Comment 5 for bug 1160638

Not sure if this helps, but on my 64-bit ubuntu machine I was never able to print to my MF4150 printer, I could only scan with xsane. I tried many times over the years, with various ubuntu versions, and only recently, on Ubuntu 13.04 and after upgrading the Canon drivers to v2.70 I was able to print. I don't know if the cups update alone, or the driver update fixed the problem, but in any case I am very happy and thankful I am able to print after years of trying ! I upgraded to Saucy 13.10 and am still able to print and share the printer.
