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.
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.
Square Point of Sale on an iPad is compatible with a wide variety of third-party hardware accessories. Below, you’ll find a list of supported accessories, where to purchase them, and information on getting set up.

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.

I have my own iPad 2 and square stand. I was Looking for compatible hardware and this was excellent. The register and printer work great, I even ordered more papers for the printer so we will use it long term.
@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! 
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”.
Unless proven otherwise, I agree.  And in my business, giving a client a receipt on what amounts to a piece of adding machine paper is unprofessional.  I should be able to use any printer that is compatible with the iPad, not just the uni-tasker receipt printers.
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.
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 don’t have any personal use of this but this item says it takes usb input and converts it to the connection that would come out of the printer from what I understand.  It may work, it may not.  There are no reviews that are helpful of the product.
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.

Had 3 of these in my place to on cash draws one in the kitchen they work well as long as there is no internet/WiFi drop off. Using it with couple IPad Airs and Square register app for several years. When I loose internet or sometimes they seem to disconnect from the register even when I don’t have internet problems and they usually have to powered off and on. Also in the mean time my cash draw wont open and I have to find the key. Being so annoyed I with connection issues I have since replaced them with the USB versions (except the kitchen one) and all my problems stopped.

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. 
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.
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.
@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. 
As a bluetooth only device, it is a bit glitchy. If you are wanting to use it with a phone/tablet only as a standalone device, look elsewhere. The miura m010 reader works great for this, though is unfortunately not available on amazon.

EOM-POS Heavy Duty Cash Register Money Drawer + Mounting Brackets for Under Counter Installation. Compatible with Square Stand [Receipt Printer Required]. Built in cable to connect to receipt printer.
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.
The Ethernet printers compatible with Square Point of Sale 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. 
With resistance to the most brutal environments, APG drawers feature sturdy steel frames powder coated in cloud white or black to resist scratches and other external abuse. Industrial grade steel ball bearing slides on the drawer won’t wear like silicon wheels and promote silky smooth opening and closing every time.

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.

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
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.

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.
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.
You can use any of our Square Compatible Receipt Printers with the Square Stand Hardware, this setup has the most options to choose from. It just depends how you want to connect to the Square Stand and how many stations you have. If you are connecting straight to the Square Stand via the USB hub, or with Bluetooth we offer the following Thermal Printers for printing Credit Card Receipts :
