Hi guys,

I have to develop an application to capture the "printed"
data from another machine.

I have a specialized hardware (not a computer) that has
only a parallel port (Centronics-SPP) connected to a
printer. I think the only way to capture the information
that the system send to printer is connecting a computer
to this parallel port and pretend to be a printer. So, the
system will send the information and I could filter the
data.

I have no idea how to do it!! I found a lot of information
about parallel ports, but nothing related to my doubt. If
someone could help me, I really appreciate.

Thanks.

Hello, Carlos:

I don't know if this can help, but...:
You may find in the Internet a driver for that job or write it yourself.
Another way might be to buy a hardware conversor Parallel <=> Serial and use the well known MSCOMM32.OCX to perform the communication.

Regards.

Hello, Carlos:

See a list of DLL and controls in the page http://www.lvr.com/parport.htm at the section "Programming Tools for Port I/O and Interrupts ".

You need a tool like those. In fact I didn't give you the link on the other post because I thought this tools do not meet your expectatives... I should have given you the chance of deciding... Read the information of the links to see if any of the tools adjusts to your requirements. You may find more tools searching the Internet for something like "Visual Basic Parallel I/O"...

Forgive me for giving too little intormation to you... :-(

Regards.

Dear José,

I looked for a driver like you told over the Internet and
I couldn´t find it until now. I´ve looking for a week. So,
if you could help me telling where I could find it,I´ll be
very glad.

About the conversor, I think it is a good idea, but I am
trying to solve this problem only by software. If it were
not possible, or if it were not easy, I´ll considerate
this idea.

Thank you very much for your consideration.
