I did consider using Cairo but figured a simple PDF driver would take care of most of the work. That would have been fine if not for the pathforall operator. I ended up doing all the stroke path implementation for dashed lines as well. I used to work for the UK distributor for QMS who were Adobe's second largest OEM for PostScript so I had a lot of exposure to early PostScript printers. Also I've always thought the LaserWriter was more significant to Apple than most people realise. I lost count of the number of companies I visited who had a bunch of Macs and a LaserWriter networked over AppleTalk.
