I use these things every day (I work retail). We use Star TSP700 [Mk I or Mk II] printers with CUPS. The PPD files are available for download from the Star Micronics website. Some of my time is spent hacking the PPDs to adjust paper sizes, resolution etc, but at least I have that option. The printers have an ethernet port, and some of them come with USB.

Was setting up CUPS to work with these printers difficult? And also how painful was it to get the printers on the network reliably? Potentially, I would have to install these printers in hundreds of coffee shops that all have different internet configuration. I need to make myself an expert in this, but I'm not sure where to start. Thanks M0nty

 I could send you info by email if you like - my email is in my profile. Our stores have a server on-site, and various printers and till receipt printers, not all of them attached to tills. The proprietary app we use creates a PDF, which then gets sent through to CUPS (see https://wiki.linuxfoundation.org/en/OpenPrinting/Database/CUPS-Filter-Chart https://wiki.linuxfoundation.org/en/OpenPrinting/Database/CU... for clues on this). If you're sending a data stream from a central server to a till printer in a store (i.e. the raw printer data is going from a centralised CUPS) that might work, depends on the broadband link. Once the printers are on the network, they tend to stay that way. The only problem is, they have to be set up using Reverse ARP which is a bit shaky, but once you're used to the procedure it's OK.

 The setup I'm trying to achieve is minimal. On site, there would only be a printer which is connected to the internet via ethernet port (or wireless). From off site, I want to send an http request to the printer (As an aside, I'm trying to make the request secure somehow). The http request would look something like this ideally: curl -X POST --data-urlencode 'html=<html><head><meta charset="utf-8"></head><body>YOUR MESSAGE HEREYOUR EMAIL</body></html>' http://remote.bergcloud.com/playground/direct_print/Q9UCCLRTY6EL http://remote.bergcloud.com/playground/direct_print/Q9UCCLRT... So I wouldn't have the luxury of having an on site server unfortunately. PS - I couldn't find your email in your profile. It was empty when I clicked through.

 Email sent, I hope.

 If I get what I think you are trying to achieve, I don't think it is possible with just a printer. 1) You'll need some hardware to act as a webserver that can turn the HTTP requests into something the printer understands. Printers don't really have webservers built in to them with HTTP APIs. 2) Firewalls will be a problem even if you have a dedicated webserver. Most likely you'll add some hardware that connects to a central service as a client, and your central service will relay messages down to your device on site.
