PROGRAMMING THE DISPLAY OPTION
Introduction:
QL and RW series printers with the LCD control panel option use the WML language to create screens
or “cards” for the display. This section explains the WML tags and commands used to create a menu for
the LCD. The file should be named INDEX.WML. This file can be sent to the printer via an FTP session or
by using Label Vista. By using a line like $(vnd.zo.parameter name) you can display the value of that
parameter name as seen in example 1. Refer to Section 14 of this manual for complete information on
available parameters.
Refer to Table 1 at the end of this section for information on WML tags used by the QL and RW series
display.
The first card to be displayed should always be called “main”. The following example demonstrates
the timer function and uses this to refresh the LCD to give a current battery voltage, head latch status, and
paper out status. In the example each line is followed by a CR/LF (0x0D/0x0A).
Example 1:
This is a complete menu that demonstrates most of the tags from Table 1 at the end of this section. The
<do> tag is shown is Example 2.
