Appendix B Main Restrictions

This appendix describes the main restrictions of Print Filter.

§ Usage Restrictions Based on CUPS Operation Settings

When you use CUPS system to print data, the following restrictions apply:

  1. If an option is specified incorrectly, the operation differs depending on the option. For options other than "PageSize," "MediaType," and "InputSlot," the print job is forcibly terminated without warning.

    [Example of an option parameter error (case in which job is not forcibly terminated)]
     lpr -P PIXMAIP1500 sample.ps -o "MediaType=plan" -o "CNQuality=2"

  2. When you print an image file directly with the lpr command of CUPS and the default settings are used, CUPS centers the image in the print area and expands the image (including the margins) to the size of the print area. Therefore the "CNLocation" and "CNPercent" options apply to the expanded margins and image in the entire print area.

  3. When you print an image file directly with the lpr command of CUPS, the image may be divided and printed across several sheets of paper. If this happens, adjust the size of the image.

  4. When you print a Postscript file with the lpr command, CUPS positions that ps file at the bottom left corner of the print area and expands the file to the size defined in the ps file. If you try to print a ps file that is larger than the paper size, the parts that extend beyond the paper size are not printed.
