You can use the PrtDevMode property to set or return printing device mode information specified for a form or report in the Print dialog box.
Note It is strongly recommended that you consult the Win32 Software Development Kit for complete documentation on the PrtDevMode, PrtDevNames, and PrtMip properties.
The PrtDevMode property setting is a 94-byte structure that mirrors the DEVMODE structure defined in the Win32 Software Development Kit. For complete information on the PrtDevMode property members, consult the Win32 Software Development Kit.
The PrtDevMode property uses the following members.
|DeviceName||A string with a maximum of 32 bytes that specifies the name of the device the driver supports for example, "HP LaserJet IIISi" if the Hewlett-Packard LaserJet IIISi is the specified printer. Each printer driver has a unique string.|
|SpecVersion||An Integer that specifies the version number of the DEVMODE structure in the Win32 Software Development Kit.|
|DriverVersion||An Integer that specifies the printer driver version number assigned by the printer driver developer.|
|Size||An Integer that specifies the size, in bytes, of the DEVMODE structure. (This value doesn't include the optional dmDriverData member for device-specific data, which can follow this structure.) If an application manipulates only the driver-independent portion of the data, you can use this member to find out the length of this structure without having to account for different versions.|
|DriverExtra||An Integer that specifies the size, in bytes, of the optional dmDriverData member for device-specific data, which can follow this structure. If an application doesn't use device-specific information, you set this member to 0.|
|Fields||A Long value that specifies which of the remaining members in the DEVMODE structure have been initialized. It can be any combination of specific constants or none of them. For available constants, see the Fields member constants.|
|Orientation||An Integer that specifies the orientation of the paper. It can be either 1 (portrait) or 2 (landscape).|
|PaperSize||An Integer that specifies the size of the paper to print on. If you set this member to 0 or 256, the length and width of the paper are specified by the PaperLength and PaperWidth members, respectively. Otherwise, you can set the PaperSize member to a predefined value. For available values, see the PaperSize member values.|
|PaperLength||An Integer that specifies the paper length in units of 1/10 of a millimeter. This member overrides the paper length specified by the PaperSize member for custom paper sizes or for devices such as dot-matrix printers that can print on a variety of paper sizes.|
|PaperWidth||An Integer that specifies the paper width in units of 1/10 of a millimeter. This member overrides the paper width specified by the PaperSize member.|
|Scale||An Integer that specifies the factor by which the printed output will be scaled. The apparent page size is scaled from the physical page size by a factor of scale/100. For example, a piece of paper measuring 8.5 by 11 inches (letter-size) with a Scale value of 50 would contain as much data as a page measuring 17 by 22 inches because the output text and graphics would be half their original height and width.|
|Copies||An Integer that specifies the number of copies printed if the printing device supports multiple-page copies.|
|DefaultSource||An Integer that specifies the default bin from which the paper is fed. For available values, see the DefaultSource member values.|
|PrintQuality||An Integer that specifies the printer resolution. The values are 4 (high), 3 (medium), 2 (low), and 1 (draft).|
|Color||An Integer. For a color printer, specifies whether the output is printed in color. The values are 1 (color) and 2 (monochrome).|
|Duplex||An Integer. For a printer capable of duplex printing, specifies whether the output is printed on both sides of the paper. The values are 1 (simplex), 2 (horizontal), and 3 (vertical).|
|YResolution||An Integer that specifies the y-resolution of the printer in dots per inch (dpi). If the printer initializes this member, the PrintQuality member specifies the x-resolution of the printer in dpi.|
|TTOption||An Integer that specifies how TrueType fonts will be printed. For available values, see the TTOption member values.|
|Collate||An Integer that specifies whether collation should be used when printing multiple copies. Using uncollated copies provides faster, more efficient output, since the data is sent to the printer just once.|
|FormName||A string with a maximum of 16 characters that specifies the size of paper to use; for example, "Letter" or "Legal".|
|Pad||A Long value that is used to pad out spaces, characters, or values for future versions.|
|Bits||A Long value that specifies in bits per pixel the color resolution of the display device.|
|PW||A Long value that specifies the width, in pixels, of the visible device surface (screen or printer).|
|PH||A Long value that specifies the height, in pixels, of the visible device surface (screen or printer).|
|DFI||A Long value that specifies the device's display mode.|
|DFR||A Long value that specifies the frequency, in hertz (cycles per second), of the display device in a particular mode.|
You can set the PrtDevMode property using .
This property setting is read/write in Design view and read-only in other views.
Caution Printer drivers can add device-specific data immediately following the 94 bytes of the DEVMODE structure. For this reason, it is important that the DEVMODE data outlined above not exceed 94 bytes.
Only printer drivers that export the ExtDeviceMode function use the DEVMODE structure.
An application can retrieve the paper sizes and names supported by a printer by using the DC_PAPERS, DC_PAPERSIZE, and DC_PAPERNAMES values to call the DeviceCapabilities function.
Before setting the value of the TTOption member, applications should find out how a printer driver can use TrueType fonts by using the DC_TRUETYPE value to call the DeviceCapabilities function.
