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.
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.

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.
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.
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.

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.
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.

Pay Pal says this is compatible, but the few reps I have spoken with are not really familiar enough to guide me through. My LG Optimus phone runs T-Mobile 4g. I connected stand alone router(LAN?) to printer. I am guessing there is a conflict and I need to disconnect 4g or whatever wifi is connected to phone in order to pick-up signal from LAN router, assuming I can’t receive two simultaneous signals. That would disconnect me from Pay Pal transaction. Don’t know what I missing,but so far it’s a lot of wasted time and money. There’s no customer service that I can find with printer and the user guide is scant. I’ll take another look at Star website, but don’t expect to find a solution there. A USB connection would have likely prevented many issues/

Effect printers just print order tickets for a cooking area. They’re not impacted by heat and can stand up to warm environments. They need heat-sensitive paper and will not deal with non-thermal, invoice printer paper.
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.
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.

With the Square Stand system, you can use either a cash drawer that plugs into the receipt printer, or one that plugs into the USB block of the Square Stand. Choose the method that suits your business best – but we typically recommend using the receipt printer connection, since this is simpler and far less expensive than the USB version. Note that all cash drawers listed below have special money trays configured for Canadian currency.
I do not nor do I need a receipt printer. All I want is a USB cash drawer that costs less than $235. Square, if you’re reading this, please add support for a wider variety of USB cash drawers. Your focus is small businesses. Not sure why you have only the most expensive cash drawer (more than 2x the Price of the Square Stand) as the only USB one supported). Surely it can’t be that hard to come up with new drivers?
I haven’t yet seen a receipt printer that is airprint compatible though, allowing more apps to use it. While credit card acceptance and sales apps would obviously benefit, I can imagine a number of other uses for a small printer that prints bits of disposable information. The daily forecast, sudoku puzzles, today’s schedule, todo lists, etc, for those who have to share their iPad with a spouse or children, for instance.

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.
