Have not purchased this printer, but wanted to let people know that this is not the only printer that will work with Square. I have two Star Micronics printers, one Ethernet and one Bluetooth and both work fine with the Square app for iPad. I also have Ethernet based cash drawers that connect through the printers and those works just as well. This probably has the easiest set up, but it is not the only way.
But my point is that an adding machine paper-receipt looks unprofessional in some businesses.  An inexpensive ink jet or better, a multitasking network office printer that is already in use would make a LOT more sense for me.  I’m sure they are robust and work fine, they just don’t suit my business and I don’t like being so limited in the TYPE of printer I can use.
If my answer solved your problem, would you mind marking it as “Best Answer”? That’ll help the rest of the community find what they’re looking for. If not, just write back, and I’ll continue to help. Thanks!
The Ethernet printers compatible with Square Point of Sale are thermal printers. They require heat-sensitive paper and won’t work with non-thermal receipt paper. These types of printers aren’t ideal for kitchens or high-temperature working areas.

I’d like to take a step back from discussing integration challenges to mention a few examples from the Square Register code base that made my life easier for this project. The code separates operations looking for connected peripherals and interacting with them and uses abstract superclasses to provide a consistent API to the rest of the app. Because the code was so robust, my new printer code fit well into the rest of the app, and existing code used by other printers fit well into my own new code. One good example is our receipt image renderer. The renderer works by putting data into an HTML document styled by CSS, rendering that HTML into an unseen web view and then rendering the view into PNG image data that can be sent to the printer. The HTML and CSS scale to fit different-sized windows and thus are a good generalizable solution for multiple print widths. All of the printers that we had previously supported (WiFi and USB printers) printed three-inch wide receipts. However most of the Bluetooth printers I worked with use two-inch wide paper. Thanks to the flexibility of our renderer, all I had to do was set the correct print width of a printer and voilà — the receipts were seamlessly resized and looked great.
Impact printers only print order tickets for a kitchen. They’re not affected by heat and can withstand warm environments. They require heat-sensitive paper and won’t work with non-thermal, receipt printer paper. 
A printer-driven cash drawer must be connected to an receipt printer to open automatically. Otherwise you’ll need to manually open the drawer using the cash drawer key. A USB cash drawer (requires Square Stand) will open automatically when connected.
Generally speaking, the Star printers will just show TSP100 on the front of the actual printer but those are the model numbers; it is kind of confusing. Feel free to share a link or two to the printers you’re viewing, I’d be happy to confirm. 
If the email address entered for receipt delivery is no longer active or is incorrect, Square will need to unlink this information from your customer’s payment card. Have your customer contact us for help.

Unless proven otherwise, I agree.  And in my business, giving a client a receipt on what amounts to a piece of adding machine paper is unprofessional.  I should be able to use any printer that is compatible with the iPad, not just the uni-tasker receipt printers.
