Preventing the remaining data from being printed on the second cut
sheet
If the print data size is larger than the maximum data size that can be
printed on a single sheet (manual feed/ ASF), the remaining data that
cannot be printed on the first sheet is not printed on the second sheet.
The remaining print data (graphic data) is ignored, and the next new
print data is printed from the top of the second paper.
