Two-Byte HP-GL/2 Support
One-byte applications (which support non-orthogonal rotation,
scaling, and shearing of text) have long been able to use HP-GL/2 to
print to HP LaserJet printers. Two-byte applications have not had this
capability until the introduction of HP LaserJet 5 and 5M printers.
The capability of 2-byte applications (which support non-orthogonal
rotation, scaling, and shearing of text) to print to HP LaserJet printers
using HP-GL/2 is provided by the Label Mode (LM) command.
