What is the difference between B21 and B1 Niimbot? 

Hi dear, the B1 printed width of the printer is 25-50mm, the B21 printer is 20-50mm.

Seems B21 also print 25-50mm. It's the B3S which points from 20mm up to 75mm. But the is a big difference between B1 and B21 for print speed. Check YT videos about print speed. B1 is WAY FASTER than B21. Not sure if B21S is faster than B21 though... and B21 has a metal body while B1 is plastic. I've read that B3S can use non branded stickers. Seems, but not sure... B21, can as well, but B1 cannot, because you need to scan the sticker roll with your phone in order to set it up, while B3S sticker rolls need to be set up manually in the settings.

The width of the label paper printed by D110 is 12-15mm,the maximum size label for D110 is 15*50mm The width of label paper printed by B21， B1 is 20-50mm, the maximum size label for B21,B1 is 50*80mm

​@@NIIMBOT Can you please clarify the maximum size difference between B 21 20x50 & B1 is 50x80? I want to know the difference between B1 & B21 other than the physical appearance of the two. Thank you 😊

The printed width of printer B21 is 20-50mm, the printed width of printer B1 is 25-50mm.

Hi, dear, B1 can recognize the template automatically and then you edit the content you want.

@@NIIMBOT Are there ready-made templates on any site?
