How to enable Plugin Caching for PrintWhere - c06642353
With PrintWhere , when a user changes a destination printer, PrintWhere adds a helper printer object to the computer, referred to as a PrintWhere plugin. This plugin provides the computer access to the required printer driver. By default, to minimize its presence on the computer, PrintWhere uses only one plugin at a time. Whenever a user selects a different printer, PrintWhere removes the existing plugin and adds a new one.
To make these changes to the system, PrintWhere requires the user to have permission to change printers and set the drivers. If the user does not have permission to install drivers, then errors occur that can prevent the user from printing.
Plugin caching allows PrintWhere to maintain multiple plugins so that they don’t need to be removed and added every time the user selects a different printer. This approach allows users who cannot add new printers to work around their limited permissions. Users can move between the printers previously configured by the Administrator, since, from the system’s perspective, PrintWhere remains the selected destination printer. This is especially important in shared terminal environments.
To enable plugin caching:
- Open the Windows Registry Editor and navigate to the following Registry location: HKEY_LOCAL_MACHINE\Software\ PrinterOn Corporation\ PrintWhere
- In the right pane of the registry window, right-click and select New > DWORD value. The new value is added to the registry, with the name editable.
- Change the value name to PluginCacheEnabled .
- Right-click PluginCacheEnabled and click Modify. The Edit DWORD Value dialog appears.
- Set the Value data to 1.
- Close the Registry Editor.
