The QPrintEngine class defines an interface for how QPrinter interacts with a given printing subsystem.
The common case when creating your own print engine is to derive from both QPaintEngine and QPrintEngine. Various properties of a print engine are given with property() and set with setProperty().
This enum is used to communicate properties between the print engine and QPrinter. A property may or may not be supported by a given print engine.
Constant | Value | Description |
---|---|---|
QPrintEngine.PPK_CollateCopies | 0 | A boolean value indicating whether the printout should be collated or not. |
QPrintEngine.PPK_ColorMode | 1 | Refers to QPrinter.ColorMode, either color or monochrome. |
QPrintEngine.PPK_Creator | 2 | A string describing the document's creator. |
QPrintEngine.PPK_Duplex | 21 | A boolean value indicating whether both sides of the printer paper should be used for the printout. |
QPrintEngine.PPK_DocumentName | 3 | A string describing the document name in the spooler. |
QPrintEngine.PPK_FontEmbedding | 19 | A boolean value indicating whether data for the document's fonts should be embedded in the data sent to the printer. |
QPrintEngine.PPK_FullPage | 4 | A boolean describing if the printer should be full page or not. |
QPrintEngine.PPK_NumberOfCopies | 5 | Obsolete. An integer specifying the number of copies. Use PPK_CopyCount instead. |
QPrintEngine.PPK_Orientation | 6 | Specifies a QPrinter.Orientation value. |
QPrintEngine.PPK_OutputFileName | 7 | The output file name as a string. An empty file name indicates that the printer should not print to a file. |
QPrintEngine.PPK_PageOrder | 8 | Specifies a QPrinter.PageOrder value. |
QPrintEngine.PPK_PageRect | 9 | A QRect specifying the page rectangle |
QPrintEngine.PPK_PageSize | 10 | Obsolete. Use PPK_PaperSize instead. |
QPrintEngine.PPK_PaperRect | 11 | A QRect specifying the paper rectangle. |
QPrintEngine.PPK_PaperSource | 12 | Specifies a QPrinter.PaperSource value. |
QPrintEngine.PPK_PaperSources | 22 | Specifies more than one QPrinter.PaperSource value. |
QPrintEngine.PPK_PaperSize | PPK_PageSize | Specifies a QPrinter.PaperSize value. |
QPrintEngine.PPK_PrinterName | 13 | A string specifying the name of the printer. |
QPrintEngine.PPK_PrinterProgram | 14 | A string specifying the name of the printer program used for printing, |
QPrintEngine.PPK_Resolution | 15 | An integer describing the dots per inch for this printer. |
QPrintEngine.PPK_SelectionOption | 16 | |
QPrintEngine.PPK_SupportedResolutions | 17 | A list of integer QVariants describing the set of supported resolutions that the printer has. |
QPrintEngine.PPK_SuppressSystemPrintStatus | 20 | Suppress the built-in dialog for showing printing progress. As of 4.1 this only has effect on Mac OS X where, by default, a status dialog is shown. |
QPrintEngine.PPK_WindowsPageSize | 18 | An integer specifying a DM_PAPER entry on Windows. |
QPrintEngine.PPK_CustomPaperSize | 23 | A QSizeF specifying a custom paper size in the QPrinter.Point unit. |
QPrintEngine.PPK_PageMargins | 24 | A QList<QVariant> containing the left, top, right and bottom margin values. |
QPrintEngine.PPK_CopyCount | 25 | An integer specifying the number of copies to print. |
QPrintEngine.PPK_SupportsMultipleCopies | 26 | A boolean value indicating whether or not the printer supports printing multiple copies in one job. |
QPrintEngine.PPK_CustomBase | 0xff00 | Basis for extension. |
This method is abstract and should be reimplemented in any sub-class.
Instructs the print engine to abort the printing process. Returns true if successful; otherwise returns false.

Instructs the print engine to start a new page. Returns true if the printer was able to create the new page; otherwise returns false.
