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.

Great product and great company to work with. I at first ordered the TSP143U which is a USB Printer to work with a Tablet to set up a POS system at my business. Once I got it, I realized that if I had the printer plugged into the tablet there was no additional port to then charge the tablet. I contacted the company and they gladly accepted my return and let me reorder this LAN Printer. I highly recommend this vendor and their product.
The Star Micronics SM-S230i is light weight at only 7.7 ounces. It is small and easy to carry around. If you’re someone who sell at a farmers market, craft fair or some other place where mobility is very important, the Star Micronics SM-S230i may be what you need. It uses thermal paper and connects to your iPhone, iPad with bluetooth or USB. ​Here is the user manual for the Star Micronics SM-S230i.
I do not nor do I need a receipt printer. All I want is a USB cash drawer that costs less than $235. Square, if you’re reading this, please add support for a wider variety of USB cash drawers. Your focus is small businesses. Not sure why you have only the most expensive cash drawer (more than 2x the Price of the Square Stand) as the only USB one supported). Surely it can’t be that hard to come up with new drivers?
Please help! I ordered a pos hardware bundle from Walmart.com and it’s not recognized by My square stand! Is there a way of “tricking” square stand into recognizing my usb receipt printer and cash drawer?
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).
The STAR MICRONICS SM-T300I is also a light weight receipt printer. But it’s very durable and rugged. It’s also Apple MFi certified for iOS phone and iPads. It also works with Android and Windows. It’s been tested to take a little bit of beating and is used by people who are outside a lot. Having said that the price is higher than other printers. If you need something rugged, this device may be the one for you. But if you don’t. You will want to look at something else as this device can get expensive. The SM-T300i is easy to use. There is a well written and very detailed user manual. The user manual gives details on how to configure the receipt printer and how to load paper. Here is a link to the Star Micronics SM-T300i User Manual.

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.

I looked around for a hardware bundle for my Square POS setup and ultimately went with this combination. Very pleased with the product and the seller’s follow up was excellent. They answered several of my questions quickly and over the holiday weekend.
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 kept the static method I’d written for having a single, unique lock and changed it to create a single, unique dispatch queue. The static method, however, introduced a new issue I’d overlooked: upon logging out of the app, the queue would persist while the code blocks it ran tried to access deallocated data. This new issue finally pushed me to use an even higher level concurrency abstraction, NSOperationQueue (see Apple’s documenation for more details). NSOperationQueues are built on top of GCD but provide several extra features, including the ability to cancel operations. Moving printer communication code to an NSOperation subclass was a small amount of extra work that paid big dividends. By storing the operation queue as an instance variable on the print controller, I was able to cancel all waiting printing and printer discovery operations and deallocate the queue itself in just a few lines of code.
We recommend using the Square contactless and chip reader for a fast, seamless payment experience on all devices – not just those without a headphone jack. To accept magstripe-only cards, or gift cards, we recommend using the Apple Lightning to Headphone Jack adapter (included with the iPhone 7) to connect your Square magstripe reader. You might also try a third party USB-C to 3.5mm audio adapter, but please note that Square has not officially tested compatibility between the magstripe reader and other third party adapters.
First and foremost, a little background info: I own my own business and have been using the Square Register POS system for over four years. I have a different kit, but they’re all similar products. When my friends decided to open their restaurant, they went with an old school cash register and struggled at the end of the night with keeping track of taxes because it was not as intuitive to use. I convinced them to order this kit from Amazon and the other necessary items elsewhere and helped them set everything up in less than 30 minutes. This kit provided an excellent, trusted printer and an easy to connect cash drawer. Upon arrival, I had an issue with the cash drawer – it would not open. A quick email (on a Sunday) to the seller, and he gave me advice and a link to an explanation as to how to fix the stuck drawer. Using his explanation took me a couple of minutes to fix it. I am a realistic person, and I understand that things don’t always go as planned, so I was happy the seller worked with me fast to come to a solution. I gave this five stars because of the customer service – you can find similar products elsewhere and they all work the same way… but the customer service provided made this an excellent purchase! Thanks EOM-POS!
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.
Implementing Bluetooth printing introduced new limitations in parallel processing and communication that required me to rethink how we manage concurrency in our printing system. If you’re familiar with multi-threaded code, you probably already realize that expensive operations, such as peripheral communication, downloading and uploading, and heavy computation, are best run asynchronously off the main UI thread. In our code for WiFi printing, this is done using the most basic functionality of Grand Central Dispatch (GCD), one of Apple’s built-in mechanisms for managing concurrent tasks. For more detailed info about GCD, read Apple’s documentation . Each print operation and printer discovery operation is added to a global concurrent queue that runs the code on a private thread, abstracting away the mechanics of threading. The result of this is that the different operations are allowed to run in parallel with no restraints and no control.

I do appreciate your post though and I wanted to let you know that we are working to provide support for more printers and your feedback is welcome! For example, we recently launched support for several Epson printers which can be used with Square on iOS devices (the full list of printers is here). 
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. 
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.
This video takes a look at which receipt printers you can use with Square and the Square Stand with iOS, and which printers are best for your business. The USB printers can ONLY print with the Square Stand. We go over the TSP100, TSP100ECO, TSP100III, SM-S220i, and SP700. For more information on these printers, see our Square Compatible Receipt Printers article: https://posguys.com/blog/product-info…
