Printing multiline tickets



  • Hi,

    I'm using a printer VKP80III to print tickets/recipes.
    And for now, the code look like this:

    QPrinterInfo _printer = ...;
    
    ...
    
    QPrinter printer(_printer);
    printer.setPaperSize(QSize(80, 120), QPrinter::Millimeter);
    printer.setPageMargins(15, 15, 15, 15, QPrinter::Millimeter);
    printer.setFullPage(true);
    
    QString tmp = message;
    tmp.replace("\n", "\r\n");
    
    QPainter painter;
    painter.begin(&printer);
    painter.setFont(QFont("Tahoma", 8));
    painter.drawText(QPoint(0, 0), tmp);
    painter.end();
    

    My paper is 80x120 mm.
    I expect an output like:

    --------------------------------
    ANY BANK
    --------------------------------
    TERMINAL #	123456
    SEQUENCE #	12345
    AUTH #	25688KK
    DATE 	11/11/2014
    TIME	16:52:24
    	
    CARD NUMBER	**** **** **** 0069
    	
    CUSTOMER NAME	BERNARD MADOFF
    	
    DISPENSED AMOUNT	$200.00
    REQUESTED AMOUNT	$200.00
    FROM ACCOUNT	CHECKING
    TERMINAL FEE	$1.00
    	
    TOTAL AMOUNT	$201.00
    BALANCE	$22,234,396.82
    
    
    --------------------------------.
    

    But only get this:

    -------------------------------- ANY BANK -------------------
    

    The rest doesn't print since it never go to a new line.
    Does anyone have a solution for this?

    Thanks in advance.

    ps: The ticket content is just a test, I'm not working for a bank.



  • QPainter::drawText(const QPoint & position, const QString & text)
    does not support newlines, you need to use the
    void QPainter::drawText(const QRectF & rectangle, int flags, const QString & text)
    version of that function to get those to work.
