1.Call the printer via SDK

iMin SDK provides packaged common printing instructions, so that developers can quickly access iMin printers

Print Demo source code

1、Printer initialization

Function：initPrinter()

Remarks：Reset the printer’s logic program (for example: layout settings, bold and other style settings), but do not clear the buffer data, so unfinished print jobs will continue after reset.
