You can print on plain paper envelopes in 4 1/8 × 9 1/2 inch (#10) (105 × 241 mm) size.
Note:
Do not use envelopes that are curled or folded, and avoid using envelopes that are too thin because they may curl during printing. Before printing, select
Envelope as the paper type, select
Envelope #10 as the paper size, and
Landscape as the orientation.
