Yes, I believe you will need to install samba if you want to share the printer.
Then put smething like this in your smb.conf file if it not already...
Code:
# add to [General] section:
printcap name = cups
printing = cups
security = share
# Add to share section
[printers]
browseable = yes
printable = yes
public = yes
create mode = 0700
guest only = yes
use client driver = yes
path = /tmp
