This section describes the main restrictions of printer driver.
Usage Restrictions from the CUPS Operation Setting
The following restrictions are applied when you print with the CUPS driver:
1. If there is an error in the parameter for the specified option in the lpr command, the operation may be different depending on the option. The print job will be terminated forcibly without any warning if the option is other than PageSize, MediaType, or InputSlot.
[Example of an option parameter error (case in which job is not forcibly terminated)]
lpr -P IP4300 sample.ps -o MediaType=plan -o CNQuality=2
2. CUPS defaults to place an image at the center of the print area (unless the Custom Paper Size is specified for the Page Size) and enlarge the image including its margin as large as the print area if you print the image file directly with the lpr command or the cngpij command. The CNLocation option is applied to the image and margin which are expanded to the whole print area.
3. If you print an image file with the lpr command or the cngpij command, the image may be printed on the multiple pages. If such it the case, adjust the image size.
4. CUPS places a PostScript file at the bottom left corner of the print area and enlarges the file as defined by the PostScript file if you print the PostScript file with the lpr or cngpij command. If the size of the PostScript file is larger than the Page Size, the protruded area will not be printed.
