A while back I bought a DYMO LabelManager Plug N Play Label Maker to help organize things. Before I bought it I had done some cursory searching and saw there were Linux drivers, and I set up CUPS, fixed permissions (of course), and installed the DYMO drivers, but nothing was showing up.
Well, turns out there’s a reason for that – the LabelManager PnP actually labels itself as a HID device, not a printer! (
lsusb -v to peep the details)…
Luckily, with a bit of searching, I found a nice little Python 3 script called dymoprint (github) that reverse-engineered the USB protocol and works perfectly. Another dev subsequently wrote a Perl script that generates 64px tall bitmaps to the printer. (I have lots of existing image generation code to build a Python version of this, but honestly, the first dymoprint script does just about everything I want, which is just to print some simple labels).
I saw that someone else did get it to run on CUPS – it looks like you have to set up modeswitching, but I haven’t tested that personally.
