Printing envelopes on HP Office Jet Pro 8600
FM 12, adv. I can't setup a layout to print center fed envelopes on the HP Office Jet Pro 8600. FM's instruction says the best way is to choose US Letter size paper in Print Setup. The setup looks good in the layout. But it doesn't work. When printing a "paper mismatch" occurs. The reason seems to be that the HP Office Jet checks the paper size before printing, recognizes the print setup is not to an envelope and shows the error. How can I configure the layout for #10 envelopes?
