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.
The new Square Contactless and Chip Reader is included so you can accept every way your customers want to pay. Place the reader in the dock, connect the dock to the USB hub, and you’re ready for business. Accept magstripe cards, chip cards, and NFC payments like Apple Pay.
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.
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.
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). 
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.
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.
If you have a Square Stand, in addition to the printers above, you can use certain USB interface receipt printers. The following receipt printers are only compatible with the Square Stand, not the Square card reader:
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…
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.

@SSmobile @Kevin7 – I went ahead and moved both of your comments over to the thread where we are tracking this feature request. I totally understand your frustration and desire for Epson support. They make a mean printer that is also a fraction of the cost of most Star printers. I have personally passed this feedback along to our product team, and expanding compatibility is something that is top of mind for them. I’ll update this thread if/when this functionality is added in the future! 
@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. 
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 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.
eBay determines trending price through a machine learned model of the product’s sale prices within the last 90 days. “New” refers to a brand-new, unused, unopened, undamaged item, and “Used” refers to an item that has been used previously.

The Star Micronics TSP143IIILAN works with Square Payments. Star Micronics is a well known manufacturer of receipt printers. They make many different models. You connect to a Square iPad stand with a USB cable. This receipt printer uses 80 mm width or 3 1/8 inch width thermal paper for the receipts. There is a roll of paper that ships with the receipt printer. An auto cutter mechanism cuts the receipt paper for you when you make a sale.

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”.

To create your own bar codes and labels, you’ll need to use a third-party application. At the moment, we don’t support bar code and label printers and can’t guarantee compatibility, but many customers have success using the DYMO Label Writer 450 and labels with Square.
NOT FOR USE WITH SQUARE STAND! If using a Square Stand consider the Square Stand Starter kit which has a printer that plugs into the stand. The printer in this kit must be plugged into your router.    
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.
Built specifically to work in environments where heat and humidity can erode the type on the kitchen order, the SP700 is an ideal printing solution. This fast, two-color printer offers crisp, easy to read type for quick viewing, clamshell design for easy paper loading and an embedded power supply for space efficiency.
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:

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.

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. 
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. 
You can add your logo and text to your receipt. This is done with software that is included with the receipt printer. By adding your logo to your receipts you have a place to advertise your business. You can also put your phone number on your receipt or your website URL. This is a good thing to do if you’re selling at a craft show, fair, farmers market and etc. The customer may not remember your name and may not go online to search for your website. But if you put your website on the receipt you have a better chance of the customers visiting your website to make a purchase.
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’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.
