Printing multiple unwanted copies of JPG and TIF

What application are you printing from? Does it happen with all applications, or only one?

Please read this whole message before doing anything.

This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.

The purpose of this test is to determine whether the problem is localized to your user account. Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”

While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.

Test while logged in as Guest. Download a suitable image from the web. Same problem?

After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.

*Note: If you’ve activated “Find My Mac” or FileVault in OS X 10.7 or later, then you can’t enable the Guest account. The "Guest User" login created by "Find My Mac" is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.

If Photoshop is the only application involved in the problem, then something in your Photoshop settings is probably causing it. You should be able to find instructions on the Adobe website to reset the app. If that doesn't work, try the following.

Back up all data.

Triple-click anywhere in the line below on this page to select it:

~/Library/Preferences

Right-click or control-click the line and select

Services ▹ Open

from the contextual menu.* A folder named "Preferences" should open. Inside it are one or more files with names beginning in "com.apple.print." Move those files to the Desktop, leaving the folder open. If any print queues are open, quit them. Test. If there's no change, put the files you moved back, overwriting the ones that may have been created in their place. Otherwise, delete the files you moved and recreate your print settings, if necessary.

*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select

Go ▹ Go to Folder...

from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.
