The Watermarking feature in PaperCut NG/MF generally works with standard print languages such as PostScript, PCL5, and PCL6. However, there are a few rare cases where watermarking doesn’t work as intended even when using one of these drivers. Fortunately these situations are easy to fix. See the list of limitations below:
- When the document spools in the EMF format which may occur if Advanced Print Features is enabled.
- When the document spools in the XPS format which may occur when Type 4 Print Drivers are used.
- “Full page” watermarking is not supported in conjunction with PCL5 content.
- UTF-8 languages such as Chinese, Japanese and Turkish are not supported, as languages (character sets) are limited to ASCII characters.
PaperCut watermarking currently assumes all pages in a document will have the same page size and orientation, so funny things can happen with mixed documents, and occasionally the watermark may print at the wrong location. Luckily, depending on the driver type there is usually an easy workaround.
- For PostScript, use a bottom of page watermark.
- For PCL5 and PCL6, use a top of page watermark. This is needed because the internal coordinate systems
for these languages have their page origins defined at the top left of each page.
