102
103
104The QPrinter class is a paint device that paints on a printer.
105<p>
106
107
108<p> On Windows it uses the built-in printer drivers. On X11 it
109generates postscript and sends that to lpr, lp, or another print
110command.
111<p> QPrinter is used in much the same way as <a href="qwidget.html">QWidget</a> and <a href="qpixmap.html">QPixmap</a> are
112used. The big difference is that you must keep track of the pages.
113<p> QPrinter supports a number of settable parameters, most of which
114can be changed by the end user when the application calls
115<a href="#setup">QPrinter::setup</a>().
116<p> The most important parameters are:
117<ul>
118<li> <a href="#setOrientation">setOrientation</a>() tells QPrinter which page orientation to use (virtual).
119<li> <a href="#setPageSize">setPageSize</a>() tells QPrinter what page size to expect from the
120printer.
121<li> <a href="#setResolution">setResolution</a>() tells QPrinter what resolution you wish the
122printer to provide (in dpi).
123<li> <a href="#setFullPage">setFullPage</a>() tells QPrinter whether you want to deal with the
124full page or just with the part the printer can draw on. The
125default is FALSE, so that by default you should be able to paint
126on (0,0). If TRUE the origin of the coordinate system will be in
127the top left corner of the paper and most probably the printer
128will not be able to paint something there due to it's physical
129margins.
130<li> <a href="#setNumCopies">setNumCopies</a>() tells QPrinter how many copies of the document
131it should print.
132<li> <a href="#setMinMax">setMinMax</a>() tells QPrinter and QPrintDialog what the allowed
133range for <a href="#fromPage">fromPage</a>() and <a href="#toPage">toPage</a>() are.
134</ul>
135<p> Except where noted, you can only call the set functions before
136<a href="#setup">setup</a>(), or between <a href="qpainter.html#end">QPainter::end</a>() and setup(). (Some may take
137effect between setup() and begin(), or between begin() and end(),
138but that's strictly undocumented and such behaviour may differ
139depending on platform.)
140<p> There are also some settings that the user sets (through the
141printer dialog) and that applications are expected to obey:
142<p> <ul>
143<p> <li> <a href="#pageOrder">pageOrder</a>() tells the application program whether to print
144first-page-first or last-page-first.
145<p> <li> <a href="#colorMode">colorMode</a>() tells the application program whether to print in
146color or grayscale. (If you print in color and the printer does
147not support color, Qt will try to approximate. The document may
148take longer to print, but the quality should not be made visibly
149poorer.)
150<p> <li> fromPage() and toPage() indicate what pages the application
151program should print.
152<p> <li> <a href="#paperSource">paperSource</a>() tells the application progam which paper source
153to print from.
154<p> </ul>
155<p> You can of course call these functions to establish defaults
156before you ask the user through <a href="#setup">QPrinter::setup</a>().
157<p> Once you start printing, calling <a href="#newPage">newPage</a>() is essential. You will
158probably also need to look at the <a href="qpaintdevicemetrics.html">QPaintDeviceMetrics</a> for the
159printer (see the <a href="simple-application.html#printersimple">print
160 function</a> in the Application walk-through). In previous versions,
161paint device metrics were valid only after the QPrinter has been set
162up, i.e. after <a href="#setup">setup</a>() has returned successfully. This is no longer
163the case and paint device metrics can be requested safely before set up.
164<p> If you want to abort the print job, <a href="#abort">abort</a>() will try its best to
165stop printing. It may cancel the entire job or just some of it.
166<p>
167<p> If your current locale converts "," to ".", you will need to set
168a locale (via the standard C setlocale() function) that doen't do this
169before using QPrinter. The "C" locale works well for this.

192<hr><h2>Member Type Documentation</h2>
193<h3 class=fn><a name="ColorMode-enum"></a>QPrinter::ColorMode</h3>
194
195<p> This enum type is used to indicate whether QPrinter should print
196in color or not.
197<ul>
198<li><tt>QPrinter::Color</tt> - print in color if available, otherwise in grayscale.
199<li><tt>QPrinter::GrayScale</tt> - print in grayscale, even on color printers.
200Might be a little faster than <a href="#ColorMode-enum">Color</a>. This is the default.
201</ul>
202<h3 class=fn><a name="Orientation-enum"></a>QPrinter::Orientation</h3>
203
204<p> This enum type (not to be confused with Qt::Orientation) is used
205to specify each page's orientation.
206<ul>
207<li><tt>QPrinter::Portrait</tt> - the page's height is greater than its width (the
208default).
209<li><tt>QPrinter::Landscape</tt> - the page's width is greater than its height.
210</ul><p> This type interacts with <a href="#PageSize-enum">QPrinter::PageSize</a> and
211<a href="#setFullPage">QPrinter::setFullPage</a>() to determine the final size of the page
212available to the application.
213
214<h3 class=fn><a name="PageOrder-enum"></a>QPrinter::PageOrder</h3>
215
216<p> This enum type is used by QPrinter to tell the application program
217how to print.
218<ul>
219<li><tt>QPrinter::FirstPageFirst</tt> - the lowest-numbered page should be printed
220first.
221<li><tt>QPrinter::LastPageFirst</tt> - the highest-numbered page should be printed
222first.
223</ul>
224<h3 class=fn><a name="PageSize-enum"></a>QPrinter::PageSize</h3>
225
226<p> This enum type specifies what paper size QPrinter should use.
227QPrinter does not check that the paper size is available; it just
228uses this information, together with QPrinter::Orientation and
229<a href="#setFullPage">QPrinter::setFullPage</a>(), to determine the printable area (see
230<a href="qpaintdevicemetrics.html">QPaintDeviceMetrics</a>).
231<p> The defined sizes (with <a href="#setFullPage">setFullPage</a>(TRUE)) are:
232<ul>
233<li><tt>QPrinter::A0</tt> - 841 x 1189 mm This value is not supported on windows.
234<li><tt>QPrinter::A1</tt> - 594 x 841 mm This value is not supported on windows.
235<li><tt>QPrinter::A2</tt> - 420 x 594 mm
236<li><tt>QPrinter::A3</tt> - 297 x 420 mm
237<li><tt>QPrinter::A4</tt> - 210 x 297 mm, 8.26 x 11.7 inches
238<li><tt>QPrinter::A5</tt> - 148 x 210 mm
239<li><tt>QPrinter::A6</tt> - 105 x 148 mm
240<li><tt>QPrinter::A7</tt> - 74 x 105 mm
241<li><tt>QPrinter::A8</tt> - 52 x 74 mm
242<li><tt>QPrinter::A9</tt> - 37 x 52 mm
243<li><tt>QPrinter::B0</tt> - 1030 x 1456 mm
244<li><tt>QPrinter::B1</tt> - 728 x 1030 mm
245<li><tt>QPrinter::B10</tt> - 32 x 45 mm
246<li><tt>QPrinter::B2</tt> - 515 x 728 mm
247<li><tt>QPrinter::B3</tt> - 364 x 515 mm
248<li><tt>QPrinter::B4</tt> - 257 x 364 mm
249<li><tt>QPrinter::B5</tt> - 182 x 257 mm, 7.17 x 10.13 inches
250<li><tt>QPrinter::B6</tt> - 128 x 182 mm
251<li><tt>QPrinter::B7</tt> - 91 x 128 mm
252<li><tt>QPrinter::B8</tt> - 64 x 91 mm
253<li><tt>QPrinter::B9</tt> - 45 x 64 mm
254<li><tt>QPrinter::C5E</tt> - 163 x 229 mm
255<li><tt>QPrinter::Comm10E</tt> - 105 x 241 mm, US Common #10 Envelope
256<li><tt>QPrinter::DLE</tt> - 110 x 220 mm
257<li><tt>QPrinter::Executive</tt> - 7.5 x 10 inches, 191 x 254 mm
258<li><tt>QPrinter::Folio</tt> - 210 x 330 mm
259<li><tt>QPrinter::Ledger</tt> - 432 x 279 mm
260<li><tt>QPrinter::Legal</tt> - 8.5 x 14 inches, 216 x 356 mm
261<li><tt>QPrinter::Letter</tt> - 8.5 x 11 inches, 216 x 279 mm
262<li><tt>QPrinter::Tabloid</tt> - 279 x 432 mm
263<li><tt>QPrinter::Custom</tt>
264<li><tt>QPrinter::NPageSize</tt> - (internal)
265</ul><p> With <a href="#setFullPage">setFullPage</a>(FALSE) (the default), the metrics will be a bit
266smaller; how much depends on the printer in use.
267
268<h3 class=fn><a name="PaperSource-enum"></a>QPrinter::PaperSource</h3>
269
270<p> This enum type specifies what paper source QPrinter is to use.
271QPrinter does not check that the paper source is available; it
272just uses this information to try and set the paper source.
273Whether it will set the paper source depends on whether the
274printer has that particular source.
275<p> Note: this is currently only implemented for Windows.
276<ul>
277<li><tt>QPrinter::OnlyOne</tt>
278<li><tt>QPrinter::Lower</tt>
279<li><tt>QPrinter::Middle</tt>
280<li><tt>QPrinter::Manual</tt>
281<li><tt>QPrinter::Envelope</tt>

289<li><tt>QPrinter::FormSource</tt>
290</ul>
291<h3 class=fn><a name="PrintRange-enum"></a>QPrinter::PrintRange</h3>
292
293<p> This enum is used to specify which print range the application
294should use to print.
295<ul>
296<li><tt>QPrinter::AllPages</tt> - All pages should be printed
297<li><tt>QPrinter::Selection</tt> - Only the selection should be printed.
298<li><tt>QPrinter::PageRange</tt> - From page, to page option.
299</ul><p> <p>See also <a href="#setPrintRange">setPrintRange</a>() and <a href="#printRange">printRange</a>().
300
301<h3 class=fn><a name="PrinterMode-enum"></a>QPrinter::PrinterMode</h3>
302
303<p> This enum describes the mode the printer should work in. It
304basically presets a certain resolution and working mode.
305<ul>
306<li><tt>QPrinter::ScreenResolution</tt> - Sets the resolution of the print device to
307the screen resolution. This has the big advantage that the results
308obtained when painting on the printer will match more or less
309exactly the visible output on the screen. It is the easiest to
310use, as font metrics on the screen and on the printer are the
311same. This is the default value. ScreenResolution will produce a
312lower quality output than HighResolution and should only be used
313for drafts.
314<li><tt>QPrinter::PrinterResolution</tt> - Use the physical resolution of the
315printer on Windows. On Unix, set the postscript resolution to 72
316dpi.
317<li><tt>QPrinter::HighResolution</tt> - Use printer resolution on windows, set the
318resolution of the postscript driver to 600dpi.
319<li><tt>QPrinter::Compatible</tt> - Almost the same as PrinterResolution, but keeps
320some peculiarities of the Qt 2.x printer driver. This is useful
321for applications ported from Qt 2.x to Qt 3.x.
322</ul>
323<h3 class=fn><a name="PrinterOption-enum"></a>QPrinter::PrinterOption</h3>
324
325<p> This enum describes various printer options that appear in the
326printer setup dialog. It is used to enable and disable these
327options in the setup dialog.
328<ul>
329<li><tt>QPrinter::PrintToFile</tt> - Describes if print to file should be enabled.
330<li><tt>QPrinter::PrintSelection</tt> - Describes if printing selections should be enabled.
331<li><tt>QPrinter::PrintPageRange</tt> - Describes if printing page ranges (from, to) should
332be enabled

571top-left corner of the paper if <em>fp</em> is TRUE, or where it thinks
572the top-left corner of the printable area is if <em>fp</em> is FALSE.
573<p> The default is FALSE. You can (probably) print on (0,0), and
