Hi, i have a Point of sale program that use a epson tmu200 printer. also it usea a cash drawer. the cash drawer is connected to the printer epson by a rj11 cable, the pirnter epson send a pulse and open the cash drawer. the printer epson is a paraler port
i use this code
Open "LPT1:" & strcommNumber For Output As #1
Print #1, Chr(27) + Chr(112) + Chr(0)
if i use a serial , or a usb port printer, it don,t open the cash drawer, the code is just for pararel port printers.
The question is some body know the code to open tha cash drawer with a usb port printer ?
