ABSTRACT:
A paper cutting system for use with printer mechanisms, and more particularly to an apparatus and method for double cutting paper in a printer to trim the final output paper to a standard length. The invention provides an economical means for printing a full-size image on a standard length output sheet from a roll of paper by initially setting the length of the output sheet to the desired standard length plus the length of the necessary leading margin. After the image is printed full-size on the extra-length output sheet, the output sheet is advanced forward out of the printer and cut a first time by the printer's paper trimmer to crop the leading margin of the output sheet. The output sheet is then advanced forward again and cut a second time to crop the output sheet to the desired standard length size.
