#Hp printer 940c troubleshooting install

It got part way thru the install (some bar moved left to right) and then asked her to connect the printer usb cable.ДЄT THAT POINT I (ON PHONE) realized I had forgot to have her remove the 940c from the Control Panel>Add/Remove Programs list before inserting the printer install CD. OK I told her (without knowing that there were still 940c's in Control Panel>Printers) to put in the printer install CD and proceed. In fact she left at least one and maybe two (one left was a 940c network printer via Windows printer sharing and possibly the local 940c too, but I am not sure about the latter and obviously the latter one matters). #1 I told customer to delete all 940c icons in Control Panel>Printers. Fact: If a new Samsung printer is installed onto the PC that Samsung printer works so the basic Windows Printing part of the OS is working and is fine. Problem: HP940c printer (attached to PC with usb cable) does not work. And I could not see what could possibly go wrong. I fix PCs for a living and this got screwed up BECAUSE I advised customer over the phone to avoid a 2 hour round trip (probably unpaid, don't ask) drive. Of course if you have a different idea that will work, then I am all ears !!!!

As an example both Symantec (Norton) and Mcafee provide such forced uninstall links for on their web-sites (different kind of SW but same idea). I believe that the ONLY WAY AN EE EXPERT CAN HELP ME HERE IS TO PROVIDE A LINK TO A **FORCED UNINSTALL** PROGRAM FOR ALL HP PRINTERS OR JUST THE 940C. I concede that I made some mistakes here BUT need help getting out of this mess.
