Enhanced Printing Options (CS2436-3)
Before printing, check how much of the roll paper is left. If you have activated
automatic detection of the remaining roll paper, a warning message is displayed
when there is not enough roll paper left.
If not much ink is left, prepare replacement ink tanks.
To print at a higher level of quality, in the printer driver, choose High or Highest
in Print Quality, and choose Unidirectional Printing as the direction of printing.
