^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
reclam ation 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
