•
To change the paper width, you need to install the 58-mm width paper guide plate and to
make the paper width setting with the memory switch. For information about how to
change the paper width, see
"Changing the Paper Width" on page 36 .
•
Because 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 and use the
printer, you cannot change it back to 80 mm.
Printing speed may be slower, depending on the such items as the data transmission
speed.
