So Inkscape can’t print for me, but Inkscape can save a pdf which I can print. The I’d bit is that when it fails to print, it locks the printer as well. I should look into a firmware update, or I should look into what kind of data that Inkscape is trying to send. I’d have to guess that it’s… hmmm… an end-of-line mismatch? That might make sense.
Peter's stuff.
