The present method permits all spaces, tabs, graphics and backspaces to be underscored between a Begin and End Underscore without requiring an extra pass or scan of the line. Using this method, additional process time and print memory space required for underscoring can be reduced. The present method requires that the data be processed as it is received and then placed in a buffer for output to the printer. As the data is received, the horizontal position of the character is tracked. When a Begin Underscore and an End Underscore are received, four special words are stored in the buffer for output to the printer.
