OSX and wireless (third party) print server problems - 'host is busy' again

Question

The setup:
MBP running OSX 10.5.2
Zyxel NSA-220 (with latest firmware) hardwired to a Lynksys wireless router (running Tomato firmware)
Canon PIXMA iP4500 with CUPS+Gutenprint v5.1.7 drivers
I'm trying to set up the NSA as a print server. I can ping the NSA, it shows up fine in finder and I can access the shares on the discs - all wirelessly.
However the Canon setup program can't locate the printer when it tries to align the print heads, so I tried using Print & Fax to set up IP printing, with LPD as protocol and the IP address of the NSA, selecting CUPS drivers rather than the Canon ones.
The issue comes when I try to print and get locked in a 'Network host x.x.x.x is busy' cycle that never ends. I switched from M$ about 12 months and think I'm reasonably computer literate but feel like a mac newbie when problems like this hit. Grateful for any advice.

Answer 1

I helped another postee with a SimpleShare NAS. Reading the user documentation for the device, it showed the Windows connections using smb, ie you simply browse to the device via Network Neighborhood, double-click then select the printer name.
To use smb on the Mac, you select Windows Printing when you add the printer, then browse to the workgroup, then the Zyxel computer name and then the printer share name. Note that if the printer share name has spaces and too many characters, it can cause problems so keep the name short, such as iP4500, and don't have any spaces.
With regards to the current use of LPD as the protocol, this will be the cause of the network busy error as the device probably doesn't support UNIX print services (which btw is what you need to enable on Windows Server if you were to connect the same way).
One final note. The recent Security Update 2008-002 stopped some users from connecting to their current Windows share. One workaround has been to add the user account information into the queue name. This can be done by modifying the view for the Print & Fax Add Printer dialog box, so that the Advanced Printing option appears. Control-click on the icon bar in the Add Printer dialog box and then select Customize then Advanced. Within this selection will be the option to use Windows Printing via SAMBA. This lets you add the printer with all the necessary info, such as the example following.
smb://NSAusername:password@NSA_IPAddress/iP4500
Once you have entered the queue name, you can then browse to the Canon Gutenprint v5.1.7 iP4500 driver.
