ABSTRACT:
A printing device for printing on a recording paper a plurality of unit record data, each unit record data comprising a plurality of data words, in such a tabulation that the word data of each of the unit record datum are printed in respective columns so as to form a line and so as to be vertically aligned with the work data of another unit record data to be printed in the same column. The printing device comprises a data memory means for storing coded information comprised of a plurality of serially arranged unit record data, counter means for counting the number of digits of each of the word datum as the unit record data are read out from the data memory means one after another, and column width memory means for storing the number of digits of each of the word datum of any of the unit record datum which have been counted by the counter means and which define the width of the column on the recording paper. Further provided is a comparator means for comparing the number of digits in each of the word datum in any record datum which is stored in the column width memory means with that of the word datum in the next unit record datum to be printed in the same column. A column width rewriting means is provided for writing into the column width memory means, in place of the number of digits of each word datum in any unit record datum, the number of digits of the word datum in the next unit record data to be printed in the same column if the latter is found by the comparator means to be larger than the former. Printing means is further provided for printing the data in said data memory means and in accordance with the information stored in the column width memory means for printing the unit data records in columns on the recording paper.
