Abstract: A recording control arrangement for a dot recording machine, having a recing medium and a recording member for recording dots on the medium which is movable relative to the recording member. The control arrangement includes at least one storage member having a plurality of storage locations each adapted to contain a data bit required to cause a dot to be recorded on the medium. A data bit generator for generating data bits which are connected to the storage member to allow them, when actuating, to transmit to the member a bit combination belonging either to a first set of bit combinations, each of which causes an image forming part of a first series of given images to be formed on the medium, or to a second set of bit combinations each of which causes an image forming part of a second series of given images to be formed on the medium, each of the images in the said second series being identical to a respective one of the images in the first series, but being rotated through 90.degree.
