Zebra TLP 2742 printer only prints out lef...

I have a Zebra TLP 2742 tag printer, it was working fine with my old computer Since I have transfer all the info. to the new Business pc the printer won't work. I have installed the software through internet and played around with it before installing the printer with the new pc. Now when I send the job to printer its only prints out blank tag or sometimes its only prints out left side of the tag. I have tried reinstalling the driver and the printer, also resetting the print putting in Dump mode but no solution... I’m afraid if I changed some setting by mistake on the software/driver …Please help!!!
