>From earlier documentation on printer Epson JX80, it is a switch that 
controls buffer access:
ESC i1  mode: acts on each character immediately as it is sent to buffer
ESC i0  mode: does not act immediately on the character

The above might not be true for a scanner, but I expect that it will be 
very similar, and the digit following the "i" will be significant.
