=head1 NAME

Prima::PrintDialog - standard printer setup dialog

=head1 DESCRIPTION

Provides a standard dialog that allows the user to select a printer
and its options. The toolkit does not provide the in-depth management
of the printer options; this can only be accessed by executing a printer-specific
setup window, called by C<Prima::Printer::setup_dialog>. The class invokes
this method when the user presses 'Properties' button. Otherwise, the class
provides only selection of a printer from the printer list.

When the dialog finished successfully, the selected printer is set as the current
by writing to C<Prima::Printer::printer> property. This technique allows direct use of
the user-selected printer and its properties without prior knowledge of the
selection process.

=head1 SYNOPSIS

	use Prima::PrintDialog;

	$dlg = Prima::PrintSetupDialog-> create;
	if ( $dlg-> execute) {
		my $p = $::application-> get_printer;
		if ( $p-> begin_doc ) {
			$p-> text_out( 'Hello world', 10, 10);
			$p-> end_doc;
		}
	}
	$dlg-> destroy;
