Remove your printer from the PC and uninstall the printer software. Now reinstall the printer software and connect the Printer to be detected and installed. Check printer properties to see the ink levels.
Use head cleaning before a test is taken . It is possible that the head is not reacting to the need of the command , can be an issue with ink drying , can also be poor ink cartridge contacts

This printer is compatible with Windows 7, but no Software is available from HP. Windows 7 has inbuilt drivers to support this printer.

Known problem with this machine the fan is located next to the magenta laser scanner at the base of the machine. this fan blows dust on to the scanner lenses and makes the prints light. Needs to be taken apart and cleaned. take it to a local service center if they know what they are doing should be less then an hour.

There is a patch available to print A3/B size in Vista. Click here for details.

The digital readout on the CP1700 is a problem. I have replaced mine now 4 times at a cost of $90 each time, and I'm going to have to do it again or get the new 2800. Just wonder if the 2800 is going to have the same defect.
