Canon CLI-42 Genuine 8-Color Ink Cartridge Set | Compatible with PIXMA PRO-100 Printer | Perfect for Professional Photo Printing & Art Reproduction

This is the complete ink set for the Canon Pixma Pro 100 and certain other Canon printers. I continue to get excellent results from a three year old Pixma Pro 100 that does a 8 - 10 large prints at a time, then may be idle for 2-3 weeks or longer. I've never had a problem with clogged print heads. The printer seems to do a good job of maintaining itself after being idle, though occasionally it will give a fault message that clears with a reboot.Each ink cartridge holds 13 ml, a good compromise for this type of occasional printer, as it's more than some 5ml types, but much less than the 80 ml commercial duty models that might dry out before they were spent - and whose ink sets cost several hundred dollars. All things considered, including the pleasure of printing excellent quality prints whenever you choose, I've felt this option to be a good value. Note that you'll never "come out even" with the different inks, so plan to buy an extra yellow or light gray now and then, or perhaps the colors-only set if you don't print many B&W or low-key images.Of course the "Gillete Business Model" is in effect (sell the razor cheap, sell the blades dear), as the Pixma Pro is always on discount, sometimes less than a regular ink set. (the printer comes with a "starter set" with less ink, so be sure to buy a full ink set with the printer.Yes, I'd rather pay full price for the printer and half price for the ink, but even so, I'm OK with the long term cost of the process.
