  #
  # This print_to_sprint call fails silently if there is an error. Instead
  # of returning success, the result of the send_print_request call should
  # be used to check the response status and response body. Examples:
  #
  # The following response body is returned in a 200 response.
  # {"errors":[{"message":"Variable 'printRequest' has an invalid value: Expected
  #   type 'Int' but was
  #   'Double'.","locations":[{"line":1,"column":16}],"extensions":{"classification":"
  #   ValidationError"}}]}
  #
  # The following response body is returned in a 500 response.
  # {"timestamp": "2023-08-02T14:46:30.160+00:00","status": 500,"error": "Internal
  #   Server Error","path": "/graphql"}
  #
  # When sprint cannot log in to printer, the details are available in response body.
  #
  # A successful response has a job id in response body.
  #
  # Use errors.add to show proper feedback in the view.
