Dane D:
I've been through the process with a couple of different Epson printers and this technique worked. You have to completely remove any references to your printers then reinstall the drivers:
Please follow the steps below to completely remove and reinstall a
downloaded driver for your printer in OSX.4
DEVICE REMOVAL
1. *Open the MAC HARD DRIVE, APPLICATIONS folder, UTILITIES folder, PRINTER
SETUP UTILITY.
2. *Highlight any listings of the Epson drivers and select DELETE.
3. *Close the PRINTER SETUP UTILITY.
REMOVE FILES
1. *Double click on the MAC HARD DRIVE.
2. *Double click on the LIBRARY folder.
3. *Double click on the PRINTERS folder.
4. *Drag the EPSON folder to the trash can.
*NOTE* If you receive an access denied error message, this indicates that
you do not have root access. You will need to contact Apple for assistance
on obtaining Root Access.
5. *Close any open windows.
6. *Double click on the MAC HARD DRIVE.
7. *Double click on the LIBRARY folder.
8. *Double click on the RECEIPTS folder.
9. *Delete any Epson Receipts.
10. Close all windows that are open, and restart your computer.
NOTE: The following procedure will remove all printers that you have
installed on your computer. If you have multiple printers on your system,
you will need to re-add all your printers once this is complete.
1. Make sure that your printer is turned on and connected to your computer.
2. Open the HARD DRIVE, go into the APPLICATIONS, and select the UTILITIES
folder.
3. Double click on the PRINTER SETUP UTILITY. Click on the PRINTER SETUP
UTILITY Menu option at the top of the screen and click on RESET PRINTING
SYSTEM. Click on RESET when prompted and then enter your system password.
This will remove all printer drivers in the list and you will have to add
all of them again.
