Have you looked to see if you can feed paper through the back of the printer, to use larger diameter thermal paper rolls? I was considering this one but there has been no info to see if this printer has an opening that would allow for external feeding of paper into the machine like the m03 has.
This one is the newest and I love it my sister has the old one and told me it's smaller is size with this one you can print 4 different sizes of paper you are going to love it ❣️ Amazon Storefront ⬇️ www.amazon.com/shop/diywithsusyz
