So niimbot label printers store a table of 20 of the last rolls it has seen, If you block the writing of the NFC tag it updates the internal table with the usage count anyway... It also sets the printing density to -3 if it can't see the NFC tag when a print job is sent.

Reversing a label printer.... cause fuck your DRM label rolls thats why... Anyway... I need to change the code to my suitcase. (Granted, they do encrypt data on the tag too... but still...)

Would be a shame if we binary patched the firmware to disable these things ;-) In other news: My D110M now prints on rolls of labels without a NFC tag. But as the label size is determined by the NFC tag, gonna need to binary patch in some auto sensing / custom commands to set the label size ;-)
