Use.”

^D, ^T, and ^C Commands

The bitmap graphics of the LaserJet series II printer require that

8-bit data be transmitted to the printer. Hence, when the printer is

in the LaserJet series II printer emulation mode, it configures the

communication parameters so that all 256 characters are

transmitted uninterpreted to the emulator. Thus, the end-of-file (^D

for PostScript jobs), the ^T status request, and the ^C job interrupt

command are eliminated by emulation. ^L is a formfeed command

in HP PCL.

This means you must send a form feed command at the end of each

document.

Storage of Information

Management of stored information for the emulator is similar to

PostScript: the emulator runs a series of “jobs” with storage

reclamation at the end of each job. Since transparent

communication in the emulator makes sending any kind of

end-of-file character impossible, the only end-of-file is either a

manual reset or wait timeout. The length of the timeout period may

be set by the user, and infinite is one of the options.

The LaserJet series II printer allows fonts and macros to be

downloaded into the printer for use in printing subsequent pages.

On the LaserJet series II printer, there is a hierarchy of “temporary”

and “permanent” for both fonts and macros. Temporary ones are

deleted by a printer reset (e.g. <ESC>E), and by explicit escape
