@usascottwright – While we don’t currently support Epson printers, it’s definitely a popular feature request. I’ll update this thread if that changes in the future! Also, apologies for the delay in following up with you. 
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.

I have my own iPad 2 and square stand. I was Looking for compatible hardware and this was excellent. The register and printer work great, I even ordered more papers for the printer so we will use it long term.
You can add your logo and text to your receipt. This is done with software that is included with the receipt printer. By adding your logo to your receipts you have a place to advertise your business. You can also put your phone number on your receipt or your website URL. This is a good thing to do if you’re selling at a craft show, fair, farmers market and etc. The customer may not remember your name and may not go online to search for your website. But if you put your website on the receipt you have a better chance of the customers visiting your website to make a purchase.
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.

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.
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.

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/
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.
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.

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:
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.

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).
We recommend using the Square contactless and chip reader for a fast, seamless payment experience on all devices – not just those without a headphone jack. To accept magstripe-only cards, or gift cards, we recommend using the Apple Lightning to Headphone Jack adapter (included with the iPhone 7) to connect your Square magstripe reader. You might also try a third party USB-C to 3.5mm audio adapter, but please note that Square has not officially tested compatibility between the magstripe reader and other third party adapters.
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.
If my answer solved your problem, would you mind marking it as “Best Answer”? That’ll help the rest of the community find what they’re looking for. If not, just write back, and I’ll continue to help. Thanks!
Hi @McNabbGames — I went ahead and combined your thread with another seller’s who had a similar question. I can assure you that we’re always looking into more affordable hardware options for our sellers. As for the technical explanation, from my limited understanding (I’m not an engineer), each printer manufacturer has a specific driver for their hardware, and since manufacturers don’t build printer drivers for Square Register, we would have to build one for each printer model – which is something we don’t have the bandwidth to do.
