My printer HP Deskjet 2515 does want to print from my computer it always did but not any more if I print test page the colours are ok but when I want to print a document the paper comes out blank

Check in printer properties., mught be you selected as print in gray scale or black & white., there select print in color mode..

If the test page is working in colour then it's most likely your printer settings. Go into the settings when printing and ensure that greyscale or black/white printing is not turned on.

please printer driver setting .. give a print ...select your printer and go to printing preference then go to color tab check for any setting like print in color in gray and print in color ....... select print print in color ......and try ....

deskjet 920c will not print, green light flashes and blank paper comes out. Printer will print test page perfectly.

Try printing a test page. If it comes out missing colors, the you color cartridge is bad. HP test pages will print each of the 3 colors by them selves, so you can see if you are getting all colors. If this prints ok, the I would think it is not a printer problem.

check printing preference on color tab.

before you print, you have to check your options.

For example, if you want to print black and white, when you select PRINT from the menu, you click on PROPERTIES to the right side or bottom side, depending on which windows you use, then select grayscale/black and white, etc in the options that will follow to correctly use your ink, you can always REMOVE the ink from your printer as you only want to print black and white or non color pages.

I hope this helps you.

I had the same problem and the solution I found was to uninstall and then reinstall the printer driver. For some reason this worked. I now get the correct colors.

reinstall the drivers

try cleaning your printer cartridges, go to printer preferences,then go to the service tab, try cleaning from there.
hope it helps
