I am having issues printing a barcode that is legible in landscape mode. It prints fine on a desktop printer but when printing to the zebra label printer the bar code is not legible. I also installed a seagull driver per other suggestions but it still doesn’t print correctly.
Has anyone else ran into this issue and what was the fix.
Is the whole label rotated to landscape, or just the field holding the barcode?
Code39 barcodes require an asterisk at the beginning and the end of the text to be “encoded”.
*ABC-123* may render right but
might not.
And I’m fairly certain the following would not render a proper barcode:
*
A
B
C
-
1
2
3
*
the whole label is printing in landscape not just the bar code.

Did you try turning your scanner 90° ? 
I never really had a handle on what portrait and landscape mean on label printers. I can have a 4" wide printer that prints on 1" x 4" labels, and the 4" edge of the label comes out first (and is inline with the roll’s axis). On the same printer I could have 4" X 6" labels (again the 4" edge comes out first).
Does the landscape vs portrait refer to the orientations of the content of the lable, or the orientation in which it is in the printer?
I’d say the 1X4 is landscape and the 4x6 is portrait. But if the rendered labels were
and
are both landscape, no?
both are landscape

So the label is laid out to be wider than it is tall. Does your printer automatically rotate the rendered image to match the media, when necessary?
no the bar code is not printing correctly. it is all squished together. (tech term)

The whole barcode is narrower than expcted?
Or the the gaps between bars aren’t as wide? By chance is the field marked as BOLD
Other things to check would be that the field isn’t too narrow and set to compress the text
You might be onto something but if I print it in portrait there is no issues.
Appreciate all our help. It isn’t bold either
Does the width of the rendered barcode change in P vs L? Or just not making a crisp barcode image?
How about other aspects of the label? All of those are as expected?
Have you tried changing the font from Datworks to a human readable one and see if it prints as expected?
Everything looks the same on the label except the bar code is not crisp (like that). I will try human readable and see what happens. Thanks again,
One thing to consider… The printers resolution may not be the same in the two directions (one being along the feed path, and the other being perpendicular to the feed path). The pixels across the feed path are fixed, while the ones along the feed path depend upon the speed the label is moving.
Try slowing down (or speeding up) the print speed, or if there are other settings that affect the “darkness” of the printing.
According to this video “Dithering” was his problem.
