This appears to be a regression from Solaris 10 and Solaris 11.3. 
Although they lack /dev/full they do have other ways for printf to fail, 
e.g.:

   ulimit -f 0
   trap "" XFSZ
   printf "test" >test || echo failed with status $?

which issues the following diagnostics on Solaris 10 /bin/sh:

   printf: write error: File too large
   failed with status 1

and the following on Solaris 11.3 /bin/sh:

   /bin/sh[3]: printf: write to 1 failed [File too large]
   failed with status 1

but I guess quietly succeeds on Solaris 11.4 (I lack easy access to a 
Solaris 11.4 box).
