Is it compatible with all escpos printers?

[krishnatheog]

I want to know if this package is compatible with Datamax o'neil printers ? Is there any way to check the output without a physical printer. Maybe like a simulation or something? Should we go inside the app and then connect to the printer or will this work if the printer was already connected to the device even before entering the app ? It would be really helpful if someone could answer these questions. Thanks in advance.
