Abstract:
1. An electronic method for printing, the method comprising: determining that an indicator has been preset for switching from a simplex printing mode in which only simplex printing is permitted to a duplex printing mode in which simplex and duplex printing is permitted, wherein detection of the indicator in received print data causes duplex printing to occur while in the duplex printing mode and wherein absence of the indicator in received print data causes simplex printing to occur while in the duplex mode; initializing the duplex printing mode instead of the simplex printing mode based on determining that the indicator has been preset; receiving print data from a host computer, the print data including the indicator, wherein the print data does not include supplemental duplex or simplex printing settings; writing a first portion of the print data to a first memory unit until the indicator is detected within the print data; writing a second portion of the print data following the indicator to a second memory unit; printing a first side of a paper according to the first portion of the print data; and printing a second side of the paper according to the second portion of the print data, wherein the indicator comprises at least one predetermined character that is printed on the paper.
