Thank you for your answer
If it is not a network printer do you want to user two printers or just one printer and two printouts 1) invoice and 2) order items?

Is your order printer a network printer (say kitchen printer)? In that case you would need a PoSbox/raspberry pi device?

=> If you mean Wifi/ethernet interface printer, those don't have.
=> I'm thinking that the POSbox+USB printer works as a Network printer, isn't it ?
> For now I managed to do a test with 2 printers USB connected on the same POSbox. IP of the POSBox is declared
- in the POSbox IP address
- in order printer.
=> It prints both orders and invoices with the same printer.
=> I want to know if I have another POSbox, I'll be able to simply declare the IP address of the second POSbox (connected with my USB Printer) in "Order printer".
