How to hook the printed data from windows printer and add our company logo as watermark to printout?

Hi Support

Good Morning.

I'm looking on your product if this can help us on one of our current use case.

Does the verypdf supports hooking of printed data from windows printer or print to file outputs and send data output into a virtual serial port, from which we can stream for reading and adding watermark for print commands to a special printers devices?

We will do the translation of data to known language of the end print devices. We just need to know if the software will help us read/hook data so that we can stream, read and translate it.

If yes, I would like to buy this product if you can help us on this issue we have.

Kind Regards,
Customer
