IPrintOemUni3 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 IPrintOemUni3 COM interface contains all the methods of, and extends the capabilities of, the IPrintOemUni COM Interface and the IPrintOemUni2 COM Interface.
The following table lists and describes all of the methods provided by the IPrintOemUni3 interface. Rendering plug-ins must define all listed methods. If a method is not needed, it can simply return E_NOTIMPL.
| Method | Description |
|---|---|
| IPrintOemUni3::DownloadPattern | Enables a plug-in to download a pattern to a printer. |
| IPrintOemUni3::GetPDEVAdjustment | Enables a plug-in to override specific PDEV settings. |
| IPrintOemUni3::SetBandSize | Enables a plug-in to specify the desired band size on the printed output. |
