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.
Setting the DIP Switches
By adjusting the settings of the two groups of DIP switches (SW1
and SW2) in the back of the printer, you can control various
features such as character set and page length.
To change the setting of a DIP switch, first turn off the printer.
Using a pencil, pen, or other pointed instrument, change the setting
as shown below. Then, turn the printer back on.
