will this work on tyco printers? Model TE3112

The RL2956TT is a 1" x 0.5" Standard White Thermal Transfer label on a 1" core with a 4" outer diameter. We have not tested our roll products with Tyco's TE3112 printer, however this does appear to be a thermal transfer printer. You'll just want to verify the printer specifications to ensure the core size and outer diameter meet the requirements for the printer, and that the printer is set up for Gap Sensing at 0.125".

Does this work with MUNBYN Thermal Label Printer, 4"x6"?

Our RL2956TT is a 1" x 0.5" standard white thermal transfer label on a 1" core with a 4" outer diameter. We haven't tested Munbyn thermal printers to confirm compatibility so you'll want to review the specifications for your printer model.
