How to get an HP and Canon printer to work in Snow Leopard?

"The HP was simple. First I ran software update and installed the HP printer driver update. However, it still said it needed updated software after this, so I removed the printer and reinstalled it. It printed perfectly after this.

The Canon was a bit tougher. I downloaded and installed the Canon printer driver update, but this probably didn't make a difference because the iR C3220 is not a supported printer on the Apple site.

Next I downloaded a fresh copy of the driver from here imagePASS-C1v2.1_PPD_Intel_MacOSX.hqx

It installed correctly, and I removed the printer and reinstalled. Tip: the printer doesn't show up using Appletalk anymore, so when you add the printer, choose IP on the top, select Line Printer Daemon - LPD. Type in the printer's IP address. For the Queue, type in print. Under Print Using, choose the Canon iR C3220-C1 ppd.

It still wouldn't work, so I checked the cups error log file. From terminal, type:

tail /var/log/cups/error_log

The error I was receiving was:

Filter
""/usr/libexec/cups/filter/fierycupsfilter""
for printer ""_11_22_33_44"" not owned
by root

The fix was easy enough:

sudo chown root:wheel
/usr/libexec/cups/filter/fierycupsfilter

I had to remove the printer and add it again, but after that it worked.

I found absolutely nothing when searching for this on the internet, so hopefully this helps someone else who may be using this combination. There may be similar problems with other fiery-based printers."
