Sorry, what I have asked you for in the previous comment is not correct in this case, you do not need to do it. Instead, do the following:
Run the command
lpadmin -p testipp -E -v ipp://NPI61F41D.local:631/ipp/printer -m driverless:ipp://NPI61F41D.local:631/ipp/printer -o PageSize=A4
Test this queue by the following 2 commands:
lp -d testipp 170x230.pdf
lp -d testipp -o print-scaling=none 170x230.pdf
Independent whether you get a correct or wrong printout, please attach the error_log and /etc/cups/ppd/testipp.ppd
