Abstract
A vertical tabulation control for a high speed printer comprises a presettable memory, such as a random access memory (RAM), for storing vertical tabulation addresses, a counter for counting the number of line feed operations, a comparator for developing a continuous line feed termination command when the contents of the counter reach the preset vertical tabulation address, and a rechargeable battery means which is charged when the printer is activated through a power switch. The rechargeable battery supplies the presettable memory and the counter with a necessary voltage for maintaining their contents when the power supply through the power switch is terminated.
