I'm trying to print QRCode-labels on a Brother QL580 label printer directly with PHP (Version 5.6).
The function i'm calling to print a QRCode returns:
return chr(27) . 'iQ32000020' . $this->dataString . chr(92) . chr(92) . chr(92);
This works only in part. The QRCode is printed correctly (the
$dataString is included) but the preceding 8 parameters seem to be ignored.
I want to increase the cell size of the QRCode (first parameter) but changing the value does not take effect.
The documentation says:
Any help would be apreciated!
