Text, bar code and image fi elds also require some input data:
• Text Field:
• Bar Code Field:
• Image Field:
The input data to text and bar code fi elds may either be provided
by the host or read from the printer's fi rmware, for example coun-
ter values or various data related to the printer's clock/calendar.
In Intermec Direct Protocol, you can either specify the fi elds
both with regard to formatting parameters and input data in the
same string, or you can create a layout to which you can send
variable data later.
The layout should contain formatting parameters for all fi elds
and input data to such fi elds that will always contain the same
information. When the variable input data are added, they will
be inserted into their respective fi elds (like fi lling in a pre-printed
form).
When creating predefi ned layouts, special commands must be
used for:
• Starting the layout recorder
• Saving the layout
Depending on the type of fi eld and the type of bar code, print-
able data to text and bar code fi elds may consist of:
• Alphanumeric data (text)
• Numeric data
• Counter values
• Current date
• Current time
• Current date +/- nn days
• Current time +/- nn seconds
• Current week number
• Current weekday
