But, it would help if you said what kind of Canon print queue. If you're talking about a little, consumer-grade printer, a CUPS monitoring solution that the one you were recommended, is the best bet. If you're talking about a big ImageRunner device, you can load the software from Codehost, which gives you a good look into the queue, and all the features.
