After much Googling and forum searching, I'm posting in hopes of someone else having this archaic printer.

Research dug up these links:

http://www.linuxprinting.org/piperma...q2/000840.html , which led to:
http://www.linuxprinting.org/show_dr...?driver=lm1100 , and finally:
http://www.burntcouch.com/lexmark/ , which is 404.

The OS will spool the job, and the queue will chew on it for a few moments and then remove it, just like it thought the job finished without error; but no paper comes out.
I tried a few of the generic drivers, and the printer head will start jumping back and forth, making several loud grinding noises, so at least I know there's communication happening.

A few days ago, it printed fine under WinXP; so the printer and cables at least work.

Anyone?
Thanks again.
