I quite like this Brother model I bought recently. The software was easy to install & feature rich. The tape consumables are reasonably priced & many types are available for different applications.
My own view is by eliminating the keyboard you lose some degree of portability I suppose. But OTOH the unit is only about label making, not data entry. Analogous to a printer. The software is more powerful than a teeny keyboard & allows updates as features & fonts & tape types become released. Its not a big deal to drive it off a laptop in the shop but for the most part I just print what I need in the house & take the labels out.
lol, I was going to post to avoid that one! Agree the idea of a label printer and cell phone is a big improvement, and the cartridge system works well, but I found the software horrible. Thought I was back in the 90's. Maybe it's best one out there, but the software really underwhelmed, no way to set margins (so you keying spaces or the labels are bunched together, you can only enter a few labels before the field is full and you have print them (with a long lead in that wastes lots of tape, auto cut simply does not work so I'm with scissors..... and so on. It could have been great.
