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.
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.    
EOM-POS Thermal Receipt Printer- USB, Ethernet, Serial Ports- Auto Cut – Cash Drawer Port (RJ11/RJ12)- Paper Width 3 1/8″ (80mm) – NOT COMPATIBLE with Mac, Square, Shopkeep, Clover, Shopify, or Paypal
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/
If you are buying this for the Amazon Local Register payment platform, be sure to get the Ethernet version (not the USB version). This one only connects to your network and not directly to a computer.
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.

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.
Edit to say that the network issues I mentioned were tied to the wireless router we were using. Replaced that piece and the printer started working great. I still recommend purchasing as a package for better price and customer service, but not a bad piece of equipment.
This video, from http://www.beaglehardware.com, describes how to connect the approved printer and cash drawer to Square Register. With Square Register, you can print receipts for your customers at the counter. Connect to a cash drawer to make change for customers and store cash. 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.
Be sure the printer and the iPad are connected to the same network. To confirm this or change your Wi-Fi network, go to the iPad’s Settings and tap “Wi-Fi” located in the left sidebar. Then select the network that the router is broadcasting and click “Connect”.
To create your own bar codes and labels, you’ll need to use a third-party application. At the moment, we don’t support bar code and label printers and can’t guarantee compatibility, but many customers have success using the DYMO Label Writer 450 and labels with Square.
The new Square Contactless and Chip Reader is included so you can accept every way your customers want to pay. Place the reader in the dock, connect the dock to the USB hub, and you’re ready for business. Accept magstripe cards, chip cards, and NFC payments like Apple Pay.

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.

You can use any of our Square Compatible Receipt Printers with the Square Stand Hardware, this setup has the most options to choose from. It just depends how you want to connect to the Square Stand and how many stations you have. If you are connecting straight to the Square Stand via the USB hub, or with Bluetooth we offer the following Thermal Printers for printing Credit Card Receipts :
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! 😀
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. 
But my point is that an adding machine paper-receipt looks unprofessional in some businesses.  An inexpensive ink jet or better, a multitasking network office printer that is already in use would make a LOT more sense for me.  I’m sure they are robust and work fine, they just don’t suit my business and I don’t like being so limited in the TYPE of printer I can use.

@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. 
If you accept credit card payments from your customers at your place of business, you’ll want a receipt printer. A receipt printer automatically prints a receipt for your customer when they make a purchase.

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
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.

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.
*Note: We have had some Sellers complain about the receipts printing over too many pages when they want it to only print on one. The trick is to reduce the scale of the image within your printing options until it fits. (see screenshot)
The rest of the peripheral library code was also reusable. Admittedly, our deep class hierarchy was rather intimidating when I first came to Square, but it ended up being possibly my greatest resource in writing this feature. At the highest level, Register has a Peripheral class to model every hardware device we support. It includes common properties like manufacturer name, model name, and its connection state. At the next level down is the Printer class, which encapsulates printer-specific information like the kind of data it can print and its print width, as well as abstract methods for printing images and text. Having this infrastructure in place made the design of the Bluetooth printer class clearer, and provided a clean, generic API for the rest of the app to use to print images and text to any printer, leaving the low-level details of the printer communication to the subclasses.
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.
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.
The printer is great and works as described, but the product description is misleading. It says that it is a bluetooth printer AND cash drawer, which would imply they both are bluetooth. In the extra bullet points it further states its not a usb cash drawer (which would lead one to believe it was bluetooth because nothing else works with Square). What they send is a cash drawer that connects via a phone jack cable. This is not stated anywhere in the description. I needed a bluetooth cash drawer to go with the bluetooth printer and my wireless computer system. It also advertises that it is for a SQUARE POS system. Well, that uses USB or bluetooth. NOT A STUPID PHONE JACK CABLE!! I looked all over for what I thought this was and find it isn’t! Very disappointed. Now what do I do with a useless cash drawer? Oversize paperweight?
