Hello, I have created a POS (Point of Sales) module, then in that module I want to make it so that the cashier can print directly to the Epson TM-U220 printer.

How do I get from the browser (Firefox, Chrome, Opera) the client / cashier can print directly to the printer,

and using what, is it Applet or qr-print?

Thank you for the advice

First this is not a ZK related question ... so once you found a documented solution that works without ZK this forum can help to integrate it into a ZK application e.g. using ZK's client API.

So here my opinion maybe helping to find a technically feasible solution for your environment.

Unfortunately Java Applets are NOT widely supported in browsers anymore, you'll have a tough time getting them to work and I'd rather not count on that technology, unless I really knew that this works. Still if you have a working scenario without ZK we can help how to integrate and control this in a ZK application.

After a few searches it sounds like the ePOS-Print API might be a better fit for a web application. I found this guide containing an example project. In case your printer supports this API then a purely JS based integration will be straight forward to integrate, provided it works on a plain html/js page already.

https://files.support.epson.com/pdf/pos/bulk/tm-iepos-printumenrevk.pdf

Page 222 mentions "TM-U220" so it sounds to be supported.

good to hear, I hope the ePOS Print API works as intended. As said, in case of ZK related integration issues, don't hesitate to get back here, I'll watch the ticket.
