Your Airprint.NET helped me a lot writing my own server App and i understand that this a client App that send a job to a printer. Because i'm writing a server app i need to reply to the client that send request. Among the responses that i need to send is the Copies-Supported Attribute which is defined as RangeOfInteger (https://tools.ietf.org/html/rfc2911).
here's an example of how i set other attributes:
this.Group[AttrGroups.PrinterTag].Add(new Attribute(Tag.Keyword, "sides-supported", "one-sided"));
The above example set the sides-supported.
I can also use the same structure to set other value such as copie-default with Tag value = Integer
But i would also like to set copies-supported attributes, How do i set such value which has value attribute = RangeOfInteger.
