HP Envy Photo 7155. Windows 10 - I get "Photo tray was changed because of a conflict with another printer setting" on the computer or "The paper size detected by the printer is smaller than the paper size selected for the print job. The current print job will be canceled" on the small screen on the printer. I can printer a photo from the paper tray but I to tell it I am using a 3-1/2 x 5 photo paper and it comes out with a border. I was able to print "normally" a couple of months ago, but not now. Thanks for your help.
