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.
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!

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.
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.
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.
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.
First one we got was dead. Customer service is almost non-existent. Packaged it up and paid to ship back to repair center. Several weeks went by with no feedback, then received back the exact packaging with no note or anything to indicate what the issue was, or if it had even been fixed. It seems it has, but that process was a pain. Now it doesn’t like to stay visible on the network so we are always either re-booting or just telling people it’s broken. Turns out people don’t care all that much about paper receipts anyway. Recommend purchasing directly through Square if you really need it. At least then you might get some tech support.
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.

@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! 
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.
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.
Another nice touch is that they include a CD which allows you to customize the printer (add logos, sync with POS systems, custom data to add once the receipt is printed, etc). Keep in mind though, this customization works with certain POS systems, not all. On Square, I can’t tell the printer to print out all of the extra stuff since the POS for Square is very simplified.

Hi @McNabbGames — I went ahead and combined your thread with another seller’s who had a similar question. I can assure you that we’re always looking into more affordable hardware options for our sellers. As for the technical explanation, from my limited understanding (I’m not an engineer), each printer manufacturer has a specific driver for their hardware, and since manufacturers don’t build printer drivers for Square Register, we would have to build one for each printer model – which is something we don’t have the bandwidth to do.

@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’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.
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.
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).

Bluetooth printing was a great project — it brought many unique engineering challenges and taught me a lot about how Square’s code base works. I’ve always been taught to use inheritance when possible to organize and share code, but working with the peripheral class hierarchy was a strong reminder of just how valuable a good, well-organized, object-oriented architecture can be. There was a lot of shared code between WiFi and Bluetooth printers that I could have copied and pasted, but I’m glad that I took the time to not just make it work, but to do it right. I’m thankful that my co-workers pushed me to take the time to experiment with different abstractions of concurrency. Not only is my code better, but I now know many ways to approach the problem. In software, there’s rarely just one solution, and this is a good reminder to explore every possibility before choosing one — because it was the first idea that seemed to work.

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.
Receipt Printer Compatible With Square, A cash drawer needs to be linked to an invoice printer to open immediately. Otherwise, you’ll have to buy hand open the drawer utilizing the money drawer secret. * This standard money drawer is not able to link to an invoice printer.
Edit to say that the network issues I mentioned were tied to the wireless router we were using. Replaced that piece and the printer started working great. I still recommend purchasing as a package for better price and customer service, but not a bad piece of equipment.

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. 
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.
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.
