Package: printer-driver-escpr
Version: 1.6.8-1
Severity: important

Dear Maintainer,

I have cups installed on a headless system, but can't print anything.
I ran strace on what the backend does, and it's doing:

stat("/etc/cups/ppd//usr/lib/cups/filter/epson-escpr-wrapper.ppd",
0x7ffe5cf95530) = -1 ENOENT (No such file or directory)
PPD file not found, or PPD file is broken. Cannot get option of PIPS.
+++ exited with 1 +++

The path
"/etc/cups/ppd//usr/lib/cups/filter/eipson-escpr-wrapper.ppd"
is obviously wrong, the real path is /etc/cups/ppd/Epson_2530.ppd

The environment passed to the backend is:

AUTH_INFO_REQUIRED=none

and it's spawned with such command line:

Hello Matteo,

I chose the Epson-WF-100_Series PPD at random to test how it behaved. It
was not intended as a substitute for the PPD for you printer.

I am in two minds here. I cannot reproduce any buggy behaviour and you
can print. One the whole I am going to come down in favour of closing
the report. Please feel free to reopen it if you can reproduce buggy
behaviour using the techniques we have used.

Regards,

Brian.
