Make sure the serial port parameters match between the printer and the usb-serial driver. The Zebra printer is usually set to 9600 baud, 7 data bits, Even parity and 1 stop bit. The serial driver is probably different. The mismatch will prevent communications.
Hope that helps !
mmm....Ok...sorry that was not the answer. The only other thing I can think of - usually when connecting a Zebra serial port to a PC serial port, you had to use what's called a "null-modem" cable. This cable crossed over pins 2 & 3 between the Zebra and the PC. One pin is data receive and the other is data send. If a straight serial cable is used, then data receive on the Zebra is connected to data receive on the PC. Of course data receive should be connected to data send. So the null modem cable made the crossover.
I'm not familiar with the Prolific cable but maybe it's providing a "straight-through" connection instead of "null modem". I hope that rambling answer makes some sense and provides some additional info.

I checked the actual printer settings on the printer itself and they are 9600 baud, 8 data bits, none parity and 1 stop bit xon/xoff... then i checked the Prolific usb to serial port and its exactly the same as the printer... the computer recognises the printer as an unknown comm 4 port??? but its only done that since I installed the prolific driver to get the usb - serial converter working.. I'm using windows 7 by the way. when I print to Zebra driver it just says printer offline?? and I have made the port setting in that driver the comm4 and tried the usb 001 aswell... nothing seems to work?
