Had this email from Epson and now all is well:
From the information you have provided, it would suggest that either a communication problem is present or the Mac is unable to display the EPSON driver in the Printer Browser.
It is recommended that all EPSON Printers are removed and re-installed.
To uninstall your printer:
1. Make sure that the EPSON printer is connected to the Mac through a direct USB connection (not through a Hub or the Keyboard) and switched on.
2. Make sure that the Mac is on and booted.
3. In the Mac Hard Drive/Applications/Utilities open the Printer Set-up Utility.
4. Remove all the references to the printer model.
5. Disconnect the printer from the computer.
6. We will now remove the EPSON Printer driver from the system and delete the drivers that you downloaded.
Go to the Mac Hard Drive/Library/Printer and move the complete EPSON folder to the trash. Warning this removes all EPSON Printers.
7. Also remove any drivers that were previously downloaded to the trash if the file name does not match that from our web site.
8. Restart the Mac.
9. Empty the trash.
10. Now we will run a repair utility that may take up to 30 minutes to complete so please plan for this. Go to Mac Hard Drive/Applications/Utilities and open the Disk Utility.
11. Select Disk First Aid at the top of the dialog box.
12. Select the Mac Hard Drive Icon in the left hand pane.
13. Select Repair Permissions at the bottom of the dialog box.
14. When this has completed restart the Mac. Power the printer on and ensure that it is directly connected to a USB port on the Mac and not via a third party device such as a USB hub.
You will now need to download the driver/s from the Epson website. Please connect to the Epson website via the link below:
http://esupport.epson-europe.com/SupportHome.aspx
Select your product type (i.e. All in One or Inkjet Printer) from the first drop-down menu, followed by the product model and your operating system (Mac OS X - Intel) from the other drop-down menu's, then click 'Search'. Download the printer driver for your printer and ensure this starts in the Download Manager. The file may be in a SIT format, which requires Stuffit Expander to expand the compressed files, if you have not installed Stuffit, it is available from:
http://www.stuffit.com/mac/expander
Please try the following to install and add the driver:
1. Locate the downloaded file, if in a SIT format, this requires Stuffit Expander so have Stuffit running.
2. If the file is a .DMG file, you do not require Stuffit, double-click the downloaded EPSON driver file and this will expand to reveal the dmg file and mounted drive.
3. Double-click the blue VISE icon when presented.
4. Follow the on screen prompts to install the driver, restarting the Mac when necessary.
5. Once restarted the driver needs adding to the printer list. To do this please go into the hard disk, go into the folder called Applications, double click on the folder called ‘Utilities’. You should see in this window the ‘Printer Setup Utility', double click on this icon. This will present the Printer List.
6. Delete any reference to the printer that may be on this list already as these may not be the genuine EPSON driver.
7. Click the add icon at the top and a dialogue box will appear, this will be the Printer Browser.
8. Next highlight the printer and then select add printer. Note: Do not choose a printer from the list of Epson printers. Your printer will not appear here, nor will the genuine Epson driver. You should be able to highlight the printer and choose 'Add'. If 'Add' is not available, leave the Printer Browser open and do not do anything else on the Mac, leave it open for about 10 minutes. When you come back to it, you should now find 'Add' available.
9. The printer should now be added to the printer list. Test the printer by highlighting it on the Printer List and selecting 'Utility'. The EPSON Printer Utility will appear, ensure paper is loaded and select to print a 'Nozzle Check'.
If you have an All in One, then to install the scanner component, locate the downloaded EPSON Scan driver and double-click this. The files will unstuff and a window will appear with the EPSON Scan Installer. Double-click this icon to initiate the installation.
11. Once installed, restart the Mac and the scanner should be ready to use. You can test this by going to: Applications : EPSON Scan.
