I've modified my #3dprinter so I can use it as a simple #diy #plotter for printing labels onto CDs and DVDs.
The mod is very simple and reversible. All I did was print a box that can hold a pen with a
hole in the bottom so that the pen's tip can protrude out of the box. I then attached it to the print head
assembly via double sided tape and zip ties. To print something I simply insert a #CD labeling pen and push it all the way through and then put a piece of foam on top to hold the pen in place.
The Hewlett-Packard Raster Transfer Language (HP RTL) is a subset of the #PrinterCommandLanguage (PCL) language. It is used to embed true raster images (bitmaps) into #plotter files. Modern plotters (like HP DesignJets) are raster devices, so they need a raster-based language. For backward compatibility they also support the #HPGL2 (formerly HP-GL) vector language, so the HP RTL language is designed for mixing with the HP-GL/2 language.

On the first weekend of May I will be back in Munich at the #VCFe. There I have an exhibition on #AnalogComputing (with a #THAT and a Leybold analog computer, using a modified #Vectrex and an HP XY #plotter as output devices) and I will give a lecture on "Unconventional Computing" (in which the analog computers also play a role).
