All configuration is done via webinterface if not stated otherwise.
Host: Raspberry Pi 4 / Debian 11 64bit Device: Brother TD-4210D, USB Driver: Zebra ZPL 4-inch/203dpi/Direct-Thermal Media: 4x8" labels with spacing/web (german translation is wrong with "Internet", was Web before but don't know what changed.) Print result: only 1" high prints, advancing to next label while leaving rest of the label blank.
1. try:
Installed via apt (lprint 1.1.0/libpappl1 1.3.1-2). Added the TD-4210D with 4" direct thermal ZPL2 profile. Got it to print 5" high test as a 4x5" default setting. Wanted it to change to 4x8" as this is the medium inserted. It always kept spawning to 4x0.945276" (newer versions just 4x1") when started manually with
sudo lprint server. Deleted the printer multiple times, added it again, EPL driver doesn't work. When trying to configure the mediaoe_4x8-label_4x8invia command line, lprint yieldsunsupported media-default keyword value. CoWhen run via the systemd service I could modify it to display 4x8" constantly in the webinterface, but the print on the paper still won't get longer than 1". Also tried changing it back to 4x5" or other formats with no luck.2. try:
Tried to install 1.3.0 from scratch. Uninstalled libpappl and lprint, compiled right from the git, ran into the same issue as in https://github.com/michaelrsweet/lprint/issues/37#issuecomment-1003715367 (libpappl not found) and manually softlinked the /usr/local/lib/libpappl.* to /usr/lib/$1. Failed to find any usb devices afterwards, might have missed some requirements, given up quickly, as I was already struggling for two days with that printer.
3. try:
Installed via snap (1.2.0). Took a while to recognize usb devices, but still same issues as in first try. But in that version the test image from the webinterface is now a bordered checkered pattern instead of fully filled, yeay.
Results
Neither the internal testprint, nor issuing lprint directly on a png (with adequate media setting) did produce a different outcome, also tried printing from Mac and Windows remotely with same moderate success (stopped printing after 1", then advancing to the next label.
