Enhancements for the Offline Switch

[RWAP]

We are now beginning to enhance the Retro-Printer software by adding more functionality to the little used "offline" switch on the top of the unit.

We have recently released a test version of the software, where the offline switch can be used in 3 modes:

a) Standard Mode - to take the unit off-line as with an old dot matrix printer
b) Emulator Mode - allows you to switch between two printer emulators as per https://www.retroprinter-support.com/vi ... .php?p=682
c) Job Control Mode - if you need to use a long timeout, this allows you to use the switch to manually mark the end of a print job

We are also considering whether this may be the best option to add another mode:
d) Tray Mode - will allow you to switch between two virtual printer trays (eg to change between A3 and A4 paper size for the next print job).
