ABSTRACT:
Remotely controlled electric printer, to which each character to be printed is applied as m groups of n bits, comprising a set of n rulers or print bars, the total thickness of which is equal to the height of said character or a line thereof, each character having a width of m bits. Electromagnetic means are provided capable of shifting the print bars transversely with respect to one another, and there is a cross bridge or anvil that can be moved along said bars. Paper or some other printing carrier is provided between the cross bridge anvil and the bars. The electromagnetic means are so arranged that they can shift the rulers or bars transversely with respect to one another in accordance with the n-bit groups so that the rulers thereby strike the paper against the cross bridge anvil.
This anvil is stepped along the line in m equal steps for each character by a pawl and rack mechanism which also is operated electromagnetically by a separate electromagnetic means.
