Adding '-dUseFastColor' to your gs 9 command line may help you get a behavior closer to gs 8's. If that works for you, read what it does in the doc. Hi Hin-Tak, thanks for quick answer. In Debian8 (with cups 1.7.5-11+deb8u1 and ghostscript 9.06~dfsg-2+deb8u1 I added "dUseFastColor" to /etc/cups/cupsd.conf, followed by /etc/init.d/cups/ restart. testpage-debian8_01.jpg (attached to my comment yesterday) stays unchanged. Same with "-dUseFastColor". To be honest, I think you mis-filed this. If you had filed this under CUPS driver it would have gone to Till, who has a better chance of seeing what's wrong with the zjs driver's color. BTW, I believe the zjs driver is driven through some shell script wrapper foo2zjs-wrapper and foo2zjs-pstops, and you need to edit those. Editing cups config has not effect on the zjs driver's behavior, as far as I know. The file /usr/bin/foo2zjs-wrapper contains a line like this: GS="$GSBIN -q -dBATCH -dSAFER -dQUIET -dNOPAUSE -dNOINTERPOLATE" Try to add "-dUseFastColor" here so that you get something like this: GS="$GSBIN -q -dBATCH -dSAFER -dQUIET -dNOPAUSE -dNOINTERPOLATE -dUseFastColor" Does this improve your printouts? Please contact the author of foo2zjs about this. Adding dUseFasdtColor will not change anything. Saturation problems remains. Btw:-dINTERPOLATE was not part of my /usr/bin/foo2zjs-wrapper. I added (printout becomes slightly smaller) and combined with and without dUseFastColor. Saturation problem stays unchanged.I informed Rick Richardson, author of foo2zjs-driver here: http://foo2zjs.rkkda.com/forum/read.php?13,3922 Maybe he can support you solving the saturation problem. This bug report is already near three years old. Therefore I am closing it with WONTFIX. If you are still suffering this problem please re-open. |
