cups prints poorly, while lpr from command line prints well
Using Suse 9.1 and Cups: Laserjet4Si: using recommended driver Foomatic hpijs.
Graphics print too faintly with this driver. This problem was recognised in earlier versions of the driver and reported as now fixed.
The odd thing is, everything prints nicely from the commandline (lpr filename, as root), but not when I print from an application, (either direct to printer, using lpr in the app's print dialogue, or using kprinter.)
Does lpr process the job in a different way?
I have read all day about cusps and lprng -- but I still do not know exactly where to start looking to get to the bottom of this.
