The basic difference between the Simulator and Emulator is, Simulator runs on Desktop environment and totally Software related. Whatever u test on Device , u can do in simulator also, but this is n0t 100% sure.
Emulator is both Software and Hardware, here u can test the device 100%.
In Printer device simulator does not support the Physical interface, ex removing the cartridges. Also in emulator we can perform the physical interface related testcases.
