As one that has had to struggle with ancient plotters: What does the "beast" speak? Common answers would be: PTL (plotter transfer lang), HP-GL (hp graphics lang), PS (postscript, duh..), or possibly HP-RTL(hp raster tranfer lang). I'd wish for PS and do "cat file.ps > dev/lp0" and see what happens. Never seen a Calgraphics, so you probably won't be *that* lucky. I guess what I'm getting at is: if you can figure out what format the plotter wants it's input in, there are a number of ways to make it happen in cups, ghostscript, etc.... Were you lucky enough to get a "sample file" with the plotter drivers ...? Chris
