I don't know who you talked to, but don't despair.  PCL does not have
a specific reverse line feed sequence, but the absolute cursor move sequence
can be used to place the cursor anywhere on the page and the relative
cursor move sequence can be used with negative values. Send an:

Esc&a-1R

to move the cursor up one row.  Hence this is equivalent to a reverse
line feed.  Sorry someone gave you the wrong data.  The LaserJet
printers are page oriented devices so of course you can randomly move
the cursor anywhere you want on the page anytime you want to.
The above sequence is called "vertical cursor positioning by rows".
