Type: Automated Test


The INFGate tool checks the syntax in INF files for print and imaging device drivers.


INFGate is the tool that checks both printing and imaging INF files. INFGate checks syntax, format, and the validity of the INF file. The tool can be run on an installed printer or on a stand-alone INF file. If an installed printer is selected, the tool looks for an INF file for the specified printer, and then runs.

Creating Valid INFs for Virtual Printers

Virtual printers must specify a null hardware ID. To specify a null hardware ID, in the models-section-name of the device's INF file, add a second comma between the install-section-name and the compatible-id.
