Page setup problem
My Page Setup paper size defaults to "Index card Letter 8.5 X 11in." (Does such a paper even exist?) I then click on this choice to change it to "US Letter," but this choice is available only under the "Index card Letter 8.5 X 11in." option. (The other options are "US Letter" and "US letter borderless.") No matter, as even after choosing "US letter" the "Index card Letter 8.5 X 11in" has once again appeared. I have also tried changing the default paper size in the Printers & Scanners Preferences pane, but US letter isn't even listed there, though US legal is. (!?!?)
Anyone have any suggestions?
I'm printing to an HP Deskjet Pro 8720.
