The HP7475A either takes A4 or A3 paper. The thickness of the paper is very flexible. | The HP7475A either takes A4 or A3 paper. The thickness of the paper is very flexible. | ||
Before plotting on a A3 paper, you need to press SIZE + ENTER on the plotter to change the format. | |||

It will display a list of all available serial devices, in the console. In Windows, the ports are named COM1, COM2,... You can try all of them until you find the right one, or check the Windows Device Manager to find out. If you have a Mac, you need to look for a name like "/dev/tty.usbserial..." Copy that name from the console and use it one of the programs that are supposed to talk to the HP7475A. | |||

Fortunately, there is a HPGL library for Processing, which can convert your sketches to HPGL files. | Fortunately, there is a HPGL library for Processing, which can convert your sketches to HPGL files. | ||
Another approach is to export a .svg file with Processing and to convert it to .hpgl with InkScape. (The files produced by inkscape are not compatible with my “HP7475A_feed_hpgl_file_01” sketch yet). InkScape also has the option to directly send graphics to the plotter, but I had no good experience with that. It also needs original HP Pens (or 3d printed adaptors), as it sends SP; commands, which let the plotter attempt to change the pen, before beginning to draw. | Another approach is to export a .svg file with Processing and to convert it to .hpgl with InkScape.
