:H3.FONTPAUSE Block
:P.
A change from one font to another font often requires &WGML.
to send a control sequence to the output device.
In some cases, the font switch may require physical
intervention at the output device by the operator.

or color ribbon.

:I1.fonts
block defines a pausing method to use, and
is referenced by the device font block.
