Upgrading to 22.04 printer doesn't works in Color

After Ubuntu upgrade to 22.04, the printer Nashuatech Aficio MPC2051 print only in Black/White and doesn't print in COLOR mode:

I tried to reinstall drivers.

In Ubuntu printer setup if i select 'Color' then reopening Ubuntu printer setup I always find 'Grayscale'. It doesn't store 'Color' mode.

I tried running Bash file Test_Stampa_COLORI.sh :

#!/bin/bashlp -o ColorModel=Color -o media=a4 -o fit-to-page "test_color.pdf"

I tried also using Generic Printer Drivers.

But always print in B/W.

With 21.10 the printer works also in color mode.
