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.
If your customer entered an email address to receive a receipt from a Square merchant in the past, they may already be opted in to automatic receipts. These customers won’t be asked to enter their contact information after a sale, and a receipt will automatically be sent to their preferred email address. 
Overall, this is a great printer. I can’t complain about the price because for similar thermal printers, this is relatively cheap. Any cheaper and there are issues with printing mechanics and whatnot.
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.
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.

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…

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.

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.

This printer is fast. Thermal printers print very fast, and the internals are actually much simpler than the ones at my work. You simply open it up, drop the paper inside (yes, it’s a drop in, which makes it much easier to replace the roll once it has run out) and then feed the paper over the top.
Please help! I ordered a pos hardware bundle from Walmart.com and it’s not recognized by My square stand! Is there a way of “tricking” square stand into recognizing my usb receipt printer and cash drawer?
iPad-based POS (Point of Sale) systems have become increasingly popular. In addition to saving money on upfront costs, these systems have streamlined operations in the modern merchant and Square Register is quickly becoming one of the most convenient and coolest ways for small businesses to process transactions. Tablet and smartphone based systems are also being increasingly used for inventory control – from the retail floor to the warehouse – and by sales personnel assisting customers in-store and on the convention floor. The hardware options for Square Stand differ from those below. For Square Stand hardware options, or to learn how to set up hardware with Square Stand, click here: here.
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.
If you are buying this for the Amazon Local Register payment platform, be sure to get the Ethernet version (not the USB version). This one only connects to your network and not directly to a computer.

If you have a Square Stand, in addition to the printers above, you can use certain USB interface receipt printers. The following receipt printers are only compatible with the Square Stand, not the Square card reader:

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:
EOM-POS Heavy Duty Cash Register Money Drawer + Mounting Brackets for Under Counter Installation. Compatible with Square Stand [Receipt Printer Required]. Built in cable to connect to receipt printer.
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.
