Bug#796713: system-config-printer: Option "fit-to-page" broken, always on. Cannot print out true to size.

[Ingo]

Package: system-config-printer
Version: 1.4.6-1
Severity: important

Dear Maintainer,


   * What led up to the situation?

Just creating a page with a frame in LibreOffice-writer and printing it out results
in a downscale to appr. 90% of the exact measures. (I use that feature as a place
holder for photo). Checking the printer settings in "system-config-printer", tab
"Job properties" shows the chaeck-box "scale to fit page" de-selected. I cannot
check/unchech that box even though root-PW is requested and given. 
Whatever I do, the page is always scaled down ihnoring measures as suppied within
the document by LibreOffice.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

I found that there by default is an option in /etc/cups/printers.conf:
    Option fitplot True
As it cannot be changed by "system-config-printer" I set it manually to "False"
and not suprising: it works. I get perfectly sized printouts.

   * What was the outcome of this action?

The outcome unfortunately is that this manual setting in /etc/cups/printers.conf
is reset to "True" or, if I erase the whole line the Option is added again as
soon as I use the graphical printer configuration to apply changes. Th checkbox
does not report the actual setting instead it always resets to "True".

   * What outcome did you expect instead?

This usefull tool to configure printers on XFCE4-dsesktop should work as exüpected
and as it did for years in Wheezy and still does.
