If you check the LaserWriter II NT/NTX Owner's Guide starting on page 119, there are instructions for cranking the printer up to 57.6K baud. I have our NT running at 38.4K baud (highest practical on sun) with no ill effects. Depending on what your printing, you can get a good 30% improvement in through- put. This is certainly a cheaper solution than purchasing new hardware.

We have a sun 3/160 acting as a disk server for two other diskless clients (a 3/75 and a 3/110). We are running SunOS 4.0.1 and have a Texas Instruments OmniLaser 2115 laser printer. Our problem is this: For standard text output the printer works fine. However, when graphics output or output from TeX is printed (both using Postscript) we run into intermittent problems. These problems occur in several forms. 1) Last page of output is lost. 2) Entire job is lost. This happens most frequently when a print job of any kind immediately follows a Postscript job. 3) Postscript output is overlayed on other output. This frequently occurs when a graph is queued at the same time as text - the graphic output is superimposed on the text output. 4) Printer hangs. This occurs usually when TeX output is printed, although it occasionally happens with other Postscript output as well. Usually the entire job is lost and the printer goes into an infinite waiting-processing cycle. Reset is sometimes ineffective, and we then have to shut the printer off and restart it. We have tried to get around these problems in several ways, none of which have been completely effective. The problems are rarer when there is a delay between jobs, but have been known to occur under any circumstances. Our Postcript driver and print filters are all home grown, and may be the source of the problems. Does anybody know of a reliable and inexpensive printer driver for handling Postcript printout on the OmniLaser? Also, is there a better way to print out TeX output (other than converting to Postscript [we use dvi2ps, which came with TeX, for the translation]? It seems that there SHOULD be a way to print a dvi file directly. I say this particularly since there is a -d option to lpr that is supposed to be used to print dvi files, but it requires a local dvi print filter to operate. Direct responses should be sent to scott@apollo.drexel.edu Any advice would be greatly appreciated. -Scott C. Smith
