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.

I have a friend who runs a small shop and knew the Esky ES-CD01 Heavy Duty RJ-12 Key-Lock Cash Drawer would be perfect for his application. This drawer was a massive upgrade to the system he had been using. He had tried other drawers with different connections and designs, however this one was really the best.

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.
Bluetooth printing was a great project — it brought many unique engineering challenges and taught me a lot about how Square’s code base works. I’ve always been taught to use inheritance when possible to organize and share code, but working with the peripheral class hierarchy was a strong reminder of just how valuable a good, well-organized, object-oriented architecture can be. There was a lot of shared code between WiFi and Bluetooth printers that I could have copied and pasted, but I’m glad that I took the time to not just make it work, but to do it right. I’m thankful that my co-workers pushed me to take the time to experiment with different abstractions of concurrency. Not only is my code better, but I now know many ways to approach the problem. In software, there’s rarely just one solution, and this is a good reminder to explore every possibility before choosing one — because it was the first idea that seemed to work.
1. Receipt Printer Connection: If the cash drawer is connected to the receipt printer: Whenever you print a receipt, the printer also sends a “drawer open” signal to the cash drawer and your cash drawer will open automatically.

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.
Unless proven otherwise, I agree.  And in my business, giving a client a receipt on what amounts to a piece of adding machine paper is unprofessional.  I should be able to use any printer that is compatible with the iPad, not just the uni-tasker receipt printers.
Built specifically to work in environments where heat and humidity can erode the type on the kitchen order, the SP700 is an ideal printing solution. This fast, two-color printer offers crisp, easy to read type for quick viewing, clamshell design for easy paper loading and an embedded power supply for space efficiency.
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.

I am sure that this has been asked and answered, but the search feature on this communities site is not very robust and the information I’ve been able to gather from square/communities is not entirely clear. So I am asking again (maybe).
First and foremost, a little background info: I own my own business and have been using the Square Register POS system for over four years. I have a different kit, but they’re all similar products. When my friends decided to open their restaurant, they went with an old school cash register and struggled at the end of the night with keeping track of taxes because it was not as intuitive to use. I convinced them to order this kit from Amazon and the other necessary items elsewhere and helped them set everything up in less than 30 minutes. This kit provided an excellent, trusted printer and an easy to connect cash drawer. Upon arrival, I had an issue with the cash drawer – it would not open. A quick email (on a Sunday) to the seller, and he gave me advice and a link to an explanation as to how to fix the stuck drawer. Using his explanation took me a couple of minutes to fix it. I am a realistic person, and I understand that things don’t always go as planned, so I was happy the seller worked with me fast to come to a solution. I gave this five stars because of the customer service – you can find similar products elsewhere and they all work the same way… but the customer service provided made this an excellent purchase! Thanks EOM-POS!

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.
NOT FOR USE WITH SQUARE STAND! If using a Square Stand consider the Square Stand Starter kit which has a printer that plugs into the stand. The printer in this kit must be plugged into your router.

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.
