| 298 | the printer's configuration. |

| 300 | \ingroup standard-dialogs |
| 301 | \ingroup printing |
| 302 | \inmodule QtPrintSupport |
| 303 | |
| 304 | The dialog allows users to change document-related settings, such |
| 305 | as the paper size and orientation, type of print (color or |
| 306 | grayscale), range of pages, and number of copies to print. |
| 307 | |
| 308 | Controls are also provided to enable users to choose from the |
| 309 | printers available, including any configured network printers. |
| 310 | |
| 311 | Typically, QPrintDialog objects are constructed with a QPrinter |
| 312 | object, and executed using the exec() function. |
| 313 | |
| 314 | \snippet code/src_gui_dialogs_qabstractprintdialog.cpp 0 |
| 315 | |
| 316 | If the dialog is accepted by the user, the QPrinter object is |
| 317 | correctly configured for printing. |

| 325 | The printer dialog (shown above in Plastique style) enables access to common |
| 326 | printing properties. On X11 platforms that use the CUPS printing system, the |
| 327 | settings for each available printer can be modified via the dialog's |
| 328 | \uicontrol{Properties} push button. |
| 329 | |
| 330 | On Windows and \macos, the native print dialog is used, which means that |
| 331 | some QWidget and QDialog properties set on the dialog won't be respected. |
| 332 | The native print dialog on \macos does not support setting printer options, |
| 333 | i.e. setOptions() and setOption() have no effect. |
| 334 | |
| 335 | In Qt 4.4, it was possible to use the static functions to show a sheet on |
| 336 | \macos. This is no longer supported in Qt 4.5. If you want this |
