Abstract: A tape printing system includes a control apparatus and a tape printer, wherein the control apparatus includes an image data generating section generating character strings and/or image data, and an image data transmitting section transmitting the generated character strings and/or image data to the tape printer, and the tape printer includes a processing pattern storing section storing a processing pattern for each tape type, the processing pattern of processing the character strings and/or image data to printing image data, a tape type determining section determining the tape type of a printing tape, an image data receiving section receiving the character strings and/or image data from the data transmitting section, a printing image data generating section generating printing image data by processing the received character strings and/or image data based on the processing pattern, and a tape printing section printing the generated printing image data on the printing tape.

Abstract: Printing which accommodates carriage speed non-uniformities by allowing both forward and reverse printing despite the presence of ringing and other overshoot anomalies in carriage printing speed. A determination is made as to whether print data for a current scan and a prior scan overlap in either of two critical zones at lateral extents of the recording medium, where carriage speed ringing and overshoot non-uniformities are most prevalent. If print data for a current scan and a prior scan overlap in either of the two critical zones, the current scan is printed in the same direction as that of the prior scan. On the other hand, if print data for the current scan and the prior scan do not overlap in either of the two critical zones, then printing of the current scan is effected in a direction opposite to that of the prior scan.

Abstract: In an information processing apparatus with a main control unit and a printer, a transfer unit transfers commands and data between the main control unit and the printer, a memory temporarily stores the data transferred to the printer, and a detector detects the remaining capacity of the memory. The information on remaining capacity of the memory is supplied to the main control unit to improve the execution efficiency of the main control unit.

Abstract: There is provided a printer comprises a first type group having a first font; a second type group having a second font; a first read only memory in which a space traveling amount corresponding to each type of the first type group has been stored; a second read only memory in which a space traveling amount corresponding to each type of the second type group has been stored; and a microprocessor which selects the 1st read only memory when the 1st type group is used, thereby allowing the propotional spacing operation corresponding to each type of the 1st type group to be performed, and which selects the 2nd read only memory when the 2nd type group is used, thereby allowing the proportional spacing operation corresponding to each type of the 2nd type group to be performed. Since the invention can be constituted by a simple hardware, by merely adding this hardware to a conventional printer such as an electronic typewriter, the fine proportional spacing can be executed for each type of various kinds of fonts.

Abstract: A tape printer automatically expands an input character string up to the length of a desired printing range. Operating a fixed length key after input of printing data causes an indication, for example, "PRINTING LENGTH: 10" to appear. The "PRINTING LENGTH" indication is varied by, for example, rotating a character selecting dial. When a printing key is operated, an actually printable dot column count is determined from the selected printing length. The dot column count minus the total character width (dot column count required to print all desired characters) provides a margin space YS. If the margin space is equal to or greater than the total character spacing (i.e., the number of inter-character positions), a new margin space YS is determined, and the character spacing value is incremented by one dot column. The characters are then printed on the printing tape using the spacing value thus obtained.
