NAME
thinkblt, think - print on ThinkJet
SYNOPSIS
thinkblt [ stream ]
think [ -o stream ] [ files... ]
nroff -Tthink ... | think [ -o stream ]
DESCRIPTION
Thinkblt downloads an interrupt driver for the printer, provides a menu
of operations for printing various data residing in the terminal, and
sets up a stream ($HOME/.THINK 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 prints whatever bitmap is currently selected, in
analogy to blitblt(9.1). The widest printable bitmap
is 640 pixels across.
print mux buffer prints 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; see the
nroff(1) terminal driving file for a complete list. Both nroff(1) and
pr(1) will paginate properly if top-of-form is set so that the paper
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 powering
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(1) character names are not currently supported by any
other device.
