It is advertised with "Guaranteed not to jam," so I can not confirm, unfortunately. My printer (HP 8600) draws in normal as well as the high speed print mode often 2-4 label sheets, and printed all - result: 4 * 8 = 32 lost labels. If you are not careful, you quickly printed up without a viable to have the whole package, so you should definitely standing by, and cancel printing if necessary. I am now so far, always to be only one sheet into the printer and to migrate to the PC, click once on the "Print" and back again - this is annoying because the printer is relatively new and widespread and no other problems with paper or catchment has.
Otherwise, the labels keep their promise, they keep well on surfaces, the color quality of the paper to be printed is not bad, and it is marked, the direction in which they must be placed in the printer. Unfortunately, however, the price in recent years has grown rapidly and the retail sale has been reduced to just 3 variants. The delivery time on the internet amounted to me one month (although this was previously determined) - for short term affairs therefore not recommended.
Keep one printing always order a larger package - this is cheaper and you will be one way or another "beat" (even if the machine pull slightly crooked).
