QPrinterInfo ¶

概要 ¶

详细描述 ¶

使用静态函数以生成列表为 QPrinterInfo 对象。每个 QPrinterInfo object in the list represents a single printer and can be queried for name, supported paper sizes, and whether or not it is the default printer.

static PySide2.QtPrintSupport.QPrinterInfo. availablePrinterNames ( ) ¶

返回类型

字符串列表

Returns a list of all the available Printer Names on this system.

It is recommended to use this instead of availablePrinters() as it will be faster on most systems.

Note that the list may become outdated if changes are made on the local system or remote print server. Only instantiate required QPrinterInfo instances when needed, and always check for validity before calling.

static PySide2.QtPrintSupport.QPrinterInfo. availablePrinters ( ) ¶

返回类型

Returns a list of QPrinterInfo objects for all the available printers on this system.

It is NOT recommended to use this as creating each printer instance may take a long time, especially if there are remote networked printers, and retained instances may become outdated if changes are made on the local system or remote print server. Use availablePrinterNames() instead and only instantiate printer instances as you need them.

PySide2.QtPrintSupport.QPrinterInfo. defaultColorMode ( ) ¶

返回类型

ColorMode

Returns the default color mode of this printer.

PySide2.QtPrintSupport.QPrinterInfo. defaultDuplexMode ( ) ¶

返回类型

DuplexMode

Returns the default duplex mode of this printer.

PySide2.QtPrintSupport.QPrinterInfo. defaultPageSize ( ) ¶

返回类型

QPageSize

Returns the current default Page Size for this printer.

static PySide2.QtPrintSupport.QPrinterInfo. defaultPrinter ( ) ¶

返回类型

QPrinterInfo

Returns the default printer on the system.

The return value should be checked using isNull() before being used, in case there is no default printer.

On some systems it is possible for there to be available printers but none of them set to be the default printer.
