1. A reverse image area is affected by the rotate commands. Therefore,
always assume the printer is in the normal print orientation when
designing and sending the Reverse Image command.
2. If using reverse images with the form overlay, place this command
before the Form Overlay command in the data stream.
3. If the height and width to be reversed contain other than alphanu-
meric data, the area is not printed.
4. If the values specified exceed the maximum ranges, the reverse
image is not created.
5. See Table 1 in Section 1. Programming Concepts for values of Hmax
and Vmax.
