Label printers are pretty common in the trash these days. It’s either they are just out of film or the batteries are dead.
this one actually had a broken battery terminal, the battery unable to make contact with the lead end because it
was pushed back inside the machine. A little JB weld will hold things together, probably stronger than the orignal design. Time to print some labels, this thing even had new batteries. about an 11 minute fix because i had to find the glue.
