How to print from two printers at the same time?

Question

PHP

Hello, the problem is this:
I made a POS site, and now when an order is clogged, it is necessary to print from two printers (one in the kitchen, the second at the checkout) at the same time. And when my order is clogged, the print window pops up (CTRL + P). I have a printer for fiscal receipts.

Answer 1

And in the normal way to do poorly? ESC-POS printer protocol, RS232 connection, and write data to two printers at once - the system print window has nothing to do with it. Read the documentation and transfer data directly to the printer.
PS I used epson tm-t88v in my software - yes, you can install drivers on it and print any graphics, but ESC-POS is more reliable.

Answer 2

google the name of the console program for the OS installed on the kitchen pc, share it over the network, send the document to print using exec.
reverse option: the kitchen computer periodically (crontab) checks the folder / database for new checks, prints and deletes the entry
