Is there a device you can recommend for printing (sticky) labels occasionally? I have a little Brother printer for those narrow little labels, one with a rubber keyboard, but would love something with sticky labels AND Linux connectivity. Something I could script when organizing my workspace, parts, ... to print the appropriate label.

If your printer speaks ZPL, I might have a solution in the near future. I'm working on a ZPL server that handles printers (USB and network), label templates, CSV uploads (for batch printing labels), and the like.
