Thanks for the reply. Yes, I was referring to those instructions.
I did print a photo directly from a memory card, and it looked fine. No lines, color ok, etc.
The test page from the printer was crisp, and the color blocks were perfect. As I said, the problem is only with photo printing. Documents are fine.
Being rather technically ignorant, can you give me an idea of how to check the software I'm printing from? As I recall, I simply installed the printer according to instructions and started printing. But that was about 2 years ago.
Thanks again!
