I have spent countless weeks looking for something but am stuck and would appreciate some help.
Background:
I would like to find a small “dongle” like device that can go inline between a PC and USB printer. This “dongle” would sniff and capture the data sent to the printer and send the data via a cable or bluetooth / WIFI to a receiving PC nearby. The main point being the dongle works without requiring change on the existing hardware /software between the printing PC and the printer.
I know USB analyzers exist to do exactly what I describe, however they are costly. I need a solution that cost in $10’s as opposed to $100’s or $1000's. Devices like keyboard loggers work in exactly that way, and meet the cost criteria but as far as I know they do not work with printers.
Anyone has such a product or is capable of designing something like?
