On December 20, 2009, someone (who?) donated a beautiful HP DraftMaster I pen plotter (HP P/N 7595A).
There's a Flickr set of somebody else's DraftMaster for reference.
Our plotter:
- appears to be in good physical condition
- comes with a pen carousel
- comes with one pen holder (holding a #2 pencil, nach)
- has a DB-25 that probably wants to speak HP-GL over RS-232
We need:
- service manuals
- pen holders
- paper
- software that emits HPGL
- a paper holder (probably a wire cage) to catch the print as it finishes
Documentation:
- Manuals and User Guides and product info, from HP museum.
HPGL Software:
- Inkscape, a vector drawing program, can export HPGL.
- Uniconvertor may be able to output HPGL.
Pens:
Program that seems to work:
IN; SC0,40,0,40; SP7; PU0,0; PD100,0,100,100,0,100,0,0; PU50,50; CI25;
Settings:
- Your program needs to use DOS line endings (\r\n)
- Serial is 9600 8N1 on the PC side, plugged into the COMPUTER/MODEM port via a null modem cable
- SERIAL:
- DATAFLOW: REMOTE, STANDALONE
- PARITY: 1
- BAUD: 9600
- HARDWIRE: OFF
Using Inkscape:
- Load (or create) your vector graphic in Inkscape
- Prepare the image for printing:
- Scale the image (Inkscape mm units appear to work correctly)
- Flip the image horizontally (for some reason, the plotter is printing it backwards)
- Select 'save as', then 'HP Graphics Language'.
- Open this file in a text editor, and copy the text
- Paste the file into your terminal program, configured as above (CoolTerm in OS/X or Minicom in Linux)
- Enjoy your plot!
