Abstract

PURPOSE:To simultaneously execute the printing by justification over a plurality of lines by determining a space for printing by justification at the final words from a printing zone set in format from the final characters of input lines. CONSTITUTION:Width and space distance of a character input by input means 1 are sequentially integrated, and output to final space distance calculating means 5. Character memory means 3 sequentially stores character code, space code, return code input from the means 1 at a line unit. Final space detector 4 provides justification printing candidates from printing information stored in the means 3. For example, it detects the final space code input immediately before a word and outputs its printing space distance to the means 5. The means 5 calculates justification space distance corresponding to the final space code stored in the means 2 by referring to the integrated amount output from character width accumulating means 2, printing space distance, format, etc., corresponding to the the final space code, and outputs to printing means 6.
