Hi, does anyone control the Zebra printer by using nsbasic? I am using the the \
nsbasic to testing the Eltron TLP2742 printer by RS232 serial port but it cann't \
work. The codes are:
Dim outStr as String
Dim err as Integer
outStr="Hello"
err=serialset("PortID",1)
err=serialopen(0,9600)
err=serialsend(outStr,len(outStr))
MsgBox str(err)
It returns "770". However, I test the printer through its driver, it can print out \
the test page by com 1. If not use the serialsend function in the above codes, just \
open it, it returns "0". I have checked the setting of the printer, it is: Baud \
rate--9600, parity--None, data lenth--8, stop bit--1. Could any one give me a \
suggestion about the issue? Thanks!
Aaron
