That is a combined CUPS/SAMBA configuration issue. Obviously, your Windows 
originating jobs are tagged as "application/postscript" by cupsd on the 
server and then piped through the usual filter chain which causes the pstops 
(or the pdftopdf) filter to insert the default options known to the server 
into the job. As the number of copies defaults to 1 unless explicitely 
specified, the copies spec set by Windows gets overwritten.

As you say printing the Windows originating jobs with "-o raw", I'd suggest 
to add 
cups options = "raw"
to your smb.conf, which forces those Windows jobs as raw through CUPS.

PS: another approach, which I myself did some time ago, would be to modify 
the pstops filter to not to insert the local defaults into windows jobs, but 
that would be repeated after every cups update, so I don't recommend it.
