7550A Hp Plotter
I got my hands on a HP plotter and am trying to make it work (as in send .eps/.ps files to it). Documenting
windows
bought usb <> serial, apparently lots of fakes so I downgraded a windows driver to make it work, it didn't
Python library: https://github.com/drepetto/chiplotle (skipping for now)
linux
trying to connect to serial using linux, so far, not so good (tried both modem and direct ports)
keep getting `pl2303 ttyUSB0: pl2303_get_line_request - failed: -32` error

houdini wire render (wren) ps files are not really postscript, figure out a way to convert them with imagemagick
dmesg: device messages (figure out your tty port)
tail -f /var/log/syslog : same but all commands
