If you are buying this for the Amazon Local Register payment platform, be sure to get the Ethernet version (not the USB version). This one only connects to your network and not directly to a computer.
Square introduces more ways to engage with customers. Square now integrates with cash drawers and receipt printers. With a single tap on an iPad, you can open your register’s drawer to complete a cash sale or make change. Please read the options below carefully before purchasing a cash drawer.
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.

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.
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.

Effect printers just print order tickets for a cooking area. They’re not impacted by heat and can stand up to warm environments. They need heat-sensitive paper and will not deal with non-thermal, invoice printer paper.
An update 11/21/15 Had it working fine with Amazon local register until Amazon shut it down, so bought the PayPal chip and card reader- the updated paypal iOs app will not print to this printer. (iOs 9.1/ iPad 3). The workaround I found was to turn this printer in to an airprint printer- it’s a bit of a hack, instructions are out there, problem being you must have a host computer on the network. To be clear- this is a PayPal issue- not a fault of the printer.

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.
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.
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).

This is an impact printer. So it makes a noise when it prints. Why would you want this? You might want it if you are in an area such as a kitchen where thermal paper receipts don’t print as well because of moisture in the area. You would not want this noise around customers. But if you have a moist area such as a busy kitchen this impact printer may be what you can use. Here is the user manual for the Star Micronics SP742ML.
Star Micronics TSP100Receipt Printer is the first All-in-One receipt printer on the market today!. The advantage of TSP143LAN Receipt Printer is evident for applications such as retail, restaurants, and convenience stores.

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.
*Note: We have had some Sellers complain about the receipts printing over too many pages when they want it to only print on one. The trick is to reduce the scale of the image within your printing options until it fits. (see screenshot)
There are several reviews of this product, and the unit is physically about the size of three iPhone 4 stacked in a neat pile. It is intended to support between 7 and 10 printers before you need to buy a second device. I am not clear whether you can set this up from iOS, but it works well once you have it set up.

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.
Atm it’s cheaper for me to use something else other than square, than to change the printer tablet setup. It appears other people have similar issues. Square managment need to grasp the economics here of only catering to a small hardware segment(Star printers) of the market, while marketing themselves as a simple DIY eftpos POS for small businesses, who burn themselves on compatability issues. Hopefully Square can solve this issue.
