Enables the automatic underline enhancement.

!

This command must use a capital “D” as a terminator.

Except when changing the left margin causes positive horizontal CAP movement, when underlining is enabled, each printed character or any positive horizontal motion (e.g., spaces, CAP moves) is automatically underlined.

Once enabled, underline remains enabled until explicitly disabled. The default state is under- line disabled.

A single underline is produced if double underline is invoked but unavailable, as in the case of the DeskJet 850/870/890 Series printers.

When fixed location underlining is enabled, the underline is drawn a fixed, device-dependent distance below the baseline. When floating location underlining is enabled, the greatest under- line distance specified in all of the fonts printed on the current line determines where the underline is positioned. The underline distance and height is defined in the font descriptor.

In the HP DeskJet implementation of “floating” underline, each font defines the thickness of the underline character and its position relative to the baseline.
