Abstract
A device for the transmission of information pertaining to handwriting with a piece of equipment which records the x and y-coordinates of the location of the writing pen. The device transmits the coordinates of the writing information after a suitable delay and transmits the coordinates of the commencement point of a new item of writing without delay. In this way the output receives the coordinate information of the commencement point at a time prior to the receipt of information pertaining to the writing itself, thus permitting a lower speed printing device than would be required if the output printer received the new coordinates of a handwritten item substantially simultaneously with the commencement of the coordinate information of the writing.
