Zebra ZPL label printers carry over the print commands from print job to print job. So if you send a ^FWR command that rotates a label, all future jobs will be rotated, so you have to reset the orientation to ^FWN if you want to have the next label be printed in portrait mode.
Is there a way to automatically reset the 'standard' settings on a Zebra on each print job? So settings from the previous job don't carry over to the next job? I want every zpl file I send to the printer to be printed exactly the same, regardless of what was printed prior.
Or is there a default set of commands that I can send that reset the orientation, fonts, position, dpi, measurements, etc?
There's a command that does a power-on/factory reset, but I don't want to do that on every label print.
You can manually reset all unwanted settings.
This works for me
^PON^LH0,0^FWN
.
FWN resets field orientation
LH resets the offset
PO resets print orientation
Not sure if all of those are needed and/or others would be needed for you too. In my particular case, I did not need FWN.
My printing got messed up when pasting some sample ZPL to the printer. Next 30 labels had orientation and offset changed making them unusable. So I just have above command in beginning of my labels now.
You might specifically have to reset other settings too.
