HP DESK TOP 840C PRINTER CONNECTION


Hello,

They do make adater cables for such problems. Here is just one such example: Parallel to USB Cable

Make sure you get the correct 25 pin cable. They have this type also:

Parallel to USB Cable 2

You can search the web for more companies. Google parallel to usb printer cable.

After saying all that and checking your printer info, I see that the 840c has both a parallel and a USB cable port. See page 21 of the manual: HP 840c Manual

If you go that route, you will need a standard USB cable. The shorter the better, but no longer than a 6' cable. Make sure you follow the iinstallation instructions for the USB setup in the manual.

Thanks for using Fixya.

Dip the head area of cartridge in hot water by 2 to 3 seconds two or three times and use tissue to check the color, if all three color comes out to tisssue paper, then it works else you have to replace the cartridge.
