Configuring the PCL-II Emulation with Control Codes
Before changing the page length, it is recommended that a VFC select of
channel 0 be performed. This will bring the printer to the top of the next
physical page (unless the printer is already at the top of the physical page).
channel 0 be performed. This will bring the printer to the top of the next
physical page (unless the printer is already at the top of the physical page).
Changing the logical page length changes the standard VFC table.
Text Length (Vertical Margin) Selection
(PCL Level II)
The length of a form within a logical page is set using the ESC&l[1-128]F
sequence, where the number of lines desired (1-128) is specified. The first
line of text is printed at the Top of Form position. The physical page length
minus the text length defines the total vertical margin (top plus bottom margin)
for the page.

line of text is printed at the Top of Form position. The physical page length
minus the text length defines the total vertical margin (top plus bottom margin)
for the page.
If a text length of zero is received, the text length defaults to one inch less
than the logical page length. The default text length, which is invoked any time
the logical page length is changed, is one inch less than the logical page
length. If the logical page length is one inch or less, the text length is set equal
to the logical page length.

the logical page length is changed, is one inch less than the logical page
length. If the logical page length is one inch or less, the text length is set equal
to the logical page length.
Perforation Skip Mode
(PCL Level I)
When perforation skip is enabled, the printer skips to the next Top of Form if
the bottom margin is entered following a line feed. The following escape
sequences enable and disable the perforation skip mode:

sequences enable and disable the perforation skip mode:
ESC&l1L
Enable perforation skip mode
ESC&l0L
Disable perforation skip mode
If a programmable VFC is enabled, the end of text is determined by the first
occurrence of channel 2. If channel 2 is completely clear, the end of text is the
end of the page (that is, there is no perforation region). The text length
defaults to one inch less than the logical page length unless the text length
has been specified with the ESC&l[1-128]F sequence.

end of the page (that is, there is no perforation region). The text length
defaults to one inch less than the logical page length unless the text length
has been specified with the ESC&l[1-128]F sequence.
Perforation skip mode defaults as configured from the control panel.
When the perforation skip mode is disabled, the printer will print in the margin
space below the desired bottom of text. This can be avoided if a VFC select to
the next Top of Form is performed immediately following the last desired line
of text on the page.

the next Top of Form is performed immediately following the last desired line
of text on the page.
NOTE: Many systems perform an automatic page eject which overrides the
printer’s perforation skip mode. If the user desires to print in the
perforation skip region, the system’s automatic page eject must be
disabled.
