Alignment Insert - NIIMBOT B21S

The borders I put on the stickers always come out unaligned. I tried to play around with the printer Offset settings and it did not help. Because there is a big free space so the paper roll moves left and right (A significant big gap for 1mm-margins accuracy). Boost MeWhat is MORE FUN for me than printing, is designing CAD.If I had the encouragement, I would print a lot of NEEDED stuff like this and other on my profiles.I like to publish Unique ideas that no one else has published before.My work is not derivatives.BOOST ME. THANK YOU.
