ZPL Basics
The ZPL Format (Receipt Form or Template)
10/29/2010 Software Integrator Guide P1026208-001 Rev. B
Placing Objects in the Image Map
Objects get placed into the image map by a few simple methods.
Recall Format (
^XF) and Image Load (^IL) place objects directly into the image
map without referencing location within the image map.
The Field Origin (
^FO) command is used to place objects in the image map and
start the ‘field definition’. It references object placement from the top left corner of
the object. The object is then described (e.g. font, size, rotation, type of object,
etc.). Text and bar code data are then added. The Field Separator (
^FS) denoted
the end of the field definition and the objects placement in the image map.
The Field Origin (
^FO) command only allows the placement of a single object
in the ‘field’.
The Field Typeset (
^FT) command is used to place objects in the image map in a
similar method to the Field Origin (
^FO) command. It places objects into the
image map by referencing to a text object’s baseline (Figure 8-3 on page 120) or
the bottom of a bar code or graphics object. The Field Typeset (
^FT) command
has a justification parameter that determines which side (left -the default or right)
determines object placement. The Field Separator (
^FS) denoted the end of the
field definition and the objects placement in the image map.
The Field Typeset (
^FT) command supports multiple text objects with
limitations. See the Field Typeset (
^FT) command in the ZPL Programmers
Guide for your kiosk printer.
See the Field Interactions section of the ZPL Programmers Guide for your kiosk
printer for illustrated examples of the
^FO and ^FT and their interactions with text
formatting and various justification parameters.
Inputting Various Data into ZPL Code and the Printer
ZPL is capable of importing a variety of data into the ZPL command structure. Each
command that uses externally provided data has rules outlined in the ZPL Programmers
guide for importing text data strings for use with fonts and bitmap graphics.
Text data supports ASCII, hexadecimal encoding, Unicode, Unicode character
encoding, XML, common 7 and 8 bit code page keyboard mappings, and some
ASCII control characters. Note: A font, a group of linked fonts, or a custom font
mapping capable of displaying the text must also be applied to the text data.
Importing logo graphic files is typically supported by inclusion of binary data or
binary converted to a simple ASCII encoding scheme. Graphic files (binary) can
be merged with ZPL code (ASCII) or sent as separate files. See the
^DY
command in the ZPL Programmers guide.
Font file import directly supports importing font files (TrueType and OpenType) by
merging the file with ZPL encoding (ASCII) or sent as separate files.
