Canon Community

I loved this paper and I'm disappointed that I can't seem to find it in a 44" roll any longer.Why did Canon discontinue it?What is a good replacement?

I have a Pro-4000 that I use infrequently (approx one 44" x 60" print per month). I would appreciate any and all thoughts on what regular maintenance should be performed to maintain the health of the printer/print head/ink. Thanks!
