I cannot select the finest quality setting in the printer driver when using Mac OS X Snow Leopard (10.6). What can I do?


  • Driver settings: print quality
  • Stylus inkjet printers and All-In-One products
  • Mac OS X Snow Leopard (10.6)



If you are unable to select the finest print quality setting in the printer driver, try removing the printer driver. As Apple regularly deliver operating system and driver updates, we recommend installing the latest updates to ensure that you're using the latest printer driver version. These updates are delivered via Apple's Software Update utility.

Try the following:

  1. Power off the printer.

  2. Click the Spotlight icon in the upper-right corner of your screen. In the search field type Epson, then click Show All.

  3. Select all the files and folders with Epson in the name and drag them to the trash.

  4. Open your hard drive, select Library > Printers, the Epson folder and drag it to the trash.

    Caution Icon Caution:

    This removes all Epson printers.

  5. On your hard drive, select Users > Library > Preferences > Epson (/Users/Library/Preferences/Epson), select the files named[XXXXXXX].plist (XXXXXX represents any name) and then drag the files to the trash.

  6. From the Apple menu, select System Preferences and click Print & Fax.

  7. Press the Control and Apple button on your keyboard at the same time, then click anywhere in the printer list. Select Reset printing system....

  8. Click OK, when you see the prompt "Are you sure you want to reset the printing system?". An example of the screen is below:

    Resetting the printing system will remove all printers from the Printer list. You'll need to Add the printers you want again.

  9. Restart your Mac.

  10. Reinstall the Mac OS X 10.6.x upgrade. Download the latest system updates via the Apple menu > Software Update including any Epson printer driver updates such as the Epson Printer Drivers v2.1 for Mac OS X v10.6 package. The latest version is available on the Apple website:

  11. From the Apple menu, select System Preferences and then click Print & Fax.

  12. Power on the printer. Your Mac will add the printer automatically. If your printer does not appear automatically try the following:

    • Make sure you installed all the latest system updates, as described in the previous step. If there is a driver available for your printer in a later version of Mac OS X 10.6.x, your Mac will automatically add the printer when you turn the printer on.

    • Check if there is a Macintosh OS X 10.6.x driver available from the Drivers & Software page for your product on the Epson website. If driver version 8.07 or higher is available, download the driver and follow the on-screen installation instructions to install driver.

  13. If the printer has not been added automatically, click Add in Print & Fax and select the Epson printer from the list. Verify that 'Print Using' lists the printer name (without 'Gutenprint') and click Add.

  14. You can now attempt to print. When you next select Print and enter the Print Settings dialogue, you should be able to select the best print quality setting in Automatic and Advanced modes.
