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 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.
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.
I don’t have any personal use of this but this item says it takes usb input and converts it to the connection that would come out of the printer from what I understand. It may work, it may not. There are no reviews that are helpful of the product.

With resistance to the most brutal environments, APG drawers feature sturdy steel frames powder coated in cloud white or black to resist scratches and other external abuse. Industrial grade steel ball bearing slides on the drawer won’t wear like silicon wheels and promote silky smooth opening and closing every time. The heavy duty latch mechanism is rated for over 4 million operations, allowing you to open the drawer 200 times a day, every day, for nearly 55 years.
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.

Bought this strictly to print receipts with the Amazon Local Register iPad App and card reader, as it is the only receipt printer supported at this time by that platform. (Bought it used via an Amazon re-seller; works perfectly. It was easy to set up on the network using the downloadable Windows software. Once set up, my iPad and the Amazon Local Register app found the printer and linked to it easily. I haven’t tried using any of the other options (like printing our logo or printing coupons), but for what I bought it for it works perfectly. It prints extremely fast and clearly. The cutter works well, too. It is nice that it can be mounted to a vertical surface if desired.
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.
Everything you need to get started taking in orders and money (except the iPad and the cash for the till!). Includes, Square credit card reader, receipt printer with Ethernet interface, 2 rolls of receipt paper, 13″ wide cash drawer with till, and all cables for connecting the printer and cash drawer.
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.

You may plug a receipt printer into one of the three USB ports found on the Square Stand accessories hub, but kitchen printers are typically located some distance away from your checkout register – farther away than a USB cable will reach.
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.
