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

Question

After installing Snow Leopard onto my Mac Pro, I found I was unable to print to either one of my printers, and HP LaserJet, or a Canon iR C3220-C1. So how do you get them to print again? I'm answering my own question below because I couldn't find anything to help getting mine working.

Answer 1

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.

Apple just released updated Snow Leopard printer drivers for HP printers today (9/11/2009). You can install them through Apple Software Update.
