Our original TSP100 had a cutter, I ordered elsewhere and receive a TSP100 without the auto paper cutter. Back it went and now looked closer. This TSP100 has a II after the model no. Shows TSP100II (roman numerals). It is also TSP143. Works perfect with our POS, they helped with setup. This unit has a USB our original had Ethernet. Did take several hours to hey up and running but not the fault of Star Micronics, they too were helpful. Will buy again.

This is a fantastic product, worked as expected with tons of options and the ability to configure settings is very handy. Everything installed properly and it works despite not having a dedicated POS server! The ability to reduce receipt size has been a huge thing for us. Only issue we ran into was an issue on our side of things not fully uninstalling our old drivers, but once we did a full uninstall it worked like a dream. The ability of the printer to cut the receipt off for us has been a big help and makes them look much more professional over all and speeds things up considerably more than we expected.
We were hesitant about getting this printer since it did not have an Off switch but so far that hasn't been an issue since the printer itself hasn't had the same errors we've been experiencing with an old receipt printer we were using without much success before.

Pros-
Eco settings to shorten receipts
Speedy printing!
Tons of customization settings for specific needs that come with its own program, this has been a huge difference compared to our last which required you to dig around to even have a hope to adjust things
Effective with our POS program despite it not being listed as compatible
Works when printing a receipt from a browser!
A list of compatible POS programs one could pick from
We don't use it but the ability to print receipts from a mobile phone is a big plus that it's at least an option

Cons-
Size, this isn't a small machine like some others we've seen or had
Uses thermal paper (this is more or less a downside just because of how much non-thermal paper we have from our last printer)

Nothing special, regular receipt printer. When unplugged for a few days (moving units) it can take some time for it to reboot & come on line. had to leave it plugged in over night to regain power. Don't freak when it happens to you, it is part of the energy star program.

It is bulky and heavy but works with the square system, if you are willing to take the risk they are much cheaper used.

Easy to connect! I purchased this to use with my Android Square POS. I was up and running with this and my cash drawer within minutes!
I do, however, wish the printer came with a full roll of receipt paper!
