Known Issues with PaperCut v10
Version 10.0 build 9546
If the client software is started with the --minimized option and the account selection popup is enabled, in some rare situations the client may consume high CPU until the window is focused in the foreground. This issue only affects the Windows operating system. A patch is avaliable if required. The alternate solution is to temporarily remove the start --minimized option.
Web Print users may experience issues when printing PDF files generated in Open Office that have a Title added to the document properties. To work around this issue the author of the PDF can unselect Display document title under File -> Export PDF -> User Interface when creating the PDF document.
PaperCut on Debian Linux (netbase 4.39-4.40)
A change in the above Debian version update breaks networking in many applications. The PaperCut application server may fail to start and/or fail to accept connections (i.e. cannot access the web interface). There is contention over whether the change is a bug or the right thing to do. More information and a workaround (set net.ipv6.bindv6only=0) are available in this Debian bug report:
