## Detailed Description

This class represents the Windows or PostScript printer, and is the vehicle through which printing may be launched by an application.

Printing can also be achieved through using of lower functions and classes, but this and associated classes provide a more convenient and general method of printing.

## Constructor & Destructor Documentation

wxPrinter::wxPrinter | ( | wxPrintDialogData * | data = `NULL` | ) |

Constructor.

Pass an optional pointer to a block of print dialog data, which will be copied to the printer object's local data.

## Member Function Documentation

virtual wxPrintAbortDialog* wxPrinter::CreateAbortWindow | ( | wxWindow * | parent,
|  | wxPrintout * | printout
| ) |  |
| virtual

Creates the default printing abort window, with a cancel button.

bool wxPrinter::GetAbort | ( |  | ) | const

Returns true if the user has aborted the print job.

static wxPrinterError wxPrinter::GetLastError | ( |  | ) |
| static

Return last error.

Valid after calling Print(), PrintDialog() or wxPrintPreview::Print().

These functions set last error to `wxPRINTER_NO_ERROR` if no error happened.

Returned value is one of the following:

wxPRINTER_NO_ERROR | No error happened.
wxPRINTER_CANCELLED | The user cancelled printing.
wxPRINTER_ERROR | There was an error during printing.

virtual wxPrintDialogData& wxPrinter::GetPrintDialogData | ( |  | ) | const
| virtual

Returns the print data associated with the printer object.

virtual bool wxPrinter::Print | ( | wxWindow * | parent,
|  | wxPrintout * | printout,
|  | bool | prompt = `true`
| ) |  |
| virtual

Starts the printing process.

Provide a parent window, a user-defined wxPrintout object which controls the printing of a document, and whether the print dialog should be invoked first.

Print() could return false if there was a problem initializing the printer device context (current printer not set, for example) or the user cancelled printing. Call GetLastError() to get detailed information about the kind of the error.

virtual wxDC* wxPrinter::PrintDialog | ( | wxWindow * | parent | ) |
| virtual

Invokes the print dialog.

If successful (the user did not press Cancel and no error occurred), a suitable device context will be returned; otherwise NULL is returned; call GetLastError() to get detailed information about the kind of the error.

Remarks
  The application must delete this device context to avoid a memory leak.

virtual void wxPrinter::ReportError | ( | wxWindow * | parent,
|  | wxPrintout * | printout,
|  | const wxString & | message
| ) |  |
| virtual

Default error-reporting function.

virtual bool wxPrinter::Setup | ( | wxWindow * | parent | ) |
| virtual

Invokes the print setup dialog.

Remarks
  The setup dialog is obsolete from Windows 95, though retained for backward compatibility.
