Sometimes it does not print 追蹤
i am using a Zebra Z4M Plus printer, Corel Draw 12, Windows 7 64Bit and the Zebra ZPL-II Driver 7.4.2 on LPT1. Mostly the printing works very well, but sometimes it just does not print. Data is sent to the printer, but only white labels are outputed. Then I restart printer or PC and somehow it works again. Can it be due to the driver settings?
