*Note: We have had some Sellers complain about the receipts printing over too many pages when they want it to only print on one. The trick is to reduce the scale of the image within your printing options until it fits. (see screenshot)
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.

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.
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.

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.

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.
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.

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.

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.
This printer is terrible. It always has connectivity issues and it is constantly jamming. Worst mistake i made for my business. We have to keep it off until we get a customer otherwise it keeps printing no host receipts and it jams. Called star micronics they said it was probably an issue on my end. WRONG! MY other register, which is hooked up by same switch board, has an Epson printer and it gives no issues. Do not buy this printer for your business. Go with an Epson. Same amount of $, no problems.
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.

Last but not least, though I’m enough of a geek that the code itself would have been interesting and fun for me, it was really special getting to see first-hand how the product truly helped people. Meeting a merchant who had previously only been able to give out handwritten receipts, handing her a Bluetooth printer, and seeing how our new feature would make her job easier was the highlight of my summer.
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.
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.

@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.
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.
