generates
print data from a software application and transmits it
via the network to the network server. The network
server stores the data on its hard disk (in what is called
a print queue). After the data transmission is
completed, the network server sends the print job to the
printer via the same network.
This method has two major disadvantages:
1. The print data is sent two times across the network,
increasing the network traffic.
2. It also takes much longer to print from the time the
workstation sends the data until the print job is
completely printed.
Not only do you have to wait a relatively long time before the printer starts to process the job,
but all other users on the network experience a slower response time as well.
Crown II technology offers a better solution:
A workstation sends the print data directly to the
printer, omitting the network server routing.
All Crown II printers may still print through a
print queue on a network server if you need to use
this method.
All Crown II printers behave like network servers when
connected to a network, decreasing unnecessary
network traffic. This becomes a major benefit when
multiple Crown II printers are active in the same
network. Everyone experiences a much faster
throughput of their print jobs.
AUTOMATIC JAM RECOVERY
Crown II printers provide automatic jam recovery (when enabled through the
Administration/Engine/Page Recovery menu). After you remove any jammed media,
printing automatically resumes from the page the printer stopped at when the jam occurred.
For automatic jam recovery to work, it is necessary to leave the printer turned on when
you remove the jammed media.
Crown Book Part 1 15
ELECTRONIC DOCUMENT COLLATION
Many software applications (in
particular Microsoft Office) offer a
collation button in the Print menu.
Activating this button causes the
application to send the document
multiple times to the printer. This not
only increases network traffic, but the
sending workstation also dramatically
slows down due to the unknown
amount of the print data. For example,
if 3 copies and collate are selected for a
4-page document, the application
generates 3 x 4 = 12 pages of print data.
Note that this 12-page file is nothing more than THREE IDENTICAL 4-page documents.
When collate is not selected and the copy count is set to 3, the application sends the 4-page
file once, with a copy count of 3 embedded in the data stream. A non-Crown II printer
usually prints page 1 three times, followed by page 2 three times, page 3 three times, and
page 4 three times. You must manually collate the pages afterward to obtain the documents.
The example discusses what happens when only three copies are selected. In some cases,
many more copies are needed.
Crown II technology offers a better solution:
With a Crown II printer,
you do not have to select
collation in the software
application when you need
multiple copies of your
document. If the driver
collate setting is turned on,
just enter the number of
copies you need in the driver. The print data is sent once, regardless of the number of copies
you selected. The Crown II printer prints and automatically collates the specified amount of
documents, with the pages in the correct order for each copy of the document. This Crown II
feature allows a very efficient way of producing multiple documents while keeping the
network traffic at a minimum and saving you from manually collating the printed pages into
documents.
Crown II printers are shipped with the collate feature switched off. You are advised to
switch it on after completely setting up your Crown II printer.

EMULATION CONTEXT SWITCHING
Both workstations WS1 and WS2 are independently
creating a document. Workstation WS1 uses a PCL
printer driver, and workstation WS2 uses a
PostScript printer driver. Assume the printer is just
switched on, and each page is sent as a separate print
job. The following is received by the printer in
succession:
1. Print job C is received from WS1.
2. Print job A is received from WS2.
3. Print job D is received from WS1.
This sequence causes the following actions:
1. The Emulation Sensing Processor activates the resident PCL
emulator after print job C was received. The PCL emulator starts
from its default condition. Assume that in print job C some special
features were selected, like downloaded PCL fonts and PCL macros.
2. The next print job arriving at the Emulation Sensing Processor
causes the resident PostScript emulator to be activated. Prior to
activation, the current emulation context (downloaded fonts and
macros previously used) of the PCL emulator is saved in memory.
Then the PostScript emulator is activated and processes the print
job A.
3. Following, print job D from WS1 is received. The PCL driver located in
WS1 still assumes that all emulation context selected during the
previous page is still active. Therefore, before the PCL emulator is
activated, the Crown II printer first uploads the previously stored
emulation context from the Emulation Temp buffer.
Without the Crown II emulation context switching feature, WS1
would have to download the fonts and macros used with each print
job.
This Crown II feature ensures the correct handling of any multi-
environmental situation, utilizing multiple printer emulations. Although this
feature is predominant in networked environments, the same situation occurs when using
multiple Crown II interfaces, each receiving data with a different printer emulation.
