General :: Connecting To Windows 7 Share Via SMBClient

I am trying to allow my mother's Acer Aspire One (OS: Linpus Linnux Lite) to print on the WIFI Canon Pixma MP620 printer. The rest of the computers connected in the house run some variant of Windows. The printer has been set up to print wirelessly from the Windows computer. Having searched the internet for hours, I have determined that there aren't any drivers for that particular printer.

My potential solutions are:
1. Buy a new printer
2. Install Windows on the Aspire One (Last resort!)
3. Use this piece of software (http://www.printeranywhere.com/), which is installed on my Windows 7 computer which is on 90% of the time, and find some way to install it on Linux. (I tried Wine, and it opened up the installation .exe but when it came to actually installing, returned an error saying it needed to be installed on the same drive. :S)
4. Follow this tutorial (http://justin.yackoski.name/winp/) to print via my computer.

I think I will manage to follow the tutorial fine (as a complete Linux novice!), but I am having some problem with simply connecting to my Windows share folder, which I came across on this line of the tutorial: Test that you can access the share from the linux PC via smbclient. I.e., run: smbclient //windows_pc/spool -U print and make sure you can put a file into that shared directory. After I enter the password, as prompted, is returns:

session setup failed: SUCCESS - 0

When I try: "smbclient -L //WILL-PC -U Will", and then enter my password as prompted, it returns the same error. However if I try: "smbclient -L //WILL-PC -N", it returns: Anonymous login successful. Then my correct Domain, OS and server details. Then the titles: Sharename, Type and Comment

And then the following:
cli_rpc_pipe_open: cli_nt_create failed on pipe srvsvc to machine WILL-PC. Error was NT_STATUS_ACCESS_DENIED
Error returning browse list: NT_STATUS_ACCESS_DENIED
Anonymous login successful
Then the same correct Domain, OS and server details
Then two headings: Server and Comment, each of which have a different entry below them to do with my printer.
Then the two headings: Workgroup and Master, below which there are two different workgroups that we have, and my computer and my sisters laptop.
