Cannot Access Printer List in SENTINEL CODESOFT Printing Plug-In – SENTINEL Problem

Target Audience: Advanced User, IT Manager
Article #: 11976


SENTINEL appears to be missing printers and ports. However, print jobs sent to the “missing printers” still work and function normally. We noticed that the Print Spooler service was stopped. This prevented SENTINEL from being able to access the printer list in that file.

Situation and Symptoms

  • User is running SENTINEL 2015.
  • Web Services will not allow the Add Printer function.
  • The printing functions of the “missing” printers still work normally.
  • The Printer list and Ports do not appear when opening the CODESOFT Printing Plug-In
  • CODESOFT’s Printing Plug-In shows “License for 0 printers, 0 selected” at the bottom of the screen.


CODESOFT needs to access a specific XML file in order to perform certain functions. This file is C:\Users\Public\Public Documents\Teklynx\SENTINEL\tkxcs.xml. However, the stopped Print Spooler services blocks access. In this case, the print spooler was not only stopped, but set to “Disable” as well. A recent Windows update may be the cause.

The solution to allowing access to the printer list is straightforward. Setting the Print Spooler back to Automatic and then starting it resolves this issue. The Printer and Ports list repopulates and functions such as “Add Printer” work again.
