So I uninstalled, performed a rollback to before the upgrade, then reinstalled the original Kodak software from the original CD, not connecting the printer until after the software install had completed. This got me partial success, but left a new mystery:
The driver installation process now completed properly, the printer appears in Control Panel/Printers and faxes, the drivers appear correctly in the Server Properties dialogue, the Kodak home center software says the printer is connected, and I can even print a calibration page successfully from the Kodak software …
BUT I still can’t print from any other program (”Windows cannot print due to a problem with the current printer setup” as soon as I hit OK in the Print dialogue, with instructions to add a printer or set a default printer or check drivers) AND if I right click the 5100 in 'Printers and faxes' I get a warning that drivers are not installed (if I accept the invitation to install drivers, the process apparently completes successfully, but the problem is not solved – next time I right click it still says the drivers are not installed and I still can’t print; if in the printer properties dialogue I go to “Advanced” and select a different driver, apply it, then re-select the 5100 driver and hit apply, it loops back to the “printer driver is not installed on this computer” warning and asks me to install again).
So, in sum, the printer works, the USB cable and ports are OK, I have tried the latest software from Kodak and Apple's sites as well as the old software from the Kodak installation disk, the drivers are present, the Kodak software reports the printer connected, Windows told me my hardware was successfully installed, the printer shows in device manager…but somehow the drivers are still “not installed” when I try to print. Somehow, installing the drivers does not stick even though it appears they installed.
Any suggestions as to what to try next would be greatly appreciated.
Thanks for any help,
David
