Recommended setting
Maximum paper reduction
The table below shows the details of “Recommended setting, and “Maximum paper reduction.
Depending on print conditions, such as print duty, thermal 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.
To change the paper width, you need to install the 58 mm width paper guide plate. (See
"Changing the Paper Width" on page 40.)
B
ecause some parts of the print head and the autocutter contact the platen and they may
become worn out, once you change the paper width from 80 to 58 mm {3.15 to 2.28"} and use
the printer, you cannot change it back to 80 mm {3.15"}.

they are properly read by a barcode reader that is actually used.
