[2 Rolls, 440 Labels] 4”x 6” Postage Thermal Shipping Labels Compatible with Dymo 4XL 1744907 LabelWriter

This review goes out to everyone complaining these don’t work with the Dymo4xl… I hope you see this because it’ll change your life! I’ve had my 4xl for years, I used brand name at first and they were fine, but too expensive. I soon switched to off brand which had their problems– typically a few labels would print and then the machine spit out dozens of blanks before locking up.. SO FRUSTRATING!! I ship in bulk so these hiccups were a nightmare until I learned a ‘trick’ from another Amazon review. Surprise surprise– Dymo puts a little security tag in each official roll which the machine recognizes as proprietary and prints as normal. So the solution is simple: purchase an official Dymo roll, print all your labels and before you toss the cardboard cylinder look for the security tag, peel it off (I used a razor to score a square around it and peel off a bit of board with it as to not destroy it), affix it with tape to the interior of the printer on the bottom half (for me it was left center on the instruction sticker that show an upside down label crossed out), now install your new roll and print as normal! Works like a dream for me, and I’m so happy with the savings.I took off a star because the last roll was maybe 50 labels short… But for the overall quality and price I can’t complain too much.I hope this helps!
