Hi. Thank you for the help. In answer to your question, it was a cleanly installed operating system. I chose what I thought would be the easiest fix - to download an alternate driver, the Deskjet 450. This fixed my problem on printing 4 x 6 photos and appears to be working for 8 1/2 x 11 also. I accepted this as a solution to the problem and have left Kudos.
One last question - with the original driver software, I was able to print a test page showing colors in various degrees as a test of the condition of the print color cartridges. This feature is not available in the 450 driver. Any suggestions?
Again - thank you.
