LP 800  (260-2890)           IBM Control Codes         Faxback Doc. # 4121

This printer has three emulation modes:

* HP LaserJet III
* Epson FX-850
* IBM Proprinter XL24e

The LP 800 has different responses to software codes from the computer--one
set for each emulation. The response patterns, or modes, have many
similarities, but each has its own unique features.
