PaperCut NG 18.0.4 (Build 43117)
Posted by Apposite Solution Limited on 28 February 2018 11:09 AM

This is a Maintenance Release for 18.0 and contains the following changes:


  • Tuned Java parameters to improve Application Server performance on large sites.
  • Pay Station: When a Pay Station fails to connect to the Application Server to update a user's balance, the Pay Station now displays an error message and prints a transaction error report (if an acknowledgement printer is attached), so the user has proof that the transaction did not succeed.


  • Added a new Admin Right to control access to the Sites tab in the Admin interface.
  • Reduced the CreateSSLKeystore default certificate validity duration to not exceed 2038, to safeguard older devices running into a 2038 date rollover issue.
  • macOS High Sierra (CUPS): Reduced the time it takes for a printer to be available in the Control Printer Monitoring.command script.
  • Standard Release station via Site Server: Fixed an issue that caused an empty print release list for Hold/Release queue managers.
  • User Client:
    • Fixed an issue that prevented the User Client from launching when the User Client icon was double-clicked in the Windows task tray.
    • Fixed an issue that caused high memory usage, especially when a high number of shared accounts are used.
    **Note: User Clients require an upgrade.
  • Web Print:
    • Fixed an issue that caused the "Maximum document/file upload size" value to be ignored and set to 256MB instead.
    • Sandbox mode: Fixed an issue that caused multiple print jobs to be generated for each Web Print job in some virtual environments.
    ***Note: Web Print sandbox servers require an upgrade.
  • Google Cloud Print:
    • Fixed a rare issue that caused a Google Cloud Print job to be printed multiple times.
    • Fixed an issue that sometimes prevented PaperCut MF from publishing all printers to Google Cloud Print when there were a large number of printers.
  • Printer compatibility improvements:
    • RISO ComColor with PaperCut Global Print Driver: Added a new PDL transform to fix an issue that caused the printed output to have incorrect settings when printing in duplex, color, or selecting specific tray settings.
    • Canon printers on Linux and MacOS: Fixed an issue that caused an incorrect number of copies and pages to be reported for some Canon devices when using CUPS printing.
    • Epson printers: Fixed an issue that caused an incorrect number of copies and pages to be reported for some Epson printers.
    ****Note: Secondary servers require a Print Provider upgrade.

For Integrators:

  • On demand Payment Gateway API: Extended the API to support external lookup on different user properties, for example card ID or alias.

Other Notes:

  • If you are running v17.2.1 or later, there is NO database upgrade.
  • Fixes and enhancements marked with:
    • ** require a User Client upgrade.
    • *** require a Web Print server upgrade.
    • **** require a Print Provider upgrade.
