Hello Naomi

Thanks in advance for your reply, and also the replies for all the members, but i still have the same problem, i will try to explain all:

1- my printer is TM-T88II, serial and connect to my pc with a cable 25 pins to 9 pins (Serial).
2- My casdrawer is connect to this printer through RJ11 cable.
3- My OS is Vista SP1
4- I have install "Epson Advanced Printer Driver" Version 3.06E, not the EPSON OPOS program

Your code that you have send to me, when running make the printer print a short paper and cut them, but they don´t open my casdrawer.

I don´t know in the moment how can resolve this situation, because your sequence code is the Epson sequence, also if i try sending the letter "A" using the special espon font, nothing happens.

I also type on command line : mode LPT1=COM1
and after this, i type : DIR >LPT1 , and the printer print OK.

I will try also mapping a virtual port with : NET USE LPT1: \\127.0.0.1\EPSONTM "EPSONTM" is the Shared name assing to the printer.

I don´t know if i make a big confusion , because this is the first time that is occurs.

Could you try to help me again, I would be very grateful.

Many thanks
Luis Santos
