, \li setOrientation() tells QPrinter which page orientation to use. , \li setPaperSize() tells QPrinter what paper size to expect from the. , printer. On Windows or Mac OS X, QPrinter uses the built-in printer drivers. On X11, QPrinter generates postscript and sends that to lpr, lp, or another printProgram(). 30 Apr In the docs you’ll find QPrinter::printerState. So you can definitely do: if (printer. printerState() == QPrinter::Error) // do some error handling. I admit that’s not a lot.

See QAbstractPrintDialog’s documentation for more details. Landscape 1 the page’s width is greater than its height. A9 13 37 x 52 mm QPrinter:: This mode is the default when printing directly to a printer. This type interacts with QPrinter:: The programmer is responsible for reading this setting and printing accordingly.
B8 22 64 x 91 mm QPrinter:: This is how printing was traditionally done in Qt. The second page and all following pages are prepared using a call to newPage before they are painted.
QPrinter Class Reference
The orientation can be either QPrinter:: Returns the current state of the printer. Well, without seeing a bit of code it is going to be hard to say what’s wrong. Returns true if the print run was successfully aborted and printerState will return QPrinter:: It basically presets a certain resolution and working mode.
The default value is false.
Returns the printer options selection string. Returns the paper’s rectangle; this is usually larger than the pageRect. A set of additional functions are provided to qprniter device-specific features, such as orientation and resolution, and to step through the pages in a document as aprinter is generated. The default value is 1. Returns the current assumed resolution of the printer, as set by setResolution or by the printer driver. With setFullPage false the defaultthe metrics will be a bit smaller; how much depends on the printer in use.
That means the application has to handle the number of copies by printing the same document the required number of times.
Color qprinteer print in color if available, otherwise in grayscale. See also docName and QPrintEngine:: PaperSize paperSizeQPrinter:: Setting a non-empty name enables printing to a file. This is useful only if the print command has been explicitly set. See also setCopyCount and supportsMultipleCopies. A9 13 37 x 52 mm QPrinter:: Sets QPrinter to have the origin of the coordinate system at the top-left corner of the paper if fp is true, or where it thinks the top-left corner of the printable area is if fp is false.
If fromPage and toPage both return 0, this indicates that the whole document will be printed. The result is undefined if newPaperSize is not supported. This enum type specifies what paper size QPrinter should use. The page order can be QPrinter:: With collating turned on all pages are printed before the next copy of those pages is started.
A8 12 52 x qpriter mm QPrinter:: This is useful only if the print command has been explicitly set.
QPrinter Class | Qt Print Support
Note the difference between Point and DevicePixel. Of course, printing to PDF you might not have to worry about these. Many of these functions can only be called before the actual printing begins i.
The first page in a document does not need to be preceded by a call to newPage. Qprihter 0 the lowest-numbered page should be printed first.
There are also some settings that the user sets through the printer dialog and that applications are expected to obey. QPrinter does not check that the paper source is available; it just uses this information to try and set the paper source.
PageSize This enum type specifies what paper size QPrinter should use. Similarly, calling newPage after the last page in a document is painted will result in a trailing blank page appended to the end of the printed document. See QAbstractPrintDialog ‘s documentation for more details.
This can change the value of outputFormat. A1 6 x mm QPrinter:: Sets the printer paper size to newPaperSize if that size is supported. See QAbstractPrintDialog ‘s documentation for more details.
B0 14 x mm QPrinter:: This value will be changed by what the user presses in the print dialog.
