Hi I think your printer has a parallel connector ( big D shaped socket with wire clips each end) on it if your pc also has a parallel plug get a parallel lead and install the drivers to use LPT1 this should remove the faulty USB plug from the problem
good luck Ian

Hello and welcome draepeacock !
The only solution is a workaround :
If you have the W XP install disc , you can install a virtual version of W XP on your machine from http://www.vmware.com/products/player/
If you still have the install disc , you can also partition your primary and install W XP on the new partition from http://download.cnet.com/Partition-Wizard-Home-Edition/3000-2094_4-10962200.html.Back up your data first.

Both are easy and safe , no specific knowledge required .
Regards .

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.

Now- disconnect your printer from your computer and don't reconnect until you are instructed to do so. OK-run your printer drivers and follow directions-connect when told to-
And that should do it.
