Blank label after printed label ZQ 320

Hi,

I'm implementing a software that prints black marks labels with Zebra ZQ320. With pattern of the label everything is OK. I have difficulties with calibration. Because it prints all time a black label after.

So, Here my configurations:

I've found here commands for printer's calibration:

^XA

^MNM

^XZ

~JC

^XA

^JUS

^XZ

Then, I'm trying to print my label:

^XA

^PON    (print orientation)

^MNM    (specify media type, M - mark)

^XZ

^XA

^FO0,35^GB560,300,2^FS

^FO150,100^ADN,18,10^FD TEST TEST TEST

^FS

^XZ

Also, I configured language to ZPL and media handling to TEAR OFF

! U1 setvar "device.languages" "zpl"

! U1 setvar "media.printmode" "tear off"

Issue here, that after printed label I have all time a blank label and I can't find a solution how to print label without blank labels. What am I doing wrong?

I seems, that printer didn't see length of the label. It's 2 inches. But ~LL doesn't work with non-continuous mode..

And here information about "media" and length of a label:

! U1 setvar "zpl.label_length"  gets "404"

! U1 getvar "media":

media.status : ok

media.sense_mode : bar , Choices: bar,gap

media.tof : 0 , Choices: -400.0-400.0
