This is the gouge if you want to print to Windows machine. Here's what I did to print from my iBook with 10.2 to a Windows 2000 machine sharing a HP DeskJet 812 Color inkjet printer...

Go to this link, download gimp-print, and install it.

Do the following (as described in original post) as root:

% cd /usr/libexec/cups/backend
% ln -s /usr/bin/smbspool smb

and then restart cupsd. I think this is what makes "Windows printer via SAMBA" available in the next part...

Now, open Print Center. Hold down option key and select the add icon. You'll get the advanced printer screen. Select "Windows printer via SAMBA", give it a device name (i.e. HP812C), and fill in the Device URI with the something like "smb://username:password@workgroup/hostname/printername". (Note that you can find out if there is a printer shared by running "smbclient -L //hostname"...if one doesn't show up, then you need to share it on the windows side). My string looked something like "smb://charlie:*****@workgroup/Tower/HP812C". You may not need the username or password if your machine doesn't have a password...but who would do that? :-) Finally, select a printer model (I select HP, which then provided an additional list where I selected pcl-812).

You should now be able to print from your Mac to your shared Windows inkjet printer. The output is not perfect, but ain't bad either.

Good Luck!
