HP LaserJet Filter

[TABAKIN at vms.cis.pitt.edu]

Dear Glenn:  Concerning Hp laserjet and a Decstation, I have a laserjet iii
running off a Decstation3100 in plain hp mode and also with a postscript cartridge.
The info was provided, after several attempts , by DEC.
The file plain_lj.c plus the printcap file does the trick.
Hope it helps.   frank
