I just set up my new printer. It prints smaller sheets fine, but when i try to print a 24x36 drawing, I get an error message in the print dialog, "The specified custom paper size is not supported in selected tray"
I was trying to use the "manage custom sizes" selection in the paper size box in the print window. By going up to the "Super D" selection on paper sizes, there is an option to use "Super D on the roll" That solved my problem. HP is supposed to get back to me about using custom sizes from the roll.
