Appendix E Initialization 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: l Present paper position becomes top of page position. l The left margin is set to the SelecType Default Settings. l The line spacing is set to 1/64nch. l The vertical tab position is cleared. l The horizontal tab position is set to every eight characters. l The VFU channel becomes channel 0. l The family of typestyle is set to the Selectype Default Settings. l All special printing effects are cancelled unless they are part of the SelecType Default Settings. l Download characters are cleared (with software initialization, they are only deselected). l Justification becomes left justification. l No additional character spacing is provided.
