I have a new HP 6520 connected by USB to a machine running XP. I have been attempting to print some photos on 6 x 4 glossy paper loaded in the photo tray, printing from MS Photo Editor or from MS Picture manager (tried both). i have selected the settings 4x6 and various paper type settings with no difference to the behaviour it manfests.
In every instance the printer pulls in the photo tray, makes a noise as if the print head is about to print and the ejects the paper unprinted and throws up to error message "paper mismatch". I can find no settings in the "properties" which make any difference to this and nothing in the various forums i have searched gives a solution.
