Media

IMPORTANT
All distances under Media can be represented in inches or millimeters based on
the menu System > Control > Media Units.

Intro: Label Length

Understanding your media and application is very important when configuring the parameters in the menu
system. When setting label length, consider the following:
Label Length can be manually entered via the control panel Media > Image > Label Length menu or sent
via the host application (e.g., PGL job) using the appropriate software command. If sent via a software
command, that is referred to as a Host Forms Length or Logical Label Length.
A Host Forms Length (Label Length) value sent from the host computer can override Media > Image >
Label Length value if the emulation chooses to do so. Often, the emulations will have a menu to configure
that behavior (e.g., Application > PGL Setup > Host Form Length).
Physical Label Length is the actual measurable length of the label. The following list of different media
types explains how the physical label lengths are determined:
•
Die-cut labels – measurable length of the removable label (leading edge to trailing edge). This does not
include the liner material or gap.
•
Tag Stock with notches or holes – measurable length from the trailing edge of one notch or hole to the
leading edge of the next notch or hole.
•
Tag Stock with black marks on underside – measurable length from the leading edge of one black
mark to the leading edge of the next black mark.
•
Continuous media (no label length indicators) – measurable length should be within ± 1-2% the Label
Length value entered in the Media > Image > Label Length menu or the value sent via host software
command.
Logical Label Length (or Host Forms Length) is the length that a user or programmer bases his
printable image on. In most cases this length should be slightly less than the Physical Label Length. This
allows the entire image to be printed within the boundaries of the label length indicators (gaps, notches,
holes, or black marks).
When the Logical Label Length is greater than the Physical Label Length and Media > Image > Clip Page is
"Enable", the printer will clip the bottom portion of the image that exceeds the Physical Label length. In this
case, the printable data that was not printed will be lost. There is more on Clip Page menu in the next
section.

Intro: Clip Page

The media sensor looks for the gap, notch, hole, or black mark only after the media has advanced the
distance specified by the Media > Image > Label Length menu or by the Host Forms Length coming from
the application. Any gaps, notches, holes, or black marks that exist prior to reaching the Label Length or
Host Forms Length value are ignored.
When Media > Image > Clip Page is "Disable", Mark and Gap media sensing reliability can be improved
and the sensor problems described below can be fixed:
•
The image starts to print at an erroneous distance from the top-of- form, especially towards the
end of a roll where the media is severely curled or scalloped.
•
The image is incorrectly positioned as a result of the media sensor triggering off of a dark,
pre-printed image on the label or multiple gaps within the label.
•
The printer starts to print one label and then another all on the same physical label, especially at
the end of a roll where the media is severely curled.
