Chapter 2 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).

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.

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.

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

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.

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.
