Printing Specifications
NOTE: If the printing duty ratio is too high, the operation of the print head is stopped by the duty limit. In such
c ircumstances, the printing speeds shown above cannot be guranteed.
When select red-color or 2-colors(black and red) printing, the printing speed goes down compared with
black-color printing. It is caused by the switching operation in the printer.
