Several POS device connected to the same printer problem

[Edy]

I do the restaurant business

I got 6 kitchen printer, and 4 POS device (Android Tablet). All is Ethernet printer, connected by LAN cable

One employee will use one device, to key in the order. Then all order will print-out to all 6 printer.

All 4 employee do the same thing.

The issue is, sometime the device will suddently show the printer connection error randomly.

We have checked to all hardware, but all is fine.

Hello @Edy

It can happen when your local network becomes busy.
I recommend getting the latest Wi-Fi router and not sharing the Wi-Fi network with your customers.

You can also try rebooting the Wi-Fi router.
