I think so, but for some printers the code strings are very complicated.
But for a Canon BJC-4000 in LQ mode, for example, the User's Manual says
that DC1 (VDU1) starts printing and DC3 (VDU3) stops it. However, the
BEEB won't send DC1/VDU1/CTRL-@ without a 'fix', IIRC. I don't remember
what the 'fix' is, though. (8-0(
