Unidrv/PScript5 Driver Default DEVMODE Setup Behavior Changes

Important

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 the Print support app design guide.

A Unidrv/PScript5 driver that is running in XPSDrv mode creates the following driver default DEVMODE setup behavior changes.

In the following table, "PS only" means the behavior change is specific to a PScript5 driver. "Unidrv only" means the behavior change is specific to Unidrv driver. If both of these phrases don't appear, the behavior change applies to both Unidrv and PScript5 drivers.

Affected default DEVMODE fields	Non-XPSDrv behavior	XPSDrv behavior
dmFields: DM_ORIENTATION dmOrientation	Hard-coded to always set the DM_ORIENTATION flag in dmFields, and set dmOrientation = DMORIENT_PORTRAIT.	(Unidrv only) Only set the DM_ORIENTATION flag in dmFields if the GPD file supports the "Orientation" GPD feature. dmOrientation is set based on the "Orientation" GPD feature's default option that is specified in the GPD file. (PS only) Only set the DM_ORIENTATION flag in dmFields if the PPD file supports a feature with the "PageOrientation" Print Schema keyword. dmOrientation is set to DMORIENT_LANDSCAPE if that feature has the default option with the "Landscape" or "ReverseLandscape" Print Schema keyword. Otherwise, dmOrientation is set to DMORIENT_PORTRAIT.
dmFields: DM_SCALE	(Unidrv only) Hard-coded to never set the DM_SCALE flag in dmFields. (PS only) Hard-coded to always set the DM_SCALE flag in dmFields.	Only set the DM_SCALE flag in dmFields if GPD or PPD supports a feature with the "PageScaling" Print Schema keyword.
dmFields: DM_TTOPTION dmTTOption	Hard-coded to always set DM_TTOPTION flag in dmFields, and set dmTTOption = DMTT_SUBDEV.	If GPD or PPD supports a feature with the "PageDeviceFontSubstitution" Print Schema keyword and the feature has the default option with the "On" Print Schema keyword, set the DM_TTOPTION flag and set dmTTOption = DMTT_SUBDEV. Otherwise, if GPD or PPD supports a feature with the "PageTrueTypeFontMode" Print Schema keyword and one of the following: If the feature has a default option with the "DownloadAsOutlineFont" Print Schema keyword, then set the DM_TTOPTION flag and set dmTTOption = DMTT_DOWNLOAD_OUTLINE. If the feature has a default option with the "RenderAsBitmap" Print Schema keyword, then set the DM_TTOPTION flag and set dmTTOption = DMTT_BITMAP. If the feature has a default option with "Automatic", "DownloadAsRasterFont", or "DownloadAsNativeTrueTypeFont" Print Schema keyword, then set the DM_TTOPTION flag and set dmTTOption = DMTT_DOWNLOAD. Otherwise, the DM_TTOPTION flag is cleared in dmFields because the printer doesn't indicate that it supports TrueType font substitution or downloading.
dmFields: DM_NUP	Hard-coded to always set the DM_NUP flag in dmFields.	Only set the DM_NUP flag in dmFields if GPD or PPD supports a feature with the "JobNUpAllDocumentsContiguously or "DocumentNUp" Print Schema keyword.
dmFields: DM_COLOR	Hard-coded to always set the DM_COLOR flag in dmFields.	Only set the DM_COLOR flag in dmFields if GPD or PPD specifies that the printer is a color printer.
dmFields: DM_PRINTQUALITY, DM_YRESOLUTION	(Unidrv only) Hard-coded to always set the DM_PRINTQUALITY flag in dm****Fields. (PS only) Hard-coded to always set the DM_PRINTQUALITY and DM_YRESOLUTION flags in dmFields.
dmFields: DM_COLLATE	Hard-coded to always set the DM_COLLATE flag in dmFields, and set dmCollate = DMCOLLATE_TRUE.	Only set the DM_COLLATE flag in dmFields if GPD or PPD supports the "Collate" GPD or PPD feature. dmCollate is set based on the "Collate" GPD or PPD feature's default option that is specified in GPD or PPD.
dmFields: DM_ICMMETHOD, DM_ICMINTENT	(Unidrv only) Hard-coded to always set the DM_ICMMETHOD and DM_ICMINTENT flags in dmFields. (PS only) If PPD specifies that the printer is a color printer, set the DM_ICMMETHOD and DM_ICMINTENT flags in dmFields.	Never set the DM_ICMMETHOD or DM_ICMINTENT flags in dmFields.
dmFields: DM_DITHERTYPE	(Unidrv only) Hard-coded to always set the DM_DITHERTYPE flag in dmFields.	(Unidrv only) Never set the DM_DITHERTYPE flag in dmFields.
