Configuring the PCL-II Emulation with Control Codes
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:
ESC&l1L
ESC&l0L
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.
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.
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.
Print Mode Selection
The standard, compressed, and double-high/double-wide print modes are
selected using the ESC&k[0,2,4,8]S sequence as shown in the following
table. This escape sequence affects both the primary and secondary
character fonts. The default print mode is that of the default font specified
from the control panel. Only one print mode is allowed per line.
