Dmdevicename |
Specifies the name of the device supported by the driver. For example, for the PCL/HP LaserJet series, it will be a Cl/HP Laser printer. This string is different between the device drivers. |
Dmspecversion |
Specifies the version number of the initialization data. This structure is based on the data. |
Dmdriverversion |
Specifies the printer driver version number assigned by the printer driver developer. |
Dmsize |
Specifies the size of the devmode structure, in bytes, excluding dmdriverdata (device-related) members. If an application only operates on a part of the data that is not related to the driver, it can use this member to determine the length of the structure, without having to have records of different versions. |
Dmdriverextra |
Contains the number of private driver data after this structure, in bytes. If the device driver does not use the unique information of the device, set this member to zero. |
Dmfields |
Specify which of the remaining Members with the devmode structure have been initialized. The 0th-bit (defined as DM) orientation represents dmorientation, and the 1st-bit (defined as dm_papersize) represents dmpapersize. Printer Drivers appear to only support those that are suitable for printing technology. |
Dmorientation |
Select the direction of the paper. This member can be dmorient_portrait (1) or dmorient _ landscape (2 ). |
Dmpapersize |
Select the size of the paper to be printed. If the length and width of the paper are both set by the dmpaperlength and dmpaperwidth members, this member can be set to 0. Otherwise, the dwpapersize member can be set to one of the following values:

Dmpaperlength |
Redefines the length of the paper specified by the dmpapersize member. It can be used to customize the size of the paper, or for dot matrix printers, which can print any length of paper. These values and other specified physical length values in this structure are in the unit of 0.1mm. |
Dmpaperwidth |
Reload the width of the paper specified by the dmpapersize member. |
Dmscale |
Specifies the scaling factor of the output. The actual page size is the size of the physical paper multiplied by dmscale/100. For example, if the dmscale value is 50 for the paper of the letter size, it can accommodate content equivalent to 17 × 22 inch pages, because the width and height of the output text and image are half of the original size. |
Dmcopies |
If the device supports multi-page copying, select the number of copies to be printed. |
Dmdefaultsource |
Reserved. It must be 0. |
Dmprintquality |
Specifies the resolution of the printer. There are four predefined device-independent values: Dmres_high Dmres_medium Dmres_low Dmres_draft If a positive value is given, it specifies the number of points (DPI) printed per inch, so it is related to the device. |
Dmcolor |
For color printers, switch between color and monochrome. The following are possible values: · Dmcolor _ color · Dmcolor _ monochrome |
Dmduplex |
Select the dual-sided printing mode for printers that support double-sided printing. Possible values: · Dmdup _ Simplex · Dmdup _ horizontal · Dmdup _ vertical |
Dmyresolution |
Specifies the resolution of the printer in the Y direction, in the unit of points per inch. If the printer initializes the member, the dmprintquality Member specifies the resolution of the printer in the X direction, in the unit of points per inch. |
Dmttoption |
Specifies how to print the TrueType font. This member can take one of the following values:
· |
Dmtt_bitmap |
Print the TrueType font as a graph. This is the default action of the dot matrix printer. |
· |
Dmtt_download |
Download the TrueType font as a soft font. This is the default action for HP printers using the printer control language (PCL. |
· |
Dmtt_subdev |
Replace the device font with the TrueType font. This is the default action for postscript series printers. |
|
Dmcollate |
Check whether multiple copies are printed. When dmcollate_false is used, the output can be faster and more effective, because no matter how many copies are printed, data is transmitted only once to the printer. Only one page is printed after the printer is notified. This member can be one of the following values:
· |
Dmcollate_true |
Proofread when multiple copies are printed. |
· |
Dmcollate_false |
If multiple copies are printed, the system does not proofread them. |
|
Dmformname |
The format name to be used is specified. For example, letter or legal. The complete set of these names can be obtained through the windows enumforms function. |
Dmunusedpadding |
Used to align the structure to the DWORD boundary. This member cannot be used or referenced. Its name and usage are retained and may change in future versions. |
Dmbitsperpel |
Specifies the color resolution of the display device, in the unit of pixel digits. For example, use 4 digits for 16 colors, 8 digits for 256 colors, and 16 digits for 65536 colors. |
Dmpelswidth |
Specifies the width in pixels of the visible device surface. Dmpelsheight specifies the height of the visible device surface in pixels. |
Dmdisplayflags |
Specifies the display mode of the device. The following are valid symbols:
· |
Dm_grayscale |
Specifies that the display uses a non-color device. If this flag is not set, the color mode is assumed. |
· |
Dm_interlaced |
Specifies the display mode of the line. If this flag is not set, it is assumed that the non-interlaced mode is used. |
|
Dmdisplayfrequency |
Specify the frequency (the number of cycles per second) used by the display device in a specific mode in Hz ). |
