PCL 5

If the document is printed as duplex (refer to the “PCL Duplex
command” section), the behavior differences between the HP
LaserJet 4si and the DocuPrint are greater. The simplex issue in
which DocuPrint copies are collated and HP LaserJet 4si copies
are uncollated also applies to duplex printing. Additionally, the
DocuPrint will blank the back side of the sheet and pull a new
sheet if the copy command occurs on what is normally the back
side of a sheet. However, the HP LaserJet 4si does not pull a
new sheet of paper when the copy command appears on the
back side of a sheet. Instead, the HP LaserJet 4si will place
multiple copies of both the front and back sides of that sheet into
the output, even though multiple copies are not requested for the
front side.
The following is an example of the same job as shown above,
printed as duplex:
