PPR SIZE CHK
When you select ON, the printer stops printing if the width of paper
loaded in the printer does not match the data width. When you
select OFF, the printer continues to print even if the paper width
does not match the data, and the printer may print beyond the
paper.
Note:
When you load the paper using the manual feed slot, select ON.
PPR ALIGN CHK
When you select ON, if the paper is not straight, PAPER NOT
STRAIGHT appears on the LCD and the printer stops printing.
When you select OFF, a paper align error does not occur even if
the printed data is out of range of the paper, and the printer
continues to print.
TIME OUT
The setting range is 30 to 300 seconds. If the cable of your printer
is unplugged or your printer hangs up for more than the set time
range, the print job is cancelled and the printer starts paper feed.
CUTTER ADJ
You can adjust the paper cutting position when printing with a
top and bottom margin of zero. This function prints cutter
adjustment patterns and you can select the appropriate cutting
position from them.
REFRESH MRGN
When you select ON, the printer cuts an extra print area after
borderless printing is used automatically.
