Using Special Type Effects
The printer can create special type effects, such as patterns, reverse
printing, mirrored text, and font rotation. See the user guide for your
application to verify that the application supports these features.
Developers can find complete instructions for using special type
effects in the
PCL Technical Reference Package, which is available
through HP Direct.
