The system and method of this invention controls the presentation of a text document from a processing system to a printer for printing rotated and non-rotated text within the same document. The portion of text that is to be printed sideways is designated by inserting a marker at the beginning and end of the portion of the text selected for rotation. The data stream between the markers representing the selected portion of text is stored in a buffer in the processing system in one sequence, and accessed from the buffer in a different sequence. The printer prints the data stream before the marker with an internal font having normal characters. When the first marker in the data stream is sensed, the printer is sent a control to change fonts. The printer prints the data stream in a different sequence after the first marker with an internal font having either left or right rotated characters. When the second marker is sensed, the printer changes fonts and prints the data stream after the second marker with the font having normal characters.

System and method of printing sideways

An amplitude limiting amplifier followed by a filter network is interposed between the voltage amplification stage and the impedance matching stage in a Butler oscillator. This allows both the voltage amplification stage and the impedance matching stage to be operated in a linear mode at all times which assures that a piezoelectric crystal connected between the stages is connected in a relatively low, constant impedance path and is driven by a sinusoidal waveform, free of distortion, to assure maximum frequency stability.
