Figure 3 is an example of the output from this DPL command
stream. The user has the ability to change the point and set size of
the font within the DPL command record. In addition, the angle of
the baseline may be specified relative to the current orientation of
the record. (For example, the command \<FR+45> will rotate the
baseline forty five degrees in the positive direction from the
default print direction.)
Note: Refer to Section 8 for more information regarding the DPL
record format for a scalable font text string.
