About MyPrint and Mac OSX 10.7 (Lion)

If you recently installed Mac OS 10.7 (Lion) over an existing system in which MyPrint printers were already installed, you could find that those pre-existing printers no longer function properly. You can resolve the issue by removing the ad\ from your Keychain. However, if that doesn’t solve the problem, you should delete the printer(s) and set them up again, following the instructions for OS X on the Using MyPrint page.
