Epson LQ-2500 Appendix E, Initialization and Default Settings

Appendix EInitialization and Default Settings

There are three ways that the printer can be initialized (returned to a fixed set of conditions).

1.The power is turned ON.

2.The printer receives an m signal at the parallel interface (pin 31 becomes LOW).

3.Software sends the ESC @ command.

These three kinds of initialization have slightly different effects. In particular, ESC @ resets the typestyle to the current SelecType settings: the other two methods reset the typestyle according to the SelecType Default Settings. These Default Settings are set only by hardware initialization and are not set by ESC @. Also, ESC @ does not initialize the printer mechanism, clear-the input data buffer, or clear the Download character set.

The following conditions are always reset:

•Present paper position becomes top of page position.

•The left margin is set to the SelecType Default Settings.

•The line spacing is set to 1/64nch.

•The vertical tab position is cleared.

•The horizontal tab position is set to every eight characters.

•The VFU channel becomes channel 0.

•The family of typestyle is set to the Selectype Default Settings.

•All special printing effects are cancelled unless they are part of the SelecType Default Settings.

•Download characters are cleared (with software initialization, they are only deselected).

•Justification becomes left justification.

•No additional character spacing is provided.
