GRAPHICS HARDCOPY OPERATIONS
There are two methods ofobtaining a hardcopy of the contents ofgraphics memory. One method
uses the function keys and graphics keys on the keyboard. The other method uses escape
sequences which may be coded into a program running on a host computer. The hardcopy may
be output from the optional integral printer or from an external printer connected to the
external printer port at the rear of the terminal.
When the optional integral printer is selected as the output device, a dot-by-dot transfer of the
graphics memory is made on thermal paper. The image is 14.5 cm by 11 cm (5.75 by 4.25 inches)
centered on the paper. The transfer takes approximately 30 seconds.
The external printers that can be used for graphics hardcopy are the HP 2671G, HP 2673A, HP
2932A, and HP 2934A. If the terminal is equipped with the alternate peripheral interface, the
HP 82906A can also be used.
Plotters that can be used for graphics hardcopy include the HP 7220C/T, HP 7221C/T, HP
7580B, and HP 7585B. When equipped with the alternate peripheral interface, the HP 7470A,
HP 7475A, HP 7580B, HP 7585B, and HP 9872C/Tcan be used as graphics hardcopy devices.
Initiating A Transfer From The Keyboard
The G. COpy key on the graphics/numeric pad initiates the graphics transfer. The keypad must
be in graphics mode for the GRAPH COpy function to be performed. • NUM PAD toggles the
function of the keypad between graphics mode and numeric mode. Pressing the G. COpy key
generates an error message if no valid destination device has been specified.
The destination(s) may be selected by pressing _,
device control, to devices.
You may
then select
TO EXT OEV, TO ALT PRT
and/or
TO IHT PRT. TO EXT OEV
selects the external
printer port, and
TO I HT PRT
selects the optional integral printer.
TO AL T PRT
selects an
external printer on the alternate peripheral interface.
Using The Ec & p Escape Sequences
Coding a program to transfer graphics data either to the integral printer or to the external
printer, or both, requires selecting the graphics memory as the source ofeither or both printers
as the destination.
graphics memory as the source:
7s
integral printer as the destination:
6d
external printer as the destination:
4 d
alternate printer as the destination
5 d
Examp Ie:
Define graphics memory as source and integral printer as destination.
