An intro to Pen Plotters
Can&#x27;t believe my old post got picked up! If anyone&#x27;s looking to get a plotter I would still highly recommend an old HP 7475A as a gateway drug — they&#x27;re relatively cheap, not too big (the size of a large-ish inkjet printer) and incredibly well made. I&#x27;ve had a lot of fun using the Geomerative library for Processing.org to play around with my plotters, but really anything goes as long as you can access your serial port and don&#x27;t mind reading the plotter&#x27;s manual. I generally save the HPGL output to a text file and then use a small utility app I&#x27;ve written to send it to the plotter. Sometimes I&#x27;ll check the output in Cenon.app before wasting any paper or ink.
