Attribute Set and Reset Codes
Set and reset are another way of saying turn on and turn off, select and 
deselect, or enable and disable.
Some printer features are set and reset with an escape sequence and the 
numbers 1 or 0. In such cases you can represent 1 and 0 as hexadecimal 
codes 01 and 00, or as the ASCII codes for the numerals 1 and 0 
(hexadecimal 31 and 30).
NUL Code
NUL (Hex 00) is ignored by the printer and can be used as a fill character; 
however, it can not be used to add blank spaces since it is not a space 
character. NUL can also be used as a parameter terminator for the Set 
Horizontal Tabs (page 121) or Set Vertical Tabs multibyte control code (page 
141). 
NOTE: Hex 80 in the 0437 PC Character Set and hex 7F in the 0850 PC 
Character Set are treated as a NUL; however, these two controls can 
not be used as parameter terminators.
Switching Between the Emulations
The printer supports several different emulations. PCL-II is the default. P-
Series, Proprinter III XL, and Epson FX-1050 are all a part of the LinePrinter 
Plus emulation.
The following command switches from PCL-II to Epson:
ESC%-00002X
To switch from Epson to PCL-II, send the following command to the printer:
