Star Micronics TSP100Receipt Printer is the first All-in-One receipt printer on the market today!. The advantage of TSP143LAN Receipt Printer is evident for applications such as retail, restaurants, and convenience stores. TSP143LAN Receipt Printer is provided with all standard operating system drivers (Windows, Linux and Mac) and specialty drivers such as OPOS and JPOS. The printer is also directly supported in Square Register. Star has also included a number of embedded simple utilities that will enhance Retail or Hospitality CRM in POS applications and therefore make the entire experience simple. These printers come complete with every thing you need including printer, power supply, Ethernet cable, wall bracket and a roll of thermal paper.
As a bluetooth only device, it is a bit glitchy. If you are wanting to use it with a phone/tablet only as a standalone device, look elsewhere. The miura m010 reader works great for this, though is unfortunately not available on amazon.

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. 
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.
Please note, these printers can only be used with iOS devices at this time. I don’t have a timeline for when they’ll be supported with Android devices yet. But I’ll report back when I have an update! 😀
The STAR MICRONICS SM-T300I is also a light weight receipt printer. But it’s very durable and rugged. It’s also Apple MFi certified for iOS phone and iPads. It also works with Android and Windows. It’s been tested to take a little bit of beating and is used by people who are outside a lot. Having said that the price is higher than other printers. If you need something rugged, this device may be the one for you. But if you don’t. You will want to look at something else as this device can get expensive. The SM-T300i is easy to use. There is a well written and very detailed user manual. The user manual gives details on how to configure the receipt printer and how to load paper. Here is a link to the Star Micronics SM-T300i User Manual.
Impact printers only print order tickets for a kitchen. They’re not affected by heat and can withstand warm environments. They require heat-sensitive paper and won’t work with non-thermal, receipt printer paper. 
It supports 58mm width thermal paper printing, with high printing speed, clear printing & low noise. You can connect your devices with the printer via BT 4.0 & 3.0, USB cable or serial port line. Prin…

When you connect to the USB Receipt Printer or Ethernet Receipt Printer with the included cable, the cash drawer will open every time you complete a cash sale. Or use the included keys to manually open.
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.
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. 
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.
APG’s Stratis tablet holder is designed for mobile and tablet point of sale applications. The Stratis enables an iPad to seamlessly slide over to the customer facing side for signature approvals, while giving the cashier a firm base to work from during the transaction process. A magnetic connection between the Stratis holder and a cash drawer holds the tablet firmly in place. Available in black or white.     $125.95 Black
Have not purchased this printer, but wanted to let people know that this is not the only printer that will work with Square. I have two Star Micronics printers, one Ethernet and one Bluetooth and both work fine with the Square app for iPad. I also have Ethernet based cash drawers that connect through the printers and those works just as well. This probably has the easiest set up, but it is not the only way.
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. 
There are several reviews of this product, and the unit is physically about the size of three iPhone 4 stacked in a neat pile. It is intended to support between 7 and 10 printers before you need to buy a second device. I am not clear whether you can set this up from iOS, but it works well once you have it set up.
If you want a small and easy to carry receipt printer, this may be it. It weighs less than half a pound. It is easy to carry around. For people who sell at craft shows, farmers markets and historical fairs this may be the receipt printer.
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. 
The STAR MICRONICS TSP654IIBI is fast and easy to configure. It is Apple MFi certified. It has auto connect and so it will connect to your iPad automatically. If you want to setup your receipt printer fast, this may be one of the best options. There is no serial cable, ethernet cable or USB connection. That seems like a positive benefit. If you move around a lot or you don’t want to mess with cables the STAR MICRONICS TSP654IIBI may be want you want.
** If you are using the Square Register app, this is the USB version of the Star TSP143 Printer and must be used with the Square Stand Hardware. You will need a Star ethernet or bluetooth printer if you are using Square or a similar Point of Sale app with the tablet or device by itself.

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?
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.
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.
First one we got was dead. Customer service is almost non-existent. Packaged it up and paid to ship back to repair center. Several weeks went by with no feedback, then received back the exact packaging with no note or anything to indicate what the issue was, or if it had even been fixed. It seems it has, but that process was a pain. Now it doesn’t like to stay visible on the network so we are always either re-booting or just telling people it’s broken. Turns out people don’t care all that much about paper receipts anyway. Recommend purchasing directly through Square if you really need it. At least then you might get some tech support.

Ethernet invoice printers can be utilized to print consumer bills, order tickets and order ticket stubs. Ethernet-interface printers are best for fixed usage and aren’t developed to be mobile.The Ethernet printers suitable with Square Register are thermal printers. They need heat-sensitive paper and will not deal with non-thermal invoice paper. These kinds of printers aren’t perfect for kitchen areas or high-temperature workspace.
I do appreciate your post though and I wanted to let you know that we are working to provide support for more printers and your feedback is welcome! For example, we recently launched support for several Epson printers which can be used with Square on iOS devices (the full list of printers is here).

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.
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.
