This is mostly what I did for my SGI Indy + Indycam + thermal printer 
year before last.
The Indy wrote files to an NFS share on a Rasperry Pi, which watched for 
new files with inotify and piped them into CUPS to run the USB-connected 
printer.  That way when the Indycam took a new photo and saved it, it'd 
immediately print.

I've definitely seen old HP pen plotters hooked up direct to UNIX-y 
workstations; you need applications that generate HPGL output, that's 
the tricky part.  You don't really have a driver per-se in the print 
server, you just dump the raw HPGL into the serial or parallel port and 
the plotter interprets it.
