Printing to Brother QL-600B

Hi All,

Im hoping someone on here can help me. I am attempting to use the new Print() command within a digital sign in system app. This app will print a label with the users details using the Brother QL-600B label printer. The only problem is at the moment is that everytime I try to print I get an error that the selected paper dimensions from powerapps does not match the installed labels in the printer. And I know this is not the case because when I select paper size on the google options I am selecting the correct label.

It seems that everytime I attempt to print to the printer from a browser, it is locked to only 29mm x 90mm. Please see below the error from the printer.
