When you say "did not work" what precisely is the issue or error?

Gutenprint's UP-DR80MD support was written in late 2019 via 
reverse-engineering, ie without any support from Sony.

It is certianly possible that Sony changed something during the 
production run, but one of the points of the "MD" model designation is 
that it's a certified device that doesn't change during its extended 
product lifecycle.

A few other things to check with both the old and new models:

 * What is the 'lsusb' output ?
 * What is the output of 'sudo /usr/lib/cups/backend/gutenprint53+usb' ?
 * What is the output of 'sudo /usr/lib/cups/backend/usb' ?
