Members

dmDeviceName

A zero-terminated character array that specifies the "friendly" name of the printer or display; for example, "PCL/HP LaserJet" in the case of PCL/HP LaserJet. This string is unique among device drivers. Note that this name may be truncated to fit in the dmDeviceName array.

dmSpecVersion

The version number of the initialization data specification on which the structure is based. To ensure the correct version is used for any operating system, use DM_SPECVERSION.

dmDriverVersion

The driver version number assigned by the driver developer.

dmSize

Specifies the size, in bytes, of the DEVMODE structure, not including any private driver-specific data that might follow the structure's public members. Set this member to sizeof (DEVMODE) to indicate the version of the DEVMODE structure being used.

dmDriverExtra

Contains the number of bytes of private driver-data that follow this structure. If a device driver does not use device-specific information, set this member to zero.

dmFields

Specifies whether certain members of the DEVMODE structure have been initialized. If a member is initialized, its corresponding bit is set, otherwise the bit is clear. A driver supports only those DEVMODE members that are appropriate for the printer or display technology.

The following values are defined, and are listed here with the corresponding structure members.

DUMMYUNIONNAME.DUMMYSTRUCTNAME.dmPaperLength

For printer devices only, overrides the length of the paper specified by the dmPaperSize member, either for custom paper sizes or for devices such as dot-matrix printers that can print on a page of arbitrary length. These values, along with all other values in this structure that specify a physical length, are in tenths of a millimeter.

DUMMYUNIONNAME.DUMMYSTRUCTNAME.dmPaperWidth

For printer devices only, overrides the width of the paper specified by the dmPaperSize member.

DUMMYUNIONNAME.DUMMYSTRUCTNAME.dmScale

Specifies the factor by which the printed output is to be scaled. The apparent page size is scaled from the physical page size by a factor of dmScale /100. For example, a letter-sized page with a dmScale value of 50 would contain as much data as a page of 17- by 22-inches because the output text and graphics would be half their original height and width.

DUMMYUNIONNAME.DUMMYSTRUCTNAME.dmCopies

Selects the number of copies printed if the device supports multiple-page copies.

DUMMYUNIONNAME.DUMMYSTRUCTNAME.dmDefaultSource

Specifies the paper source. To retrieve a list of the available paper sources for a printer, use the DeviceCapabilities function with the DC_BINS flag.

This member can be one of the following values, or it can be a device-specific value greater than or equal to DMBIN_USER.

DUMMYUNIONNAME.DUMMYSTRUCTNAME.dmPrintQuality

Specifies the printer resolution. There are four predefined device-independent values:

If a positive value is specified, it specifies the number of dots per inch (DPI) and is therefore device dependent.

DUMMYUNIONNAME.dmPosition

DUMMYUNIONNAME.DUMMYSTRUCTNAME2

DUMMYUNIONNAME.DUMMYSTRUCTNAME2.dmPosition

For display devices only, a POINTL structure that indicates the positional coordinates of the display device in reference to the desktop area. The primary display device is always located at coordinates (0,0).

DUMMYUNIONNAME.DUMMYSTRUCTNAME2.dmDisplayOrientation

For display devices only, the orientation at which images should be presented. If DM_DISPLAYORIENTATION is not set, this member must be zero. If DM_DISPLAYORIENTATION is set, this member must be one of the following values

Value Meaning
DMDO_DEFAULT The display orientation is the natural orientation of the display device; it should be used as the default.
DMDO_90 The display orientation is rotated 90 degrees (measured clockwise) from DMDO_DEFAULT.
DMDO_180 The display orientation is rotated 180 degrees (measured clockwise) from DMDO_DEFAULT.
DMDO_270 The display orientation is rotated 270 degrees (measured clockwise) from DMDO_DEFAULT.
 

To determine whether the display orientation is portrait or landscape orientation, check the ratio of dmPelsWidth to dmPelsHeight.

Windows 2000:  Not supported.

DUMMYUNIONNAME.DUMMYSTRUCTNAME2.dmDisplayFixedOutput

For fixed-resolution display devices only, how the display presents a low-resolution mode on a higher-resolution display. For example, if a display device's resolution is fixed at 1024 x 768 pixels but its mode is set to 640 x 480 pixels, the device can either display a 640 x 480 image somewhere in the interior of the 1024 x 768 screen space or stretch the 640 x 480 image to fill the larger screen space. If DM_DISPLAYFIXEDOUTPUT is not set, this member must be zero. If DM_DISPLAYFIXEDOUTPUT is set, this member must be one of the following values.

Value Meaning
DMDFO_DEFAULT The display's default setting.
DMDFO_CENTER The low-resolution image is centered in the larger screen space.
DMDFO_STRETCH The low-resolution image is stretched to fill the larger screen space.
 

Windows 2000:  Not supported.

dmColor

Switches between color and monochrome on color printers. The following are the possible values:

  • DMCOLOR_COLOR
  • DMCOLOR_MONOCHROME

dmDuplex

Selects duplex or double-sided printing for printers capable of duplex printing. Following are the possible values.

Value Meaning
DMDUP_SIMPLEX Normal (nonduplex) printing.
DMDUP_HORIZONTAL Short-edge binding, that is, the long edge of the page is horizontal.
DMDUP_VERTICAL Long-edge binding, that is, the long edge of the page is vertical.

dmYResolution

Specifies the y-resolution, in dots per inch, of the printer. If the printer initializes this member, the dmPrintQuality member specifies the x-resolution, in dots per inch, of the printer.

dmTTOption

Specifies how TrueType fonts should be printed. This member can be one of the following values.

Value Meaning
DMTT_BITMAP Prints TrueType fonts as graphics. This is the default action for dot-matrix printers.
DMTT_DOWNLOAD Downloads TrueType fonts as soft fonts. This is the default action for Hewlett-Packard printers that use Printer Control Language (PCL).
DMTT_DOWNLOAD_OUTLINE Downloads TrueType fonts as outline soft fonts.
DMTT_SUBDEV Substitutes device fonts for TrueType fonts. This is the default action for PostScript printers.

dmCollate

Specifies whether collation should be used when printing multiple copies. (This member is ignored unless the printer driver indicates support for collation by setting the dmFields member to DM_COLLATE.) This member can be one of the following values.

Value Meaning
DMCOLLATE_TRUE Collate when printing multiple copies.
DMCOLLATE_FALSE Do not collate when printing multiple copies.

dmFormName

A zero-terminated character array that specifies the name of the form to use; for example, "Letter" or "Legal". A complete set of names can be retrieved by using the EnumForms function.

dmLogPixels

The number of pixels per logical inch. Printer drivers do not use this member.

dmBitsPerPel

Specifies the color resolution, in bits per pixel, of the display device (for example: 4 bits for 16 colors, 8 bits for 256 colors, or 16 bits for 65,536 colors). Display drivers use this member, for example, in the ChangeDisplaySettings function. Printer drivers do not use this member.

dmPelsWidth

Specifies the width, in pixels, of the visible device surface. Display drivers use this member, for example, in the ChangeDisplaySettings function. Printer drivers do not use this member.

dmPelsHeight

Specifies the height, in pixels, of the visible device surface. Display drivers use this member, for example, in the ChangeDisplaySettings function. Printer drivers do not use this member.

DUMMYUNIONNAME2

DUMMYUNIONNAME2.dmDisplayFlags

Specifies the device's display mode. This member can be a combination of the following values.

Value Meaning
DM_GRAYSCALE Specifies that the display is a noncolor device. If this flag is not set, color is assumed.
DM_INTERLACED Specifies that the display mode is interlaced. If the flag is not set, noninterlaced is assumed.
 

Display drivers use this member, for example, in the ChangeDisplaySettings function. Printer drivers do not use this member.

DUMMYUNIONNAME2.dmNup

Specifies where the NUP is done. It can be one of the following.

Value Meaning
DMNUP_SYSTEM The print spooler does the NUP.
DMNUP_ONEUP The application does the NUP.

dmDisplayFrequency

Specifies the frequency, in hertz (cycles per second), of the display device in a particular mode. This value is also known as the display device's vertical refresh rate. Display drivers use this member. It is used, for example, in the ChangeDisplaySettings function. Printer drivers do not use this member.

When you call the EnumDisplaySettings function, the dmDisplayFrequency member may return with the value 0 or 1. These values represent the display hardware's default refresh rate. This default rate is typically set by switches on a display card or computer motherboard, or by a configuration program that does not use display functions such as ChangeDisplaySettings.

dmICMMethod

Specifies how ICM is handled. For a non-ICM application, this member determines if ICM is enabled or disabled. For ICM applications, the system examines this member to determine how to handle ICM support. This member can be one of the following predefined values, or a driver-defined value greater than or equal to the value of DMICMMETHOD_USER.

Value Meaning
DMICMMETHOD_NONE Specifies that ICM is disabled.
DMICMMETHOD_SYSTEM Specifies that ICM is handled by Windows.
DMICMMETHOD_DRIVER Specifies that ICM is handled by the device driver.
DMICMMETHOD_DEVICE Specifies that ICM is handled by the destination device.
 

The printer driver must provide a user interface for setting this member. Most printer drivers support only the DMICMMETHOD_SYSTEM or DMICMMETHOD_NONE value. Drivers for PostScript printers support all values.

dmICMIntent

Specifies which color matching method, or intent, should be used by default. This member is primarily for non-ICM applications. ICM applications can establish intents by using the ICM functions. This member can be one of the following predefined values, or a driver defined value greater than or equal to the value of DMICM_USER.

Value Meaning
DMICM_ABS_COLORIMETRIC Color matching should optimize to match the exact color requested without white point mapping. This value is most appropriate for use with proofing.
DMICM_COLORIMETRIC Color matching should optimize to match the exact color requested. This value is most appropriate for use with business logos or other images when an exact color match is desired.
DMICM_CONTRAST Color matching should optimize for color contrast. This value is the most appropriate choice for scanned or photographic images when dithering is desired.
DMICM_SATURATE Color matching should optimize for color saturation. This value is the most appropriate choice for business graphs when dithering is not desired.

dmMediaType

Specifies the type of media being printed on. The member can be one of the following predefined values, or a driver-defined value greater than or equal to the value of DMMEDIA_USER.

Value Meaning
DMMEDIA_STANDARD Plain paper.
DMMEDIA_GLOSSY Glossy paper.
DMMEDIA_TRANSPARENCY Transparent film.
 

To retrieve a list of the available media types for a printer, use the DeviceCapabilities function with the DC_MEDIATYPES flag.

dmDitherType

Specifies how dithering is to be done. The member can be one of the following predefined values, or a driver-defined value greater than or equal to the value of DMDITHER_USER.

Value Meaning
DMDITHER_NONE No dithering.
