Ok, I misinterpreted "system locked up" to mean your FreeBSD system
froze. From the looks of things, that's not the case - the sending
program just locks up.

It's probably a winprinter. You can use those on FreeBSD if there's a
driver for it for ghostscript. The ijs driver should support the
656C. From there, you can either install apsfilter - which will
install an a2ps port to print ascii, or install magicfilter and then
use your favorite ascii to postscript printing tool to print straight
text. I prefer enscript for that. Either one will detect various
graphics formats and automatically translate them to postscript to be
printed via ghostscript.
