Dear Maintainer,
I was able to reproduce this issue, kind of.
I guess the debian release name stored in /etc/os-release is too long.
Therefore in /usr/lib/cups/filter/hpcups in function IsChromeOs
the local array os_name with length 30 is overwritten by 1 byte.
At least that issue I received when executing the cupsfilter command from
the previous mails, with the ppd created when setting up a printer selecting
the "HP Photosmart c4700 Series, hpcups" driver. (Details in attached file.)
The easiest fix might be to make this array in IsChromeOs e.g. 100 bytes long?
Kind regards,
Bernhard
