Subject:  cups/ppd-cache.c: Put cupsSingleFile into generated PPD
X-Git-Tag: v2.4.6~3^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1504527b2415a4b67b0e3e17593b053f3628746f;p=thirdparty%2Fcups.git

 cups/ppd-cache.c: Put cupsSingleFile into generated PPD

Some printers are not able to print multiple files in one job via IPP
Everywhere. Adding the PPD keyword enables the feature on all printers
in exchange for performance degradation (there is a 1-2s pause between
printed files).

Fixes #643
