We are going to start shipping ups surepost and need to be able to use a 4" x 8" shipping label with our thermal printers. Apparently shipstation does not support this size of label which we find a bit perplexing. If ups surepost needs this size of label why is it not supported by shipstation - I am told that other platforms (ie Shipwire) support this size label as told by our ups rep.
Now we are in a situation since we've used shipstation for years but need to be able to print this size label???
Any ideas on how to make it happen?
