Epson 4100 Printer User Manual


 
288 DEC LA210 Control Commands
Two groups of control codes may be active in the printer: C0 (decimal
range 000 to 031) and C1 (decimal range 128 to 159).
Control codes in C0 are always active. Control codes in C1 are enabled if
upper data bytes have been enabled by selecting "8 Bit DEC" in the
configuration menu and if control command ESC SP 7 has been received.
Otherwise, the printer sets the MSB of data bytes received in the decimal
range 128 to 159 to 0, effectively mapping them to C0, decimal range 000
to 031.
The position of the control codes is shown in these maps.
