When printing on envelopes, be sure that your application

program settings keep the printing entirely within the

printable area of the envelopes as shown below.

To make sure that the printing fits within this area, always

perform a sample printing test using a normal single sheet
of paper before printing on envelopes.

features such as character set and page length.
