Office jet G510-nz won't print says no computer connection

SOURCE: blinking/flashing lights(orange & green) &

that is because ur head of ur printing cartridge is damaged.

remove ur cartridges black as well as color
n install only black cartridge n check d blinking of lights on ur printer if it doesn't blinks it's mean ur black cartridge is OK but ur blinking of light on ur printer is same it's mean ur head of black cartridge is damaged
after this process remove the black one cartridge and install the color one cartridge n check d blinking of lights on ur printer if it doesn't blinks it's mean ur color cartridge is OK but ur blinking of light on ur printer is same it's mean ur head of color cartridge is damaged
now take a dry cotton cloth n gently clean ur cartridges head install both cartridges on ur printer n check ur blinking light on ur printer that will work only if u r too lucky other wise u have to purchase a one cartridge.

Hello.

Here's some help from HP Support:

Check the Print in Grayscale setting and Print a diagnostic page, etc.

SOURCE: My office jet G85 won't print. No error messages appear,it has a new color cartridge,it copies, but won't print from my computer.

If it copies ok, then the issue is either the way it is cabled to computer or the print driver software settings on pc.... How is it connected via USB? Check port and correct driver is in windows/control panel/printers. Reinstall.
