DYMO 450 vs 550: Label Compatibility Differences
Compare DYMO LabelWriter 450 and 550 label compatibility before buying third-party rolls.
The important difference is label identification technology.
The 450 family is part of the classic compatible-label ecosystem. The 550 generation uses smart-label identification, so ordinary third-party rolls that fit a 450 should not be assumed to work in a 550.
