Zebra RW 420 not printing last or first inch using ZPL

Question

Zebra RW 420 not printing last or first inch(depending on rotation) using ZPL.

this link was suppose to give a solution since it is the same symptom; but I've try all combinations of "Back Feed" (~JSN, ~JSA, ~JSB) with no results.

here is my ZPL code(generated from ZebraDesigner print to file command) It doesn't print "Hello 22" completely:

^XA~TA000~JSN^LT0^MNM^MTT^POI^PMN^LH0,0^JMA^PR2,2~SD10^JUS^LRN^CI0^XZ
^XA
^MMT
^PW812
^LL2233
^LS0

^FO272,76^A0N,56,55^FH\^FDHello 11^FS
^FO320,2000^A0N,56,55^FH\^FDHello 22^FS

^PQ1,0,1,Y^XZ

Answer 1

I've solved the problem with the help of Zebra support.

The actual problem was the var "zpl.label_length" that was set to 2014 instead of 2233; the ^LL command is ignored in this printer and the label length is controlled only by "zpl.label_length". It printed the whole label(11")after sending the command:

! U1 setvar "zpl.label_length" "2233"

Answer 2

I had the same problems with print output. I ended up abandoning use of ^FO and went with ^FT, and everything has been perfect since. I don't know why ^FO is so temperamental, but ^FT is very straightforward. You get what you expect.

I'd suggest getting rid of that entire first row that ZebraDesigner made. You don't need it.
