I wanted to try these out due to the zero waste liner and recycle friendly adhesive so my customers can just throw everything, packing slip and all straight into the recycle bin since I use paper envelopes for most orders. Overall there's some minor annoyances but since none of them affect the customer I'm really liking these labels.
I wish there were a fanfold option since my printer takes the 1" core rolls and those ones are annoying because they run out so often and the labels are too curved especially as it gets low. So I got a large roll and was able to unroll into an old fanfold box in about 15 minutes. Maybe next time I'll bribe one of the neighborhood children to do it.
I use a Zebra GK420d on a CUPS print server and after setting it to 'mark sensing' it was detecting the labels correctly but the top was getting cut off by a couple mm and it seemed to be ignoring the top offset setting. I flipped the stack over so it was feeding reverse from how the labels normally come off the roll and now the cutoff is minimal. Probably just a driver issue or something, but if I were using the roll it would be a problem.
I ordered at the end of July 2020 and believe I got the new batch. The stickers are stuck to the liner with more enthusiasm than your average labels so they do make better packing slips. But if you pack orders with gloves on and normally tear off single labels before peeling them, that's going to be a problem. I'm now leaving the labels connected and using the pinch and roll method and it's not slowing me down much.
