I ordered the ecolabels along with the TSC printer & (of course) now regret not ordering two lots of labels. They fitted into the printer really easily, everything just works and there's been no wastage trying to ensure everything is appropriately lined up & working. I was also very impressed because I rang HeapsGood with a query prior to purchase and the phone was answered by a person (not some interminable IVR) and that resulted in a quick & easy answer (so obviously I then purchased almost immediately).
