Setting the Page Length

The following considerations should be observed when you set the page length.
•In the default case any form or page length sent from an emulation (the
^L or ^H command in VGL and the length defined within the ~CREATE
statement in PGL) will be used to force the page length.
•The label gap sensor does
not
measure the label length and, instead,
continues to use the page length from the secondary control panel or a
HOST FORM LENGTH value. Therefore, you
must
set the form length
properly, either through the secondary control panel or through the host,
even if the gap sensor is enabled.
Note that when the gap sensor is used, it will still control physical paper motion; it
does not just control the logical form length that the printer is using. Therefore, if
the page length you have selected (either from the secondary control panel or
through the host) does not match the physical page length, then the printer will
attempt to map the logical page onto the physical page.
If the user-selected page length is shorter than the physical page size, the printer
will leave white space at the end of the label so that the next logical page will
start at the beginning of the next physical page. If the user-selected page length
is greater than the physical page length, the printer will clip the page to fit onto
the physical page.
The following recommendations indicate how best to set up the printer and use
the gap sensor.
•If the application sends the form length to the host, then there is
probably nothing to change in the setup (other than to enable the proper
gap sensor). The printer will use it for the logical form length, and the
application will also be using it. As long as the label length is really the
same as the form length (which it should be), the printer will operate
normally.
•If the application sends the form length to the printer but it is inaccurate
(e.g., you wish to fit two logical forms onto one physical page), then you
must
change HOST FORM LENGTH to DISABLED and must also set
the page length in the secondary control panel to the physical label
length.
•If the application does
not
send the form length to the printer, then you
must
select the form length from the secondary control panel. This value
must be accurate, both in terms of what the application expects and the
physical page length. If it does not match the physical page length, then
there will be clipping or extra white space.
