HP 5961-0509 Underline Command, EC & d @ Disable underline, Aligned or be the same thickness

Underline Command

The Underline command controls automatic text underlining.

EC & d # D - Enable underline

#= 0 - Fixed position

3 - Floating position

Default = 0

Range = 0, 3 (values outside range are ignored)

EC & d @ - Disable underline

Once underlining is enabled, any positive horizontal movement causes an underline to be drawn. Positive horizontal movement includes the printing of text and positive horizontal cursor motion.

When fixed position underlining is enabled, the underline is drawn five dots below the baseline and is three dots thick. (The baseline is the dot row on which all of the characters in a given line appear to stand, see Chapter 11.) When floating position underline is enabled, the underline position is determined by the greatest underline distance below the baseline of all of the fonts printed on the current line. (The underline distance for a font is defined in the font header, see Chapter 11.)

Note	The underline and the underscore character may not necessarily be
	aligned or be the same thickness.
