It's pretty frustrating. I can set it manually each time I print something from that device (Dymo 4XL label printer) but thats not what I want to do. I want to set it as the default size under printer settings so that I can have it be selected by default when I go to print with the Dymo 4XL. I can see that there is a method to do it via CUPS (I have it on a print server) which would be great, but 4"x6" isnt available there either lol. THANK YOU!
