Printer Font Descriptions
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 GPD language provides entries for describing hardware-resident fonts, font cartridges, and font substitution of TrueType fonts for similar hardware-resident or cartridge fonts.
You can optionally provide customized code for handling soft fonts. For information about this customized code, see Customized Font Management.
