Getting CUPS set up with a Brother QL-820NWB label maker

Help
1

I am trying to get a Brother QL-820NWB label maker to work with Nixos. I was able to get the printer installed with the following settings in my configuration.nix

  services.printing = {
    enable = true;
    logLevel = "debug";
    drivers = [
      pkgs.brlaser
      pkgs.brgenml1lpr
      pkgs.brgenml1cupswrapper
      pkgs.ptouch-driver
    ];
  };

I then imperatively installed it through the CUPS web portal. I can see the printer, and I can send jobs too it, however, any job I send results in an error on the printer screen “Check the print data and try again”. And " “Invalid values for page margins: Bottom: 8; Top: 8” in the job log.

To resolve the page margin issue, I tried adjusting the sizes in the ppd file that came with the driver, however, no matter what value I put in for HWMargin or DefaultImageableArea, it results in that value being invalid.
