I am trying to diagnose an extremely strange problem.
We have an HP Color Laserjet CP1515n network printer.
We need to connect to it from 3 computers; 2 of the computers run XP, 1 runs Win7.
The Win7 computer can connect to the printer over the network and prints with no errors.
The XP machines cannot connect over the network. Instead, we have one connected directly via usb, and that machine shares the printer using the native XP facility for doing so. The 2nd XP machine connects to the printer via the share of the 1st XP machine.
Both XP machines can print images in color (e.g. from paint or irfanview).
However, office documents from Word or OpenOffice with colored text, borders etc. print in grayscale. Sometimes, embedded images in office documents print in color, but colored text always print in grayscale.
I have hunted through all the settings in Word and can't find any setting that would explain this. This behavior occurs in both Word and OpenOffice, and on both machines, so it seems that it's something to do with the printer driver rather than the office software.
When clicking printer options in the print dialogue from within Word, no settings regarding color, grayscale etc. appear under any of the tabs.
I've tried updating the print drivers to the latest versions many times, removing and readding the printers, and nothing seems to work.
Before a recent reformat, both XP machines could print color documents using the same sharing system with no problems.
I am at a complete loss as to how to explain and correct this behavior.
