Guilmette >Release: FreeBSD 3.3-RELEASE i386 >Organization: E-Scrub Technologies, Inc. >Environment: Attempting to print a Postscript to my Postscript-capable HP LaserJet 5MP printer (via `cat' to /dev/lpt0). >Description: Just doing `cat' of a postscript file to my Postscript printer (whose device name in /dev/lpt0) caused the lights on the printer to blink for awhile, but then nothing came out. After futzing around for awhile, I found (purely by trial and error) that using `lptcontrol -e' (on the default /dev/lpt0 device) allowed me to actually get the things that I was cat'ing to /dev/lpt0 printed by the printer. Obviously, on my system at least, the /dev/lpt0 device should, by default, START OUT in ``extended mode'' (whatever the heck that is). Otherwise, nothing prints, and the typical dumbo user (as exemplified by me) will be left scratching his head, wondering what the dickens is wrong. >How-To-Repeat: Get an HP LaserJet 5MP (or any other pinter I suspect) and just plug it into the first parallel port of any standard/normal circt last 1997 PeeCee. Then try to cat some file to /dev/lpt0 and see if anything prints. It won't. >Fix: Beats me. If posible, perhaps the kernel should auto-detect cases where a given parallel port can support ``extended mode'' and it should then just set that port to that mode by default, at boot time. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
