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…
USB receipt printers can be used to print customer receipts, order tickets, and order ticket stubs. USB printers connect to Android devices via a USB OTG (On-The-Go) adaptor. Make sure your device supports USB OTG or USB Host mode.
If your customer entered an email address to receive a receipt from a Square merchant in the past, they may already be opted in to automatic receipts. These customers won’t be asked to enter their contact information after a sale, and a receipt will automatically be sent to their preferred email address.

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.
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.
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. 
I already had the square reader and just was tired of it being in other spots or being charged. The dock was a great addition to the square stand and the printer. Very easy to use. Just attach to the square stand and put the reader in. The dock has weight to it so i dont have to worry about it falling especially in the spot i put it. Definitely reccomend
This is one of the more common receipt printers used with Square Payments. It generally costs less than $200. It come in white and black color. It has an auto-cutter to slice receipt paper for you. It uses thermal paper so you never never need to fill it with ink. It is generally easy to maintain and add paper when you need it. So this is a printer that works well in a wide variety of environments. However, if you are in a kitchen or some area where the air is moist you may want to get an impact printer as thermal paper does not work well in moist environments where there is little ventilation. ​Here is the user manual for the Star Micronics SM-S230i.
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:
September 30, 2016 • Android Receipt Printer • Mobile Bluetooth Receipt Printer • Refurbished Thermal Printer • Square Compatible Receipt Printer • Square Hardware Bundle • Square Kitchen Order Printer • Square Stand Printer
If you are using your iPad or iPhone by itself with the Square app, you will not be able to use a USB Star Micronics Printer. You will need either a Bluetooth Receipt Printer, or Ethernet Receipt Printer. A good reason for going with Ethernet, is that you can have multiple devices print to one printer. If you are using an Android device, you can use either an Ethernet Receipt Printer, or and of the USB Receipt Printer stated above as long as you use the USB OTG(on the go) adapter. Please note, Bluetooth is not currently supported on Android for Square. 
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?
My first inclination, having just taken a class in C++ using pthreads, was to simply use locks. I created a shared NSLock through a class method and locked before listening and printing, as described in Apple’s Threading Programming Guide. I was excited when it accomplished the mutual exclusion I wanted, but my coworkers were less thrilled about using such a low-level solution given the higher level abstractions available in iOS. In search of a higher-level solution, I replaced the global concurrent queue on which I was running the printer code with a serial dispatch queue, allowing only one block to be run at once. I was getting warmer, but my new solution still raised some concerns.
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.
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.
Did you just purchase a Square Stand or have the Square Register app running on your Android, iPhone or Tablet and need a Receipt Printer or Cash Drawer Hardware Bundle? There are a few different models and options for you to choose from when selecting a Thermal or Impact Receipt Printer and we will go over these here. We will cover other popular POS apps like Shopify, Breadcrumb, Shopkeep, PayPal Here and Clover in upcoming articles.
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.
The Ethernet printers compatible with the app 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.

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.
If you want a small and easy to carry receipt printer, this may be it. It weighs less than half a pound. It is easy to carry around. For people who sell at craft shows, farmers markets and historical fairs this may be the receipt printer.
It supports 58mm width thermal paper printing, with high printing speed, clear printing & low noise. You can connect your devices with the printer via BT 4.0 & 3.0, USB cable or serial port line. Prin…
The Square app is compatible with a wide variety of third-party hardware accessories. Below, you’ll find a list of supported accessories for Android devices, where to purchase them, and information on getting set up. 
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.
If you accept credit card payments from your customers at your place of business, you’ll want a receipt printer. A receipt printer automatically prints a receipt for your customer when they make a purchase.
@usascottwright – While we don’t currently support Epson printers, it’s definitely a popular feature request. I’ll update this thread if that changes in the future! Also, apologies for the delay in following up with you. 
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.
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 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.
