Abstract
A device for limiting the number of printing columns in a printer in which a group of printing data codes transferred from a data source are successively compared with a group of type codes which are determined in correspondence to the instantaneous positions of type on a type carrier, so that a type in a place where a printing data code coincides with a type code is printed. The device comprises a reversible counter adapted to subject a coincidence signal relating to said printing data code and type code and a printing completion signal for each place to addition and subtraction, respectively, so that when the count value of the reversible counter reaches a predetermined value, printing for further places is inhibited.
