4-8 PCL Job Control Commands EN
Top Offset Registration Command
The Top (short-edge) Offset Registration command designates the
position of the logical page along the length (long side) of the physical
page.
? & l # Z
# = The number of decipoints (1/720 inch)
Default = 0
Range = –32767 to 32767
The value (#) is a signed number valid to 2 decimal places. The units
are decipoints. Positive values cause the logical page, regardless of
orientation, to move down along the length of the physical page,
except on the backside of sheets printed in short-edge binding duplex
mode, where positive values cause it to move up (refer to Figure 4-4
and Figure 4-5).
Negative values cause the logical page, regardless of orientation,
to move up, along the length of the physical page, except on the
backside of sheets printed in short-edge binding duplex mode, where
negative values cause it to move down (refer to Figure 4-4 and
Figure 4-5).
Notes The +/– value is absolute with respect to the default position of the
logical page along the length of the physical page. It is not relative to
the current location of the logical page.
The registration command may cause data loss by moving the logical
page outside the printable area.
This command has the same effect regardless of orientation.
This command can be used in both simplex and duplex modes.
