Xojo printersetup4/16/2023 ![]() Printing occurs at HorizontalResolution, so you should always check and use that value after setting this value. After calling ShowPageSetupDialog, OpenPrinter, or ShowPrinterDialog, the HorizontalResolution property will automatically be set to the highest resolution supported by the printer driver, within your specified constraints, although this may be less than what you have specified. You can change it to the maximum printer resolution you're prepared to handle or -1 for the highest possible resolution of the output device. Set to request the maximum horizontal resolution for the printer to use. Var settings As String Var p As PrinterSetup p = New PrinterSetup If p. This example sets the Landscape property. Currently supported on Windows and macOS only. It is True for the landscape orientation False otherwise. Gets and sets the landscape state of the PrinterSetup object. Since PageLeft and PageTop are the horizontal and vertical margins as measured from the printable area rather than the edge of the page, they are negative. Results, of course, depend on the page size that the user selects. ![]() This example displays the Page Setup box and then displays the page size, printable area, and margins in Label controls. The horizontal resolution in dots per inch of the output device (usually a printer). Reporting bugs and making feature requests.Maximumhorizontalresolution and maximumverticalresolution.PPS: The WindowsDeviceModeMBS class in MBS Win Plugin can help to convert from ANSI to Unicode and back if needed. PS: If SetupString odes not start with "DoNotAlterThis=SetupString.2" or you are not on TargetWindows, you should not touch it as that may be a new future format. Implementing the proper function to test a setup string is left as homework to the reader. Skipping two bytes the next two bytes should be &hDC &h00 for Xojo 2017r2 and &h9C &h00 for Xojo 2016r3. But if you find it, you look in the binary data, if you find the bytes &h01 and &h04 exactly 32 or 64 bytes after the start of the binary data. from a new PrinterSetup object and you can simply use it. If you don’t have it, this is an incomplete setup string, e.g. To detect the format of a setup string, you can do the following: You find the string DevModeStructurePS= in the setup string. If you sum it up, you get &h054C and &h50C, which are exactly the sizes above. The next number is the driver’s data size in bytes, e.g. This value can be &h00DC for size of DEVMODEW structure for Xojo 2017r2 and &h009C for size of DEVMODEA structure for Xojo 2016r3. The following field is the size of the structure, not including any private, driver-specified data. Followed is the spec version &h0401 for Windows 2000 and newer. In the byte stream you see first 32 characters in both versions, either unicode (64 bytes!) or ANSI text. Please note the format can be printer specific and change depending on which fields are checked in the printer dialog! Values are for example 1292 for older format and 1356 for newer format of the same printer. One of the values listed is DevModeStructureSizePS which shows the size of the binary data. While the exact format of SetupString is not published, you can see it’s text with an embedded binary part. Sadly Xojo missed to increment the version number in their string to ignore older setup strings automatically! ![]() You run into problems if you use an older SetupString with newer Xojo versions. Xojo 2016r4 and newer use the unicode version. Xojo 2016r3 and older use DEVMODE structure to describe the printer setup in the ANSI version. Detect PrinterSetup data format As you may know Xojo 2016r4 to 2017r2 made a move to use DirectDraw for printing. ![]()
