I am trying to intercept raw print data stream from a POS system, modify it
before sending it to a networked Epson thermal receipt printer as described
below:
i) Intercept print data,
ii) use the data to encode a QR code,
iii) append it to the captured data,
iv) send to printer
I have limited knowledge on linux and CUPS. Appreciate if someone could
direct me to relevant resource for further research.
Thanks in advance!
