When "mode setting" is initiated in a serial printer, various options for a previously selected printer mode (e.g. paper size, print resolution, emulation, etc.) are sequentially printed on the print-receiving member (e.g. a sheet of paper) in the lateral direction, i.e., a direction parallel to the direction in which the printhead is scanned to record image information. By selectively moving the printhead carriage to a position in which a reference mark thereon, such as an arrow, points to a desired option printed on the print paper and sensing the displacement of the printhead carriage from a home position, the desired option can be selected and caused to replace the currently set option for that printer mode. A particular printer mode can be selected in the same manner, that is, using the printhead carriage as a "pointer" to select a desired print mode from a lateral display of available printer modes which have been printed on the print paper. Such a scheme avoids the need for DIP switches and/or liquid crystal displays for mode-setting. Mode setting is easy, requiring only software. |
