Tips and Tricks for Smart Forms and Zebra
Printers
Smart Forms was originally developed for “Form” and “Report” design, not labels. Smart
Forms can now be successfully used to design labels on high performance bar code label
printers, but you need to be aware of the tips and tricks not documented within the
original Smart Forms manuals. Please read the following:
Label Size / Page Size
In Smart Forms, a page format must be set for every form or label, for example, DINA4
or LETTER. For the Zebra printer driver it does not matter which format is set here, since
it cannot affect the label size in the printer. It is therefore of no benefit to define separate
new page formats/format types for labels for label printing with the above zebra device
types (just use DINA4 or LETTER). However, in Smart Forms, when you define the
window on the page, ensure that you only use the label area that is actually available.
Important Note: in Smart Forms, only use the PORTRAIT page orientation. It is not
possible to rotate the orientation of the label by 90 degrees by selecting the
LANDSCAPE page orientation. Technical background: In the ZPL II printer language,
there is no command for rotating the output of the entire label by 90 degrees. The printer
driver therefore cannot use orientation=LANDSCAPE to rotate the label by 90 degrees.
If you need to shift the entire label output slightly on the Zebra printer, you can use the
form output shift in the SPAD transaction (when you define the output device), as
described in note 39259. This shift is analyzed by the Zebra driver.
Smart Forms has no concept of Label Size. Please ensure that the Main Window is larger
than the label.
Workaround for rotating the label output: There is a command in the ZPL-II printer
control language that rotates each individual field by 90 degrees (clockwise). If you insert
this command into the output data stream using the “command nodes” mechanism as
described below under “Printer Settings”, you will achieve the rotation of individual
fields at printout. However, you must adjust the position of the fields (or windows) in the
form to obtain a "landscape" printout, as Smart Forms and the printer driver are
not aware of the rotation. Therefore, define the Smart Form with the "portrait"
orientation. For the rotation, add a command node, for example in the MAIN window. In
this command node, enter the following under "spool control", "free
attributes":
Attribute name: Attribute value:
S_LZPL_SETUP '^FWR'
The LZPL printer driver sends the ^FWR command to the printer at the beginning of the
label and causes a rotation of the output fields.
