Hi there!

Hey i'm working in a project, the main idea is to have a printing authentication:

1.- The user sends a job to the printer (from Word, excell, paint, etc..)
2.- before the printer starts printing, it should displayed a login box (heres my question).
3.- if the login is OK, then the print job is printed, if not, the job is cancelled.

My question is what should be done to stop the printing process to do the authentication process.

Thanks

J. Manuel

You need to create a device driver to intercept LPT port communication, use your OSīs DDK, ( WinXPDDK for winXP ).

You should look for, genprint. Basically you write a driver that captures all data sent to the printer, then, you send that data to you application and make whatever you want with it.

The only problem is DDK is very expensive so, GOOGLE GROUPS for genprint and Print Processors.

Someone here might be more helpfull...

Or after the "Ok" button is pressed, use the if statment (or something similar) and if it's true, then promt it to print.
