Hi there,
I also have got a Smart Label Printer 100, they are really good printers. I sometimes have a few problems with the quality of my labels though if not printing basic labels. For example, for a while now i have been homebrewing traditional ale in my spare time and i have been designing and printing my own labels to put on the bottle but the quality of my labels when being printed by my label printer are quite poor. I am thinking of may be paying for them to be printing professionally instead as i want them to look great.
