Receipt printers can have several notification features that can be incredibly useful. Some models will alert the user if there has been a loss of Internet in the middle of a printing job, and others buzz to notify the user that the printing job is done. The latter feature helps keep the user from ripping out the receipt before it’s complete, and having to start all over again. There are also models with LED status lights that tell the user important information like when the ink cartridge is low.
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.

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.
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.

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.
@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. 
Receipts have been an important part of society since nearly the beginning of civilization. In 3200 BCE Samaria, Israel, temple offerings were an important part of the taxation system. People would write down symbols to represent the offerings they had made to their temples, and these acted as a form of receipt. Papyrus receipts from Egypt have been found that date back to the mid-1200s, recording purchases like cattle and grain. Some receipts at the time were chiseled onto stone, but these were inconvenient to carry around and cumbersome at best.
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.
Don’t forget, we also sell Square Compatible Hardware Bundles for all these printers that includes s Refurbished Receipt Printer and a New compatible cash drawer plus cables, paper and everything you need to get started!
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.
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.
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:

Square Point of Sale (formerly Register) is the free point-of-sale app that gives you everything you need to run and grow your business. Accept debit and credit cards with a Square Reader for magstripe, and accept EMV chip cards and Apple Pay with the Square Reader for contactless and chip. Funds are deposited fast—see money in your bank account in one to two business days. Use your point of sale system to keep track of sales and inventory in real time, manage items and employees, and view analytics about your business. All this with no long-term contracts or surprise fees.
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.
Atm it’s cheaper for me to use something else other than square, than to change the printer tablet setup. It appears other people have similar issues. Square managment need to grasp the economics here of only catering to a small hardware segment(Star printers) of the market, while marketing themselves as a simple DIY eftpos POS for small businesses, who burn themselves on compatability issues. Hopefully Square can solve this issue.
Designed to churn out more than 100 miles of printed receipts, the Pos-X Evo Green will help your business run smoothly and effectively for the long haul. It’s a powerful option, but at only six inches wide, it’s compact enough to fit on cluttered desks.
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.
It is a simple process all I can think is that square gets a percentage of royalties from their supported printer sales and thats why they are locking everything down to these ridiculously overpriced pieces of equipment. 
With your choice of one or two under till media slots, the Series 4000 makes safely storing receipts, large bills, or other important media a snap. The spacious heavy duty till features coated bill stays and stronger than average dividers, so you can be sure your money stays put.
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.

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.
There are three main types of receipt printers: Inkjet, Dot-matrix, and Thermal. Dot-matrix printers have a small printing head that moves either in an up and down or side to side motion. Like a typewriter, this printer depends on the impact of the head against the paper to produce characters. The head hits a cloth ribbon that is covered in ink, and then impresses a character onto the paper. It creates characters through a series of thousands of tiny dots, which is how it gets its name. One concern with Dot-matrix printers is that the ribbon must frequently be replaced. Inkjet printers use tiny ink guns to create their characters, instead of impact. The guns shoot little dots of ink at the paper, but the dots are so minuscule that people cannot detect them inside of the characters.

Square is not interested in using anyone but Star. And their attitude is that they frankly don’t care. I know, I have emails from them about it. If I was to guess, I would bet they have a deal with Star that funds their (insert pizza parties, to silk pockets). But lets be realistic. I mean it has to be something viable, right? The fact that Star uses the same print protocals that Epson uses has no bearing on an Epson receipt printer not working. It goes in the same line as Android devices can’t use bluetooth devices… although that new chip reader is bluetooth. It is a lack of customer service and they need to step up to the plate, or someone is going to come along and take their business away from them.
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.

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.
