You should be able to get this directly from the dealer that sold you the GT-3 printer or from Brother directly.

thanks for the info Mark, i will make sure i get it upgraded when i make the 361 jump for the agitate white feature.Steve,
The only things that I am aware of is Brother the networking feature (hardware already existed) and they added a Agitate White feature - which would not apply to your GT-341 setup. There are probably other little things they did, but nothing that jumps out at me. There could be an issue if you are using an old firmware with the latest driver (i.e. which might or might not have the 16" x 18" platen size depending on which one you have installed).
