(User's Guide ML395/ML395C)
Epson LQ Commands
Note Normally the commands in this table override Menu settings. Except as noted, these commands are cancelled and the printer returns to the factory and Menu settings when the printer receives an Initialization, Software I-Prime, or Change Emulation command, or when it is turned off.

This section contains the commands for the Epson LQ emulation, grouped by function.
