counts. 2. Clears all printer receive buffers and formatting
buffer. 3. Resets printer indicators to cause skip to old line on a
start condition. 4. Resets the current print position to 1 (the left

and parameter error indications in the printer. 7. Causes certain
printer unit errors to be reported again even if they had or had
not been reported. 8. Prints the residual buffered data.
