Printing an svg from withing PyQt5

DieterV

Hi,

I'm working on a system that scans barcodes on invitations at events and prints out the badges for the attendees.
For my first version, I generated pdf's and printed those (the badge printer shows up as a regular printer). That worked under Linux, but under Windows, libcairo wasn't avaiable. I worked my way around using poppler that but it wasn't pretty.

Now I'd need more flexibility in generating content (I'd need boxes with/without ticks and such) and I'd like to avoid pdf altogether.

SVG seemed like a good format, using svgwrite. However, I can't seem to figure out how to send those to the printer.

printer = QPrinter(QPrinter.HighResolution)
        printer.setOrientation(QPrinter.Landscape)
        printer.setPageSizeMM(QSizeF(54.19, 85.2))

Sets up the printer correctly (it worked for the pdf).
Then I would do:

painter = QPainter()
painter.begin(printer)

To start "writing" to the printer and end with

painter.end()

In between that, I'm lost and I can't seem to find how to do it (so 2 svg files for front/back and being deployable on Linux and Windows).

Does anyone have any pointers?

In case anyone comes looking with the same question, I managed to get it working using two pre-created svg files (test1.svg and test2.svg):

        printer = QPrinter(QPrinter.HighResolution)
        printer.setOrientation(QPrinter.Landscape)
        printer.setPageSizeMM(QSizeF(54.19, 85.2))

        painter = QPainter()
        painter.begin(printer)
        rend = QSvgRenderer('test1.svg')
        rend.render(painter)
        printer.newPage()
        rend = QSvgRenderer('test2.svg')
        rend.render(painter)

        painter.end()

Keep in mind that this does not show the print dialog box but directly prints to the default printer with the default settings.
