// Now, inside any Qt function (may be a slot):

QPrintDialog *dialog = new QPrintDialog( &printer, this );
dialog->setWindowTitle( tr( "Zebra label" ) );
if ( dialog->exec( ) != QDialog::Accepted )
return;
// This is the sample label. Can be anything.
const char label[] =
"^XA~TA000~JSN^LT0^MNW^MTD^PON^PMN^LH0,0^JMA^PR4,4^MD0^JUS^LRN^CI0^XZ\n"
"^XA\n"

"^LS0\n"
"^BY2,3,54^FT24,109^BCN,,Y,N\n"
"^FD>;43210000>773>0000^FS\n"
"^PQ1,0,1,Y^XZ\n";
// Informative only.
ui->txtLabelScript->setPlainText( label );
// Call the printing function.
if ( print_label( label, printer.printerName( ).toAscii( ), "Zebra_Label" ) == 0 )
qDebug( ) << "CUPS Error: " << ippErrorString( cupsLastError( ) );
它已经完成了。 不要忘记链接libcups(-lcups)。 我仍然希望任何伙伴添加另一个解决方案，证明Qt-only是可能的。同时，这已经足够了。 谢谢大家。
