PCL5 Watermarking
Last modified on 11 August 2020 02:33 PM

Some PaperCut customers have reported pages being printed blank or light gray when watermarking is enabled on certain PCL5 printers.

We belive this is due to problems with setting gray levels in PCL5 macros on these printers’ PCL5 interpreters

If you see this problem on your PCL5 printer then

Add the line

WatermarkPCL5NoGrayLevel=on

to your print-provider.conf and restart your print provider.

print-provider.conf is located in:

[app-path]/providers/print/[platform]

Please also report the problem to PaperCut tech support
