Line Printer) software is a reverse engineered version of the Berkeley LPD software. It has (gasp!) error messages. Timeouts. Automatic restart of hung jobs, if you want. Try getting it from julius.cs.umn.edu, anonymous ftp, /public/PLP.3.0.tar.Z. If you have a transcript source license, I can send you a "fixed" version that appears to solve several problems on Sun4/4.0. If you have a binary license, I can send you a binary... I have observed the problem with the laserwriter several times before, and it has usually been tracked down to serial line noise problems. Patrick Powell Prof. Patrick Powell, Dept.
