Devmode Structure Printer Drivers

If you are truly using raw printer output, OpenPrinter etc, then changing DEVMODE will not have any effect, you are bypassing the printer driver. It is then completely up to you to rotate output. Quite painful if the printer itself doesn't support it. The kind where bypassing the driver makes sense never do. – Hans Passant Mar 18 '13 at 15:24.

Only be used to set printer model specific features, like stapler, etc. The Windows API 'DevMode' structure is used by Windows and the Printer Driver to define the printer setup. The name DevMode is short for DeviceMode.-Nard Moseley Digital Metaphors www.digital-metaphors.com.
Foxit Quick PDF Library uses the standard Windows DEVMODE structure for printing which is used by many other programs as well. Unfortunately the printer driver manufacturers don’t use the values specified in the DEVMODE structure and instead use custom undocumented values. This means that the SetupCustomPrinter function works for many drivers but not every driver.

The GS-DEVMODE-DATA resides in the GSPRTDEF.COB copybook. This copybook holds what Microsoft calls DEVMODE data (Device Mode data) which is used to pass data to the printer sub-system to set up the printer.

The PrintDlg API will invoke the Standard Printer Dialog, and return this information to you in this data structure. The OpenPrinter API and the PrintFile API will pass this data to the printer. You may make changes to this information by using any of the settings provided in 88 items below. You need to set only those that are of interest to you, and you can allow the rest to default to the printer's default settings.

The definitions of the data names are below.

DMDEVICENAME

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

Specifies the version number of the initialization data specification on which the structure is based.

DMDRIVERVERSION

Specifies the driver version number assigned by the driver developer.

DMSIZE

Specifies the size, in bytes, of the DEVMODE portion of this structure, not including any auxiliary data that might follow.

DMDRIVEREXTRA

Contains the number of bytes of auxiliary driver-data that follow this structure. This may be zero.

DMFIELDS

Specifies whether certain items in structure have been initialized. If a field is initialized, its corresponding bit is set, otherwise the bit is clear.

DMORIENTATION

For printer devices only, selects the orientation of the paper. This field can be either DMORIENT-PORTRAIT (1) or DMORIENT-LANDSCAPE (2).

DMPAPERSIZE

For printer devices only, selects the size of the paper to print on. This field can be set to zero if the length and width of the paper are both set by the DMPAPERLENGTH and DMPAPERWIDTH fields. Otherwise, the DMPAPERSIZE field can be set to one of the following predefined values.

DMPAPERLENGTH

For printer devices only, overrides the length of the paper specified by the DMPAPERSIZE field, 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.

DMPAPERWIDTH

For printer devices only, overrides the width of the paper specified by the DMPAPERSIZE field.

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. nORMALLY SET TO 100.

DMCOPIES

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

DMDEFAULTSOURCE

Specifies the paper source. To retrieve a list of the available paper sources for a printer. This field can be one of the following values, or it can be a device-specific value greater than or equal to DMBIN-USER.

DMPRINTQUALITY

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

DMRES-HIGH
DMRES-MEDIUM
DMRES-LOW
DMRES-DRAFT

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

DMCOLOR

Switches between color and monochrome on color printers. 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 field, the DMPRINTQUALITY field specifies the x-resolution, in dots per inch, of the printer.

DMTTOPTIONS

Specifies how TrueType fonts should be printed. This field 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	Window 95/98/Me, Windows NT 4.0 and later: 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 field is ignored unless the printer driver includes support for collation. This field 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.

DMFORMSNAME

Windows NT/2000/XP: Specifies the name of the form to use; for example, 'Letter' or 'Legal'.

Windows 95/98/Me: Printer drivers do not use this field.

DMNUP

Specifies where the NUP is done. It can be one of the following. NUP = N Up, as in 3-up labels etc.

Value	Meaning
DMNUP-SYSTEM	The print spooler does the NUP.
DMNUP-ONEUP	The application does the NUP.

DMICMMETHOD

Windows 95/98/Me; Windows 2000/XP: Specifies how ICM is handled. For a non-ICM application, this field determines if ICM is enabled or disabled. For ICM applications, the system examines this field to determine how to handle ICM support. This field 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 field. Most printer drivers support only the DMICMMETHOD-SYSTEM or DMICMMETHOD-NONE value. Drivers for PostScript printers support all values.

CMICMINTENT

Windows 95/98/Me, Windows 2000/XP: Specifies which color matching method, or

Printer Driver Epson

intent, should be used by default. This field is primarily for non-ICM applications. ICM applications can establish intents by using the ICM functions. This field 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-COLORMETRIC	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

Windows 95/98/Me, Windows 2000/XP: Specifies the type of media being printed on. The field 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.

DMDITHERTYPE

Devmode Structure Printer Drivers

Windows 95/98/Me, Windows 2000/XP: Specifies how dithering is to be done. The field 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.
DMDITHER-COARSE	Dithering with a coarse brush.
DMDITHER-FINE	Dithering with a fine brush.
DMDITHER-LINEART	Line art dithering, a special dithering method that produces well defined borders between black, white, and gray scaling. It is not suitable for images that include continuous graduations in intensity and hue, such as scanned photographs.
DMDITHER-ERRORDIFFUSION	Windows 95/98/Me: Dithering in which an algorithm is used to spread, or diffuse, the error of approximating a specified color over adjacent pixels. In contrast, DMDITHER-COARSE, DMDITHER-FINE, and DMDITHER-LINEART use patterned halftoning to approximate a color.
DMDITHER-GRAYSCALE	Device does gray scaling.

DM-RESERVED

(just what it says)

The usage of DocumentProperties and SetPrinter API functions gives an opportunity to change the printer settings. But, when using them, I could not have a stable method of changing settings on all Windows OS versions. Below, all possible methods of changing printer parameters will be described and also the solution of how to obtain the stabler behavior for different Windows OS versions. In this article, I will describe the method of setting the printer settings and the problems I faced on different OS versions.

Changing Printer Settings

You can change the printer settings with the help of API:

DocumentProperties - retrieves and changes the printer parameters;
SetPrinter - determines data for printer, changes the state, and also can manage the printing and tasks.

Changing Settings Using the DocumentProperties Function

To use the DocumentProperties function to change the printer settings, you should do as follows:
