Adobe PCL4 Emulation

The Adobe emulation of the Printer Control Language (PCL4) on the DEClaser
1152 printer differs from the Hewlett-Packard implementation, in the following
ways:

•

The Line Printer font does not exist, and uses the Courier font instead.
Both fonts are fixed-pitch fonts and only minor differences will appear in
the document.

•

The printable area for some page sizes may be slightly larger or smaller
than those on a HP LaserJet IIP printer.
