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.
Connect your Square Stand with a compatible iPad and recommended hardware accessories to help run your business. Before purchasing a Square Stand, make sure you’re using a supported iPad. You can identify your iPad model on Apple’s Support site.
@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. 
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.
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.

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.
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!

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.
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.
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.

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. 
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.

@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! 
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…
Here is more information.

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).
