Hi djcaetano
I think you may need to look into how samba and cups "hook up" together in order to use a shared printer with cups. I saw a post recently on the gmane.org.netlabs.ecups.devel newsgroup which is probably of interest to you:-
Hi All,
FWIW I just got CUPS to print to a printer that's shared off a Samba
server.
A fixed cupsd.exe is required - it will be available in the next
release.
I had to get this working as my new Qnap NAS only supports printer
sharing using smb - not lpd or ipp

If anyone is interested in testing, I can make the new executable
available.

Paul.
A later post gives this link
http://smedley.info/cupsd-2009-10-04.zipAnother post reveals this possibly useful nugget "URI syntax is smb://username:password@hostname/queue_name" - something to know when setting up the printer in cups :-)
This is not something I've needed to try myself so have no words of advice to offer apart from the obvious you would need to install the samba server on the system with the printer attached and share the printer via samba.
I think the latest samba server is here
ftp://ftp.netlabs.org/pub/samba/server/Maybe 1 day someone will get around to porting the hplip software - Paul seems to be involved with so many ports already that he, probably, simply does not have time to port this package.
Hope the above is of some help.
