information about how to change the paper width, see

Print density
Selectable from levels 1 to 7 (85%  115%).
Initial setting: level 4 (100%)
Depending on the paper type, it is recommended to set the print density as shown in the table
below for the best print quality.
Original Paper type
TF50KS-E, TF60KS-E, PD150R, PD160R, PD190R,
P220AGB-1, P350, AF50KS-E, KT55F20, KT48F20

When the print density level is increased, printing speed may be reduced.
Print speed
Selectable from levels 1 to 13 (Slow  Fast)
Initial setting: level 13
Depending on print conditions, such as print duty, print head temperature, and data
transmission speed, print speed is automatically adjusted, which may cause white lines due
to intermittent print (the motor sometimes stops). To avoid this, keep the print speed
constant by setting it lower, or set the transmission speed higher for the serial interface.
