050 printer.
1.4.1 DIP Switch Settings
The DIP switches are located at the right side of the printer. When the printer hardware is initialized,
the following functions are set to the default values shown in the table below.

User-defined characters are maintained in printer memory even when the power is turned off,
so the user-defined character set can be easily selected simply by turning off the power, setting
this switch to ON, and then turning the power on again.

switches 1-6, 1-7, and 1-8 are different when using the printer in the IBM
emulation mode.

When print operation has finished, the short tear-off feature automatically feeds the perforation
of the continuous paper to the tear-off edge of the sheet guide cover so that the user can tear
off the last sheet. When the user resume printing, the paper is fed backward to the loading
position.
