[cups] Printer not usable from command line, "Filter failed"

[Zdenek Dohnal]

Hi Jarvis,

from logs:

D [23/Jun/2020:15:06:23 +0200] [Job 20] Unsupported OTF font / glyf table

D [23/Jun/2020:15:06:23 +0200] [Job 20] Brother_MFC_L2710DN_series:
fontembed/sfnt.c:651: otf_get_width: Assertion `0\' failed.

D [23/Jun/2020:15:06:23 +0200] [Job 20] PID 9315
(/usr/lib/cups/filter/texttopdf) crashed on signal 6.


The printing crashes on texttopdf filter - please provide the file you
are trying to print, the latest file from /var/spool/cups which starts
with 'd' and the ppd file of your print queue (file from /etc/cups/ppd,
has the same name as your print queue).

With those information, please file a ticket on
https://github.com/OpenPrinting/cups-filters .
