THINKBLT(9.1) THINKBLT(9.1)
NAME
thinkblt, think - print on thinkjet
SYNOPSIS
thinkblt [ stream ]
think [ -o stream ] [ file ... ]
nroff -Tthink ... | think [ -o stream ]
DESCRIPTION
Thinkblt downloads an interrupt driver for the HP ThinkJet printer,
provides a menu of operations for printing various data residing in the
terminal, and sets up a stream by default) on which think can print
data from the host. It is intended to be down-loaded once per terminal
session. Most of the menu items are identical to those of blit-
blt(9.1). The remaining ones are:
print bitmap Print whatever bitmap is currently selected, in anal-
ogy to blitblt(9.1). The widest printable bitmap is
640 pixels across.
print mux buffer Print the mux `snarf' buffer.
reset printer Sends ESC-E.
While the printer is operating, a different menu allows one to abort or
pause the print operation. The printer has a fairly large internal
buffer, so response may be slow.
Files on the host may be printed by giving them as arguments or stan-
dard input to think. When used with nroff, names like \('e may be used
to access the special characters provided by the hardware; the nroff
terminal driving file has a complete list; see troff(1). Both nroff
and pr(1) will paginate properly if top-of-form is set so that the pa-
per tear is aligned flush with the top of the metal clip which holds
the absorber.

BUGS
The 5620 ROM program is unable to cope with interrupts from the
printer; it is therefore necessary to download mux(9.1) before turning
on the printer.
Thinkblt substitutes its own interrupt routine for the (trivial) one
provided by mux(9.1). The latter is restored upon exit, but havoc may
result if the thinkblt layer is simply deleted.
The special nroff character names are not currently supported by any
other device.
