Comment 34 for bug 777670

I can confirm most of the above problems:

Ubuntu Natty 11.04
HP Color Laserjet 3600
hpcups 3.11.5
libjpeg62

testpage will print like #1

printing it to pdf via cups-pdf I get the real colors in pdf, printing the pdf to HPCLJ3600 i get wrong colors on paper. the workaround that has worked for me was to select 'best quality' in the print menue of adobe reader's print menu.

lpr command that works would be:
lpr -P HP_Color_LaserJet_3600 -o PageSize=Letter -o PageRegion=Letter -o Duplex=None -o InputSlot=Auto -o ColorModel=RGB -o MediaType=Plain -o OutputMode=Best -o OptionDuplex=True
