  • I am unable to find any information on printing QR codes. From the documentation provided I have been able to print 2D bar codes and text - I haven't yet tried a bitmap. Is there a native command set for QR code generation or is the expectation that I create my own QR as a bitmap and use the image commands?

  • The patient wasn't sure it would fit, but the dentist insisted that the tooth-cleaning drone prototype was a 'Minimum Viable Product'.

No public wish lists :(
