The printer that Square supports is one of the largest used brands in the receipt printer market.  They are not getting kickbacks on printers as the printers are sold by hundreds of places including Amazon, and the buyer doesn’t know you are buying it to print with Square as the printer is also used by 100s of other POS systems. More printer options would always be better, but as this is one of the industry standard printers it only makes sense they support it.
The STAR MICRONICS TSP654IIBI is fast and easy to configure. It is Apple MFi certified. It has auto connect and so it will connect to your iPad automatically. If you want to setup your receipt printer fast, this may be one of the best options. There is no serial cable, ethernet cable or USB connection. That seems like a positive benefit. If you move around a lot or you don’t want to mess with cables the STAR MICRONICS TSP654IIBI may be want you want.
Square is not interested in using anyone but Star. And their attitude is that they frankly don’t care. I know, I have emails from them about it. If I was to guess, I would bet they have a deal with Star that funds their (insert pizza parties, to silk pockets). But lets be realistic. I mean it has to be something viable, right? The fact that Star uses the same print protocals that Epson uses has no bearing on an Epson receipt printer not working. It goes in the same line as Android devices can’t use bluetooth devices… although that new chip reader is bluetooth. It is a lack of customer service and they need to step up to the plate, or someone is going to come along and take their business away from them.
I have a friend who runs a small shop and knew the Esky ES-CD01 Heavy Duty RJ-12 Key-Lock Cash Drawer would be perfect for his application. This drawer was a massive upgrade to the system he had been using. He had tried other drawers with different connections and designs, however this one was really the best.
Most receipt printers I have seen use a wired ethernet connection, so you could add a slick Lantronix xPrintServer which uses AirPrint to avoid needing a computer running for your iOS devices to print to these specialized printers.
Please note, these printers can only be used with iOS devices at this time. I don’t have a timeline for when they’ll be supported with Android devices yet. But I’ll report back when I have an update! 😀

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.
When you connect to the USB Receipt Printer or Ethernet Receipt Printer with the included cable, the cash drawer will open every time you complete a cash sale. Or use the included keys to manually open.
Be sure the printer and the iPad are connected to the same network. To confirm this or change your Wi-Fi network, go to the iPad’s Settings and tap “Wi-Fi” located in the left sidebar. Then select the network that the router is broadcasting and click “Connect”.
Square systems are primarily compatible with Ethernet or Bluetooth interface printers (depending on the tablet you are using, Android tablets with USB ports and USB On-The-Go or USB Host mode can use USB interface printers). The compatible printers for Square systems are as follows:
I spent years in jobs that included lots of cash handling. This cash drawer is the nicest I’ve seen. It’s solid build will last for years and its finish is just lovely. It triggers cleanly and the drawer all but shoots out when triggered. I’m very pleased.
Make sure not to send your customers’ receipts to yourself. You’ll receive a payment confirmation after every successful transaction, and you can view payment details from your online Square Dashboard.

I haven’t yet seen a receipt printer that is airprint compatible though, allowing more apps to use it. While credit card acceptance and sales apps would obviously benefit, I can imagine a number of other uses for a small printer that prints bits of disposable information. The daily forecast, sudoku puzzles, today’s schedule, todo lists, etc, for those who have to share their iPad with a spouse or children, for instance.

Last but not least, though I’m enough of a geek that the code itself would have been interesting and fun for me, it was really special getting to see first-hand how the product truly helped people. Meeting a merchant who had previously only been able to give out handwritten receipts, handing her a Bluetooth printer, and seeing how our new feature would make her job easier was the highlight of my summer.

We really like the Apple MFi certification with the auto connect feature. We also like the small footprint of this receipt printer. Overall this is one easy and fast printer to setup. The Apple MFi makes it real easy. You just turn the printer on within range of your iPad.

As VanKalkerFarms answer states, Point of Sale is not compatible with standard desktop printers at this time. A possible solution might be to view your receipts on your online Dashboard after the transaction is complete and you can print them from there on a desktop printer. 
This video, from http://www.beaglehardware.com, describes how to connect the approved printer and cash drawer to Square Register. With Square Register, you can print receipts for your customers at the counter. Connect to a cash drawer to make change for customers and store cash. The cash drawer will automatically open when connected to a supported receipt printer for every cash transaction and refund on your iPad or Android device.
This printer is fast. Thermal printers print very fast, and the internals are actually much simpler than the ones at my work. You simply open it up, drop the paper inside (yes, it’s a drop in, which makes it much easier to replace the roll once it has run out) and then feed the paper over the top.
I started off the implementation of Bluetooth printer support by using the same concurrency model used by our WiFi printer code and running Bluetooth printing and printer discovery blocks on a global concurrent queue. I quickly found what appeared to be a non-deterministic bug — sometimes I could print a receipt with no problem, and other times it would fail part way through. What I was in fact encountering was a timer firing and searching for connected printers while the app was in the middle of sending data to a printer. While this behavior was perfectly acceptable in communication for WiFi printers (TCP supports multiple simultaneous connections), it totally broke down in the new communication channel. It became clear that some kind of mutual exclusion was necessary to prevent this kind of collision.
Overall, this is a great printer. I can’t complain about the price because for similar thermal printers, this is relatively cheap. Any cheaper and there are issues with printing mechanics and whatnot.
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. 
First one we got was dead. Customer service is almost non-existent. Packaged it up and paid to ship back to repair center. Several weeks went by with no feedback, then received back the exact packaging with no note or anything to indicate what the issue was, or if it had even been fixed. It seems it has, but that process was a pain. Now it doesn’t like to stay visible on the network so we are always either re-booting or just telling people it’s broken. Turns out people don’t care all that much about paper receipts anyway. Recommend purchasing directly through Square if you really need it. At least then you might get some tech support.
I am sure that this has been asked and answered, but the search feature on this communities site is not very robust and the information I’ve been able to gather from square/communities is not entirely clear. So I am asking again (maybe).

Bought this strictly to print receipts with the Amazon Local Register iPad App and card reader, as it is the only receipt printer supported at this time by that platform. (Bought it used via an Amazon re-seller; works perfectly. It was easy to set up on the network using the downloadable Windows software. Once set up, my iPad and the Amazon Local Register app found the printer and linked to it easily. I haven’t tried using any of the other options (like printing our logo or printing coupons), but for what I bought it for it works perfectly. It prints extremely fast and clearly. The cutter works well, too. It is nice that it can be mounted to a vertical surface if desired.

Bluetooth printing was a great project — it brought many unique engineering challenges and taught me a lot about how Square’s code base works. I’ve always been taught to use inheritance when possible to organize and share code, but working with the peripheral class hierarchy was a strong reminder of just how valuable a good, well-organized, object-oriented architecture can be. There was a lot of shared code between WiFi and Bluetooth printers that I could have copied and pasted, but I’m glad that I took the time to not just make it work, but to do it right. I’m thankful that my co-workers pushed me to take the time to experiment with different abstractions of concurrency. Not only is my code better, but I now know many ways to approach the problem. In software, there’s rarely just one solution, and this is a good reminder to explore every possibility before choosing one — because it was the first idea that seemed to work.

Includes, Square reader, Star Ethernet Printer, APG 13″ Vasario Cash Drawer, drawer cable, extra 2 rolls of thermal receipt paper and installation support. 
The printer is great and works as described, but the product description is misleading. It says that it is a bluetooth printer AND cash drawer, which would imply they both are bluetooth. In the extra bullet points it further states its not a usb cash drawer (which would lead one to believe it was bluetooth because nothing else works with Square). What they send is a cash drawer that connects via a phone jack cable. This is not stated anywhere in the description. I needed a bluetooth cash drawer to go with the bluetooth printer and my wireless computer system. It also advertises that it is for a SQUARE POS system. Well, that uses USB or bluetooth. NOT A STUPID PHONE JACK CABLE!! I looked all over for what I thought this was and find it isn’t! Very disappointed. Now what do I do with a useless cash drawer? Oversize paperweight?
The rest of the peripheral library code was also reusable. Admittedly, our deep class hierarchy was rather intimidating when I first came to Square, but it ended up being possibly my greatest resource in writing this feature. At the highest level, Register has a Peripheral class to model every hardware device we support. It includes common properties like manufacturer name, model name, and its connection state. At the next level down is the Printer class, which encapsulates printer-specific information like the kind of data it can print and its print width, as well as abstract methods for printing images and text. Having this infrastructure in place made the design of the Bluetooth printer class clearer, and provided a clean, generic API for the rest of the app to use to print images and text to any printer, leaving the low-level details of the printer communication to the subclasses.
I’m a software engineering intern at Square and have been working on Bluetooth printer support for iPad. This feature was released in our latest Square Register build and brings physical receipt printing using Star printers to a mobile customer base. Before this version, Register for iPad supported printed receipts through Star printers connected by WiFi and USB. Adding support for a new type of printer was a great choice for an intern project as it was a combination of building off of an existing hardware integration layer and extending it to support new concurrency requirements. Integrating this new feature into Square’s codebase was a great lesson of how a well-designed code base can make writing new code easier.

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.
