How to check that the correct driver is installed when experiencing printing issues in Mac OS X 10.5 - 10.11
Mac OS X Leopard (10.5), Snow Leopard (10.6), Lion (10.7), Mountain Lion (10.8), Mavericks (10.9), Yosemite (10.10), El Capitan (10.11)
Printer driver version
Limited driver options
Ink Level status unavailable
You may experience problems using your printer such as faint printouts, limited or missing print options, or no ink level status if you are using a Gutenprint driver.
If you have been experiencing such problems since upgrading to OS X Leopard (10.5), Snow Leopard (10.6), Lion (10.7), Mountain Lion (10.8), Mavericks (10.9) or Yosemite (10.10) attempting to install the Epson printer driver, the Epson printer driver may not be in use.
Follow the advice below, as appropriate for the Mac OS version running on your Macintosh computer.
How to check if the correct driver is being used for your printer
Follow these steps to check if you're using the Gutenprint driver and change it if necessary.
Click on the Apple icon then click on System Preferences.
The added drivers are listed on the left. Check the list for your Epson printer.
If your Epson printer is listed, click on the printer to highlight it and the driver information will appear in the pane on the right. Look beside Kind.
If you see only your printer's name, you're using the correct driver and you can skip the remaining steps.
The Epson Stylus Photo RX620 appears in the example below, but you will see your printer or All-In-One name instead
If you upgraded from driver version 3.x to 6.x, check that you are using the correct version. Click on the Options & Supplies button, and under the General tab you will find the printer's Driver Version. Verify that the driver version is correct e.g. 6.10, 6.12.
If you see Gutenprint next to your printer name, the correct driver is not being used. This is often the cause of printing-related issues, as you may be experiencing. Click on the incorrect Epson printer entry to highlight it then click on Delete. Then proceed to the section below.
How to add the correct driver for your printer
If the Epson driver is not listed, download and install it from the Epson Support website.
Once restarted, the printer driver may need to be added to Print & Fax / Print & Scan / Printers & Scanners. Normally, USB printers will add themselves automatically but this will need to be checked.
Open System Preferences then open Print & Fax / Print & Scan / Printers & Scanners.
Check the list for your printer.
If listed, click on the printer name to highlight it.
The driver information will appear on the right. Under 'Kind' the printer name should be listed, e.g. 'Epson Stylus xxxx' (where 'xxxx' is your printer model name).
The correct Epson driver should not have the name of another printer nor feature 'Gutenprint' or 'CUPS' in the version or under Kind.
If the correct driver has been added, move to Step 4.
If it appears that the correct Epson driver is not listed in Print & Fax / Print & Scan / Printers & Scanners, click on the printer entry to highlight it then click on Delete. Move to Step 3.
Attempt to add the correct printer driver to Print & Fax / Print & Scan / Printers & Scanners.
Click Add from the bottom of the printer window.
The window that will appear first will be the Printer Browser.
Connected printers with a valid driver installed should appear.
Shared printers: When adding a shared printer, always consult the Mac OS X and Apple documentation.
FireWire, AppleTalk, or TCP/IP printers: If you are using the printer via FireWire, AppleTalk, or TCP/IP (AppleTalk or TCP/IP if you use an Epson print server or Epson Network Interface Card):
Click on More Printers.
Another window will open, click on the pull-down menu and click on either EPSON TCP/IP, EPSON AppleTalk or EPSON FireWire, as appropriate.
Click on the Epson printer to highlight it and click on Add.
USB printers: If you are using the printer via USB:
Do not click on More Printers. Instead, click on the printer name in the list to highlight it and click the Add button.
Do not choose a different model from the list of printers that may be present.
If the Add button is greyed out, leave the Printer Browser open for 10 minutes and ensure that the printer is powered on and connected directly to the Mac. Do not connect it via a third party device such as a USB extension cable, an external USB hub or a USB port in a keyboard.
If you add a printer and see "Driver not installed", you may need to specify the type of printer you are using.
Try to add the printer again but do not add a Gutenprint driver.
When you see the Add Printer dialogue, select the driver to use from the Print Using / Use menu.
The printer should now be added to the printer list in Print & Fax / Print & Scan / Printers & Scanners. Check that you can see the name of the printer only and not 'Gutenprint' in the Kind.
Ensure that the paper size you use most regularly is set as the Default Paper Size. We recommend setting 'A4' as opposed to the default 'US Letter'.
To test the printer, attempt to print a nozzle check from the Epson Printer Utility.
Ensure plain A4 paper is loaded.
In Print & Fax / Print & Scan / Printers & Scanners, double-click the printer name.
10.5 - 10.6: Click on Utility from the top of the window.
10.7 - 10.10: Click on Printer Setup / Settings from the top of the window and select the Utility tab. Click Open Printer Utility.
In the Epson Printer Utility click on Nozzle Check.
If this is successful, the printer is ready to use. Try to print from Text Edit (found in Applications) to check if printing from an application that is native to OS X is possible.
