IPrintOemUI COM Interface
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 IPrintOemUI COM interface is the means by which the printer interface DLL for Unidrv or Pscript5 communicates with a UI plug-in. The IPrintOemUI interface is implemented by each UI plug-in.
The following table lists and describes all the methods that the IPrintOemUI interface supplies. UI plug-ins must define all listed methods. If a method is not needed, it can simply return E_NOTIMPL.
| Method | Description |
|---|---|
| IPrintOemUI::CommonUIProp | Enables a UI plug-in to modify an existing printer property sheet page or document property sheet page. |
| IPrintOemUI::DeviceCapabilities | Enables a UI plug-in to specify customized device capabilities. |
| IPrintOemUI::DevicePropertySheets | Enables a UI plug-in to add a new page to a printer device's printer property sheet. |
| IPrintOemUI::DevMode | Performs operations on a UI plug-in's private DEVMODEW members. |
| IPrintOemUI::DevQueryPrintEx | Enables a UI plug-in to help determine if a print job is printable. |
| IPrintOemUI::DocumentPropertySheets | Enables a UI plug-in to add a new page to a printer device's document property sheet. |
| IPrintOemUI::DriverEvent | Called by the print spooler when processing driver-specific events that might require action by the printer driver. |
| IPrintOemUI::FontInstallerDlgProc | Replaces the Unidrv font installer's user interface. |
| IPrintOemUI::GetInfo | (Implementation required.) Returns a UI plug-in's identification information. |
| IPrintOemUI::PrinterEvent | Enables a UI plug-in to process printer events. |
| IPrintOemUI::PublishDriverInterface | (Implementation required.) Supplies a pointer to the Unidrv or Pscript5 driver's IPrintOemDriverUI COM interface, IPrintCoreUI2 COM interface, IPrintCoreHelperPS interface, or IPrintCoreHelperUni interface. |
| IPrintOemUI::QueryColorProfile | Enables a printer interface DLL to specify an ICC profile for color management. |
| IPrintOemUI::UpdateExternalFonts | Enables a printer interface DLL to update a printer's Unidrv font format files. |
| IPrintOemUI::UpgradePrinter | Enables a UI plug-in to upgrade device option values that are stored in the registry. |
