How to print a check on the fiscal registrar from a browser?

Question

css

There is an order accounting system for the company, with a web interface. And there is a task to print checks for these orders, and it is through the fiscal registrar (any one can be). With simple receipt printers, everything is pretty clear - it's just a printer, but with a registrar, you can't figure out how to do the integration. There are two ideas so far: either communicate via ActiveX (there is one example of more or less successful integration), but this immediately limits the browser to one IE. Or - a Java applet that will act as an intermediate link between the registrar driver and the system.
Maybe someone had a similar experience, tell me, please, in which direction to dig?

Answer 2

Answer 3

no way, wrapping around an arbitrary picture is impossible, because any picture is a square

Answer 4

Break the gray figure into several pictures (horizontal stripes).

Answer 5

A local server program on localhost that accepts print commands.

Answer 6

I know one (rather large) project where the second option is used: a Java applet is written, which acts as an intermediary between the driver and Javascript. And in Javascript, a wrapper is written that passes calls to the applet. Everything has been working for more than a year, and there are no problems (like) any.
I can’t share the implementation details, because I don’t understand Java at all, and all the code was written by another developer. But there is quite a lot of work.

Answer 7

The fiscal registrar usually stands next to the user's personal computer.
You can write a Java applet, or ActiveX, or a browser plugin. They must be able to communicate via COM or USB ports.
It is possible to write an application that will work as a web server on the user's computer and receive requests via the HTTP protocol and at the same time be able to communicate with the fiscal registrar via USB or COM.
