The current print position becomes the next printable column at the newcharacter-per-inch setting. CPI can be changed within a print line, and this controlchanges the maximum number of characters that can be printed on one line.A combination of 10 CPI and Condensed Print sets the printer to 17.1 CPIregardless of the 20 CPI setting in the Power On Configuration menu.A combination of 12 CPI and Condensed Print sets the printer to 20 CPI when20 CPI=YES is set in the Power On Configuration Menu. A combination of 12 CPIand Condensed Print sets the printer to 12 CPI when 20 CPI=NO is set in the PowerOn Configuration menu.Device Control 1 (DC1) / Select or XON11This control has different meanings depending upon the currently active interface.v Parallel interface (Select): DC1 selects the printer.v Serial interface (XON): DC1 is treated as a NUL if received from the host.
