Remote Application Server - Universal printer filtering

A system administrator can control the list of client-side printer drivers which should be allowed or denied the Universal Printing redirection privileges.

Using this functionality you can:

• Avoid server resource overloading by non-useful printer redirection. Since the majority of users choose to redirect all local printers (this is default setting), a large number of redirected devices is created on the server which are not really used. It's mostly related to various paperless printers like PDFCreator, Microsoft XPS Writer, or various FAX devices.
   
• Avoid server instability with certain printers. There are some printers that might create server instability (spooler service component) and as the result deny printing services as a whole for all connected users. It is very important that the administrator has the ability to include such drivers to the "deny" list to continue running printing services.

To specify printer drivers in the Drivers section:

1. In the Mode drop-down list, select which printers should be allowed redirection from the following options:
   
   - Allow redirection of printers using any driver: (default) This option places no limitation on the type of driver a printer is using to use redirection privileges.
   
   - Allow redirection of printers using one of the listed drivers: Select this option and add the "allowed" drivers to the list. To add a driver, click the plus-sign icon and type the driver name.
   
   - Don't allow redirection of printers that use one of the listed drivers: This is probably the most useful option in the context of this feature. The printers that use drivers specified in the list will be denied redirection privileges. All other printers will be allowed to use redirection.
    
2. To delete a printer driver from the list, click the minus-sign icon.

Please make a note of the following:

• When adding a printer driver to the list, type the printer driver name, NOT the printer name.
   
• The driver names comparison is case insensitive and requires full match (no partial names, no wildcards).
   
• The settings that you specify on this tab affect the entire Site (not an individual server).
