Abstract: The present case concerns various techniques for increasing the printing rate of an ink jet printing apparatus. As one example, drops not required for printing, that is, drop intervals, are skipped. This reduces the time required to form individual characters. Another technique modifies the normal generation of drops which is sequential in a column by column fashion and instead imposes non-sequential drop generation and deflection thereby reducing drop merging and splatter that otherwise might occur.

Abstract: An ink jet printing apparatus is described having facilities for printing information in character locations, (boxes) each character location comprising a plurality of vertical columns of drop locations, and a number of characters comprising a line of information. Structures and circuits are included for insuring correct location of information within the character boxes and also providing for one mode in which characters are printed continuously line-by-line and another mode in which characters are printed incrementally character-by-character. During incremental printing, as well as the first character in a line or group of characters, provision is made for re-bounding the printhead back into the box of the character just printed, that is, prior to the next character box to be printed to insure that when the printhead starts up again for the next character that all drop components for that character, including any located in the immediate vicinity of the character boundary, are properly placed during printing.

Abstract translation: 描述了一种喷墨打印设备，其具有用于在字符位置打印信息的设备（每个字符位置包括多个垂直列的丢弃位置）和包括一行信息的字符的数目（框）。 包括结构和电路，用于确保字符框内的信息的正确位置，并且还提供了一种模式，其中字符被逐行打印，而另一种模式则以字符逐渐打印字符。 在增量打印期间，以及一行或一组字符中的第一个字符，提供将打印头重新限定在刚刚打印的字符的框中，即在要打印的下一个字符框之前 确保当打印头再次启动时，为打印期间适当放置该字符的所有放置组件（包括位于字符边界附近的任何位置）的所有放置组件。
