I have just purchased one of the Dymo Label printers the one that is advertised on TV, and I have to say I'm well impressed with it, easy to install and so easy to use and at this time of the year has come into its own.(usb connectivity)
I use just as a home user and not in an office although I have seen them in offices.
The software offer loads of different templates for all different size labels and you can create logos etc etc.
I think the only problem people might have with it, is the price, not cheap, I paid £99.88 from click here sorry people this is not a sales pitch, but if you fed up loading your printer and wasting Avery labels then this could be an answer.
