A bit should keep an eye on costs but you - print stamps rather not pay. There's brands buy much cheaper than buying expensive rolls of labels and print. But mailing labels for example. Can be quickly with this unit, clean and convenient labeling. Likewise, everything else does not have to keep "forever", because it is, after all, to thermal printing, which fades with time. How long does the printing and remain legible, I can not say, however, even after two months of use. None of the first early August 2013 as a test printed labels is yet even begin to fade (Addendum March 2014: Pressure is still perfectly legible, not a bit faded).
Conclusion: If you have to print a lot of labels that not very long must remain legible, but can not fill an entire sheet each time makes no mistake when he reaches 450 Turbo for Dymo LabelWriter.
