My question: where is that Ghostscript version, i.e. it's executables  
particularly, located in the file system?

It's quite certain that the Ghostscript depending tools will work  
with ESP Ghostscript v7.05. There is one certain case where it will  
fail: you won't see anything in X11. And you will need to enhance  
Ghostscript's Fontmap file to be sure that in any case (while in TeX  
or while printing) all font issues are resolved. By adding the path  
to Ghostscript's binaries to the PATH (or path) variables in a shell  
environment, the TeX tools would find and use them and you could see  
whether something fails.

It's much likely that the newer Ghostscript version will work. The  
problem can be that the Samsung-GDI driver brought in some extra PS  
code and font files. If this is true, it's likely that you cannot  
migrate to the newer Ghostscript version. It would at least make  
necessary to install the new Ghostscript in a place where it cannot  
overwrite the elder software. Then you can try to identify the  
Samsung specific files and copy them to the corresponding places in  
the new version. Afterwards you can rename the old Ghostscript  
directories and create symbolic links instead that point to the new  
directories. By this means the Samsung driver and CUPS will use the  
new Ghostscript version and you can see whether errors happen.

(Are you sure that CUPS uses Ghostscript? Mostly the Apple tools  
should do the job, using /System/Library/Printers/Libraries/convert  
and the binaries from /usr/libexec/cups/filter.)
