For about a half year we have a Texas Instruments OMNI-2115 and an Apple laserwriter. Both machines are 300 dpi and are used with Postscript. However, the resolution of the omni-2115 is worse than the apple laserwriter, as if the omni-2115 does not use the full 300dpi, but about 100 dpi. Does anybody on the newsnet has similar experience, and/or does anybody waht could be doen about this? Awaiting your reactions, Hin Oey -- IBBC-TNO -- Netherlands -- uucp: mcvax!tnosel!hin

All the print engines I've seen with write-black seem to do better on printing text and sparse graphics (mostly lines - thin ones at that) and the write- white, which have better solid blacks (graphics with lots of filled areas) Joel Garrett University of Delaware arpa: garrett@udel.edu

Sounds to me like write-white problems. The TI produces a very anaemic character with a write-black font. It's not that much better with a write-white font, but at least it's readable. Pierre A. MacKay TUG Site Coordinator for Unix-flavored TeX
