We'll start by opening System Preferences, where we chose the Print & Fax preference pane. There you should see a list with all the printers you've currently installed. Click the '+' button to add a new printer. This opens the Printer Browser. Then hold down the Option key and click More Printers; this lets you access the "Advanced" options from the first popup menu.
From the Device menu, select Windows Printer via SAMBA. You can chose the Device Name yourself, but the "Device URI" is a little bit more complicated. It should look like this:
smb://username:password@computername/printername
where:
- username is the username of an account on the Windows computer.
- password is the password of this user on the Windows computer.
- computername is the network name of the computer
- printername is the name under which the printer is shared on the Windows computer.
smb://nele@vaste/kyocera
Finally, select the correct printer model, and click Add.
You should now be able to print to your shared printer.
[kirkmc adds: I can't test the actual printing, not having a Windows computer, but the rest works fine.]
