Unidrv Capabilities

Important

The modern print platform is Windows' preferred means of communicating with printers. We recommend that you use Microsoft's IPP inbox class driver, along with Print Support Apps (PSA), to customize the print experience in Windows 10 and 11 for printer device development.

For more information, see Modern print platform and the Print support app design guide.

The Universal Printer Driver (Unidrv) provides the following capabilities:

  • Support for all non-Postscript printers, using printer-specific Unidrv minidrivers that describe each printer's characteristics.

  • A Unidrv user interface, based on the TreeView control and property sheets, that is consistent for all printers, but is also modifiable for each printer's unique options.

  • A single Unidrv renderer that, along with the GDI graphics engine, converts Microsoft Win32 GDI calls from applications into printer commands that can be sent to the print spooler.
