Printing to Windows from MAC OSX 10.2 Printing to a Windows printer is not as easy as it could be on the iMac, but this web site sure did help.

Best tips:

Net View on the Windows box to check the share.
smbclient -L servername -U username on the iMac
smb://username:password@servername/printershare

Note that under Windows XP - the username "Mark Famous" is seen as "MarkFamous" under the iMac. Spaces are removed.
