I tried using pdf2printable.tcz (to convert a pdf file to pwg file) in a barebones TCL box (my router) and the terminal became filled with these messages:
some font thing failed
some font thing failed
some font thing failed
some font thing failed
some font thing failed
This warning/error is not very helpful, so troubleshooting was long and tedious. The fix turned out to be simple: Loading Xorg-fonts.tcz.
In the TCL14, TCL15, and TCL16 x86_64 repos, can one of the devs please add Xorg-fonts.tcz to pdf2printable.tcz.dep?
