Brings back memories of trying to get HPGL, PCL, or other non-postscript printers working with various flavors of Unix, lpd filter scripts, trying to get a form feed to spit out the paper, etc. Pretty sure there's an ugly Perl script of mine still doing this at a previous employer.<p>My friends and I used to create a little mayhem sending bursts of form feeds to the DEC band printer in the lab when the teacher was near it. It would shoot out paper 5 feet or so.
