c# - Zebra TLP2844 Windows 7 USB escape issue -

i on windows 7 32bit running latest drivers zebra , printing via usb tlp2844. trying generate set of labels , print them label printer c# using rawprinterhelper class mentioned in numerous posts online. if power printer , use om command disable initial esc sequence feed works , prints 2 labels correctly. thereafter height appears incorrect because instead of printing 2 labels prints 1 label second piece of text towards bottom of label. appreciated.

label dimensions: width: 75mm height: 34mm gap: 3mm

example command sequence being sent printer:

om  n q599 q272,024 zt s2        a253,26,0,3,1,1,n,"test label text" p1  n q599 q272,024 zt s2        a253,26,0,3,1,1,n,"test label2 text" p1 

as disabling detection of top of label culprit q272,024 not large enough. have not posted info not sure why using om command example not seem necessary.

try omitting q , om device should smart enough able feed correctly on it's own. (make sure have done reset make sure cleared out previous om's may have sent) make sure in line mode , not page mode.
