QPrinter ¶

概要 ¶

详细描述 ¶

This device represents a series of pages of printed output, and is used in almost exactly the same way as other paint devices such as QWidget and QPixmap . A set of additional functions are provided to manage device-specific features, such as orientation and resolution, and to step through the pages in a document as it is generated.

When printing directly to a printer on Windows or macOS, QPrinter uses the built-in printer drivers. On X11, QPrinter uses the Common Unix Printing System (CUPS) to send PDF output to the printer. As an alternative, the printProgram() function can be used to specify the command or utility to use instead of the system default.

Note that setting parameters like paper size and resolution on an invalid printer is undefined. You can use isValid() to verify this before changing any parameters.

QPrinter supports a number of parameters, most of which can be changed by the end user through a print dialog . In general, QPrinter passes these functions onto the underlying QPrintEngine .

The most important parameters are:

• setOrientation() 告诉 QPrinter which page orientation to use.

• setPaperSize() 告诉 QPrinter what paper size to expect from the printer.

• setResolution() 告诉 QPrinter what resolution you wish the printer to provide, in dots per inch (DPI).

• setFullPage() 告诉 QPrinter whether you want to deal with the full page or just with the part the printer can draw on.

• setCopyCount() 告诉 QPrinter how many copies of the document it should print.

Many of these functions can only be called before the actual printing begins (i.e., before begin() is called). This usually makes sense because, for example, it’s not possible to change the number of copies when you are halfway through printing. There are also some settings that the user sets (through the printer dialog) and that applications are expected to obey. See QAbstractPrintDialog ‘s documentation for more details.

当 begin() is called, the QPrinter it operates on is prepared for a new page, enabling the QPainter to be used immediately to paint the first page in a document. Once the first page has been painted, newPage() can be called to request a new blank page to paint on, or end() can be called to finish printing. The second page and all following pages are prepared using a call to newPage() before they are painted.

The first page in a document does not need to be preceded by a call to newPage() . You only need to calling newPage() after begin() if you need to insert a blank page at the beginning of a printed document. 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.

If you want to abort the print job, abort() will try its best to stop printing. It may cancel the entire job or just part of it.

Since QPrinter can print to any QPrintEngine subclass, it is possible to extend printing support to cover new types of printing subsystem by subclassing QPrintEngine and reimplementing its interface.

class QPrinter ( [ mode=ScreenResolution ] ) ¶

QPrinter(printer[, mode=ScreenResolution])

param printer

QPrinterInfo

param mode

PrinterMode

Creates a new printer object with the given mode .

Creates a new printer object with the given printer and mode .

PySide2.QtPrintSupport.QPrinter. PrinterMode ¶

This enum describes the mode the printer should work in. It basically presets a certain resolution and working mode.

常量	描述
QPrinter.ScreenResolution	Sets the resolution of the print device to the screen resolution. This has the big advantage that the results obtained when painting on the printer will match more or less exactly the visible output on the screen. It is the easiest to use, as font metrics on the screen and on the printer are the same. This is the default value. will produce a lower quality output than and should only be used for drafts.
QPrinter.PrinterResolution	This value is deprecated. It is equivalent to on Unix and on Windows and Mac. Due to the difference between and , use of this value may lead to non-portable printer code.
QPrinter.HighResolution	On Windows, sets the printer resolution to that defined for the printer in use. For PDF printing, sets the resolution of the PDF driver to 1200 dpi.

注意

When rendering text on a QPrinter device, it is important to realize that the size of text, when specified in points, is independent of the resolution specified for the device itself. Therefore, it may be useful to specify the font size in pixels when combining text with graphics to ensure that their relative sizes are what you expect.

PySide2.QtPrintSupport.QPrinter. 取向 ¶

This enum type (not to be confused with 取向 ) is used to specify each page’s orientation.

常量	描述
QPrinter.Portrait	the page’s height is greater than its width.
QPrinter.Landscape	the page’s width is greater than its height.

This type interacts with PaperSize and setFullPage() to determine the final size of the page available to the application.

PySide2.QtPrintSupport.QPrinter. PageOrder ¶

This enum type is used by QPrinter to tell the application program how to print.

常量	描述
QPrinter.FirstPageFirst	the lowest-numbered page should be printed first.
QPrinter.LastPageFirst	the highest-numbered page should be printed first.

PySide2.QtPrintSupport.QPrinter. ColorMode ¶

This enum type is used to indicate whether QPrinter should print in color or not.

常量	描述
QPrinter.Color	print in color if available, otherwise in grayscale.
QPrinter.GrayScale	print in grayscale, even on color printers.

PySide2.QtPrintSupport.QPrinter. PaperSource ¶

This enum type specifies what paper source QPrinter is to use. QPrinter does not check that the paper source is available; it just uses this information to try and set the paper source. Whether it will set the paper source depends on whether the printer has that particular source.

警告

This is currently only implemented for Windows.

常量	描述
QPrinter.Auto
QPrinter.Cassette
QPrinter.Envelope
QPrinter.EnvelopeManual
QPrinter.FormSource
QPrinter.LargeCapacity
QPrinter.LargeFormat
QPrinter.Lower
QPrinter.MaxPageSource	Deprecated, use instead

QPrinter.CustomSource	A defined by the printer that is unknown to Qt
QPrinter.LastPaperSource	The highest valid value, currently

PySide2.QtPrintSupport.QPrinter. PrinterState ¶

常量	描述
QPrinter.Idle
QPrinter.Active
QPrinter.Aborted
QPrinter.Error

PySide2.QtPrintSupport.QPrinter. OutputFormat ¶

The enum is used to describe the format QPrinter should use for printing.

常量	描述
QPrinter.NativeFormat	QPrinter will print output using a method defined by the platform it is running on. This mode is the default when printing directly to a printer.
QPrinter.PdfFormat	QPrinter will generate its output as a searchable PDF file. This mode is the default when printing to a file.

常量	描述
QPrinter.Millimeter
QPrinter.Point
QPrinter.Inch
QPrinter.Pica
QPrinter.Didot
QPrinter.Cicero
QPrinter.DevicePixel

Note the difference between Point and . The Point unit is defined to be 1/72th of an inch, while the unit is resolution dependant and is based on the actual pixels, or dots, on the printer.

PySide2.QtPrintSupport.QPrinter. DuplexMode ¶

This enum is used to indicate whether printing will occur on one or both sides of each sheet of paper (simplex or duplex printing).

常量	描述
QPrinter.DuplexNone	Single sided (simplex) printing only.
QPrinter.DuplexAuto	The printer’s default setting is used to determine whether duplex printing is used.
QPrinter.DuplexLongSide	Both sides of each sheet of paper are used for printing. The paper is turned over its longest edge before the second side is printed

PySide2.QtPrintSupport.QPrinter. numCopies ( ) ¶

返回类型

int

Returns the number of copies to be printed. The default value is 1.

On Windows, macOS and X11 systems that support CUPS, this will always return 1 as these operating systems can internally handle the number of copies.

On X11, this value will return the number of times the application is required to print in order to match the number specified in the printer setup dialog. This has been done since some printer drivers are not capable of buffering up the copies and in those cases the application must make an explicit call to the print code for each copy.

PySide2.QtPrintSupport.QPrinter. setFullPage ( arg__1 ) ¶

参数

arg__1 – bool

若 fp is true, enables support for painting over the entire page; otherwise restricts painting to the printable area reported by the device.

By default, full page printing is disabled. In this case, the origin of the QPrinter ‘s coordinate system coincides with the top-left corner of the printable area.

If full page printing is enabled, the origin of the QPrinter ‘s coordinate system coincides with the top-left corner of the paper itself. In this case, the device metrics will report the exact same dimensions as indicated by PaperSize . It may not be possible to print on the entire physical page because of the printer’s margins, so the application must account for the margins itself.
