I have recently installed a HP Laserjet II on one of our computers. I have been able to print regular files (ASCII) with no problem. But we need to be able to print tex files we have dvi-to-hp program that produces the correct file. But when we use the lpr command we get nothing put garbage. We think the control signals are getting filtered out, how can we prevent this. Thanks Cary E. Burnette kerm@mcnc.org

Most of the filters do peculiar and undocumented things. Some, like ln03rof, do fewer peculiar things than ln03, so you might want to give that a try. When in doubt, specifying /bin/cat for the "accounting filter" is a good starting point. I posted the source for the BSD 4.3, "do almost nothing" filter where a while ago, send e-mail if you can't find it and could use a copy... Remember, there is a section on the printer spooler in the supplementary documents - the system is more complicated, flexible and perverse than meets the eye, but not as bad as it seems when you're looking at all the printcap options... 8-) [sorry, it's getting late] -- George Robbins - now working for, uucp: {uunet|pyramid|rutgers}!cbmvax!grr but no way officially representing arpa: cbmvax!grr@uunet.uu.net Commodore, Engineering Department fone: 215-431-9255 (only by moonlite)
