General Definition of Safety Symbols
International caution symbol (refer to manual): the product is
marked with this symbol when it is necessary for the user to refer
to the instruction manual in order to protect against damage to the
instrument.
Indicates dangerous voltage (terminals fed from the interior by
voltage exceeding 1000 volts must also be marked).
Protective conductor terminal. For protection against electrical
shock in case of a fault. Used with field wiring terminals to
indicate the terminal that must be connected to ground before
operating equipment.
Low-noise or noiseless, clean ground (earth) terminal. Used for a
signal common, as well as providing protection against electrical
shock in case of a fault. A terminal marked with this symbol must
be connected to ground in the manner described in the installation
(operating) manual, and before operating the equipment.
Frame or chassis terminal. A connection to the frame (chassis) of
the equipment, which normally includes all exposed metal.
Alternating current
Direct current
Alternating or direct current
The WARNING sign denotes a hazard. It calls attention to a
procedure, practice, or the like, which, if not correctly performed
or adhered to, could result in personal injury.
The CAUTION sign denotes a hazard. It calls attention to an
operating procedure, practice, or the like, which, if not correctly
performed or adhered to, could result in damage to or destruction
of part or all of the product.
Take care not to cut yourself on the encoder strip inside the plotter.
1Ć2 Product Information
C3187Ć90000
Description
HP DesignJet 200 and HP DesignJet 220 plotters are largeĆformat, monochrome, inkĆjet
plotters that provide hardcopy output of computer program data.
LargeĆformat plots of high resolution and quality are generated for applications such as
D ComputerĆaided design (CAD)
D ComputerĆaided manufacturing (CAM)
D Mapping
D Mechanical and architectural drawings
D General drafting
The plotters accept drawing data from CAD software programs supporting the following
languages:
D HewlettĆPackard Graphics Language (HPĆGL), a vector language
D HPĆGL/2, an enhanced version of HPĆGL
D HewlettĆPackard Raster Transfer Language (HPĆRTL), a raster language
D Printer Job Language (PJL)
The plotters support HPĆGL/2 with both the Japanese Kanji and the Roman character sets.
The plotters operate with a number of computer systems and graphic terminals, using either
RSĆ232ĆC or Centronics/BiĆTronics interfaces. (More ' chapter 5, w Input/Output Interfaces.)
Customers can connect their plotters to a network through an optional HP JetDirect EX
external network interface. The following network operating systems are then supported:
D Novell Netware (Ethernet and Token Ring networks)
D LAN Manager (Ethernet and Token Ring networks)
D TCP/IP (Ethernet networks only)
D Apple Ethertalk (Ethernet networks only)
The plotters have a standard 2 megabytes of onĆboard random access memory (RAM). They
also have one RAMĆexpansion socket, which can hold an optional 2Ćmegabyte, 4Ćmegabyte or
8Ćmegabyte, single inĆline memory module (SIMM). The maximum RAM is therefore 10 MB.
1Ć3 Product InformationC3187Ć90000
The accuracy of the plotters in drawing a vector is0.38 mm (0.015 in) or 0.2% of the
specified vector length, whichever is greater, at 23
_C (73 _F) at 50Ć60% relative humidity, on
HP special polyester film.
The resolution of the plotter output is measured in dots per inch (dpi). (Explanation '
chapter 5.) The plotter resolutions for different plotĆquality settings are as follows:
Plot/Print Quality HP DesignJet 200 HP DesignJet 220
Draft 300 x 300 dpi, dot depleted 300 x 300 dpi, dot depleted
Final True 300 x 300 dpi True 300 x 300 dpi
Enhanced – Addressable 600 x 600 dpi.
The plotting time for one plot on paper is as follows:
Plot/Print-Quality HP DesignJet 200 HP DesignJet 220
D/A1-size plot E/A0-size plot D/A1-size plot E/A0-size plot

Final approx 5.0 min approx 10.0 min approx 3.1 min approx 5.3 min
Enhanced – – approx 6.5 min approx 10.6 min
The plotter legs and media bin are optional.

(Cable part numbers ' chapter 10.)
Choosing an Interface Cable
(Instructions ' User's Guide, chapter 1, w Choosing an interface cable.)
&& A short cable (less than 15 meters or 50 feet) is recommended
for the RSĆ232ĆC interface. A longer cable is permissible, provided the load capacitance does
not exceed 2500 picofarads.
& Use a short cable (less than 2 meters or 6.6 feet)
for the parallel interface.
