My printer is HP LaserJet P1102w, which requires print/foo2zjs. That stuff was originally released for Linux. I had to google around for a bit before I was able to get the CUPS install to accept it on FreeBSD. This was a long time ago, and I don't want to reproduce the details of how I pulled that off. I think I fed the driver to https://localhost:631 web interface for CUPS in the end. No messing around with compat-linux stuff. My point is, to answer your question, it's perfectly possible.I am wondering if it is possible to use a Linux printer driver for CUPS that contains a filter program binary in FreeBSD.
