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.

Receipt printers are designed to hold small paper roles, instead of vertically placed stacks of paper like one finds in standard 8.5″ by 11″ printers. Instead of connecting to a traditional keyboard, they usually hook up to a cash register or whatever device holds the business’ point of sale system. They’re usually quite compact since they sit on cluttered surfaces like the check-out area of a grocery store or the desk of a working professional.

This video, from http://www.beaglehardware.com, describes how to connect the approved printer and cash drawer to Square Register. With Square Register, you can print receipts for your customers at the counter. Connect to a cash drawer to make change for customers and store cash. The cash drawer will automatically open when connected to a supported receipt printer for every cash transaction and refund on your iPad or Android device.
Just click the Transaction and the Receipt will preview on the right-hand side. At the bottom, you’ll see the receipt number (ex: Receipt #H8R5). Click that and it will show you the digital version of the receipt. From there you’re good to print on the standard 8×11 printer paper.
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.
But my point is that an adding machine paper-receipt looks unprofessional in some businesses.  An inexpensive ink jet or better, a multitasking network office printer that is already in use would make a LOT more sense for me.  I’m sure they are robust and work fine, they just don’t suit my business and I don’t like being so limited in the TYPE of printer I can use.

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.

Many businesses understand the importance of offering promotions and discounts, so a receipt printer capable of printing coupons, too, is incredibly useful. Businesses that service a high volume of customers every day, and especially those that create long, itemized receipts should consider a model with a high paper-per-minute production rate. If the receipt printer is for a home office, where the user doesn’t want to disturb others, a person should look for a thermal printer; these are the quietest variety since they do not use any impact to create the font.

If you are using your iPad or iPhone by itself with the Square app, you will not be able to use a USB Star Micronics Printer. You will need either a Bluetooth Receipt Printer, or Ethernet Receipt Printer. A good reason for going with Ethernet, is that you can have multiple devices print to one printer. If you are using an Android device, you can use either an Ethernet Receipt Printer, or and of the USB Receipt Printer stated above as long as you use the USB OTG(on the go) adapter. Please note, Bluetooth is not currently supported on Android for Square.

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.
