+</ul> +<hr><a name="details"></a><h2>Detailed Description</h2> + + +The QPrinter class is a paint device that paints on a printer. +<p> + + +<p> On Windows it uses the built-in printer drivers. On X11 it +generates postscript and sends that to lpr, lp, or another print +command. +<p> QPrinter is used in much the same way as <a href="qwidget.html">QWidget</a> and <a href="qpixmap.html">QPixmap</a> are +used. The big difference is that you must keep track of the pages. +<p> QPrinter supports a number of settable parameters, most of which +can be changed by the end user when the application calls +<a href="#setup">QPrinter::setup</a>(). +<p> The most important parameters are: +<ul> +<li> <a href="#setOrientation">setOrientation</a>() tells QPrinter which page orientation to use (virtual). +<li> <a href="#setPageSize">setPageSize</a>() tells QPrinter what page size to expect from the +printer. +<li> <a href="#setResolution">setResolution</a>() tells QPrinter what resolution you wish the +printer to provide (in dpi). +<li> <a href="#setFullPage">setFullPage</a>() tells QPrinter whether you want to deal with the +full page or just with the part the printer can draw on. The +default is FALSE, so that by default you should be able to paint +on (0,0). If TRUE the origin of the coordinate system will be in +the top left corner of the paper and most probably the printer +will not be able to paint something there due to it's physical +margins. +<li> <a href="#setNumCopies">setNumCopies</a>() tells QPrinter how many copies of the document +it should print. +<li> <a href="#setMinMax">setMinMax</a>() tells QPrinter and QPrintDialog what the allowed +range for <a href="#fromPage">fromPage</a>() and <a href="#toPage">toPage</a>() are. +</ul> +<p> Except where noted, you can only call the set functions before +<a href="#setup">setup</a>(), or between <a href="qpainter.html#end">QPainter::end</a>() and setup(). (Some may take +effect between setup() and begin(), or between begin() and end(), +but that's strictly undocumented and such behaviour may differ +depending on platform.) +<p> There are also some settings that the user sets (through the +printer dialog) and that applications are expected to obey: +<p> <ul> +<p> <li> <a href="#pageOrder">pageOrder</a>() tells the application program whether to print +first-page-first or last-page-first. +<p> <li> <a href="#colorMode">colorMode</a>() tells the application program whether to print in +color or grayscale. (If you print in color and the printer does +not support color, Qt will try to approximate. The document may +take longer to print, but the quality should not be made visibly +poorer.) +<p> <li> fromPage() and toPage() indicate what pages the application +program should print. +<p> <li> <a href="#paperSource">paperSource</a>() tells the application progam which paper source +to print from. +<p> </ul> +<p> You can of course call these functions to establish defaults +before you ask the user through <a href="#setup">QPrinter::setup</a>(). +<p> Once you start printing, calling <a href="#newPage">newPage</a>() is essential. You will +probably also need to look at the <a href="qpaintdevicemetrics.html">QPaintDeviceMetrics</a> for the +printer (see the <a href="simple-application.html#printersimple">print + function</a> in the Application walk-through). In previous versions, +paint device metrics were valid only after the QPrinter has been set +up, i.e. after <a href="#setup">setup</a>() has returned successfully. This is no longer +the case and paint device metrics can be requested safely before set up. +<p> If you want to abort the print job, <a href="#abort">abort</a>() will try its best to +stop printing. It may cancel the entire job or just some of it. +<p> +<p> If your current locale converts "," to ".", you will need to set +a locale (via the standard C setlocale() function) that doen't do this +before using QPrinter. The "C" locale works well for this. +<p> The TrueType font embedding for Qt's postscript driver uses code +by David Chappell of Trinity College Computing Center. +<p> +<p> Copyright 1995, Trinity College Computing Center. +Written by David Chappell. +<p> Permission to use, copy, modify, and distribute this software and +its documentation for any purpose and without fee is hereby +granted, provided that the above copyright notice appear in all +copies and that both that copyright notice and this permission +notice appear in supporting documentation.
