Print part labels on a Zebra label printer

[salfter]

I tried doing this with the PDFs generated by PartDB, but the relatively low resolution (203 dpi) of the printer meant that QR codes were so fuzzy as to be unscannable. As a result, I came up with this:

It creates sharp, easily scannable labels on any printer that understands EPL2. I've tested it with an LP2844 and a GK420t; the latter is what produced this:

(The slight fuzziness here is probably just a depth-of-field issue from holding my phone too close. :) )

Lots of command-line options let you customize things like label size and which server to use. I've tested it on both Linux and Windows; if you're running Arch Linux, I've already added it to AUR:
