In our latest release, you can have up to 8 Kitchen printers defined for each workstation, plus a Bar and an Expo printer. A Product can now be printed on multiple printers.
Another change is that every item that prints to a ‘kitchen printer’ is duplicated on the Expo printer, not just those Products that went to the Kitchen printer. In this sense, ‘kitchen printer’ means Kitchen and/or Aux1 – Aux7.
The Product screen allows you to select these new printing options:

This Product, at the Santa Fe Location, will print to the Kitchen, Aux2, Aux3 and the Expo printer, if one is configured.
