I recently purchased the TR8520 but am unable to print in draft mode from my Mac (OS 10.14, Mojave). The three printing choices appear - draft, normal, and best - but when I drag the arrow to “draft” and release it, it jumps back to “normal”. I’ve spoken to customer support at Canon and Apple, who pointed fingers at each other. Finally the Apple rep suggested I ask the community. Can anyone help? Thanks!
I had the same issue, it's simple to solve.
We need to download the drivers from canon website and use them instead of the automatically assigned airprint driver.
Copy&past from apple.stackexchange comment that helped me.
On the latest versions of OSX (e.g. tested with High Sierra, 10.13.2) there is a seemingly handy option to add "nearby printer" which lists printers the OS can auto-locate. The problem is that this option defaults to using airprint and never gives the option to change the print driver with the "use" drop down.
To fix this (see also this Epson-focussed exchange on Apple community), reinstall the printer using the printer-specific driver:
This should now use the manufacturer customized printer dialog including the option to select "Fast" for "Print Quality" under the "Quality and Media" option set.
I sold my Pixma as as fast as I could to a PC person. It looks like Canon is never to create drivers for the Mac. I am very happy with my new printer--an Epson printer, which includes drivers. Ink will always be expensive, but the Epson has 4 Print Settings. For PDFs, it's called Draft, for other documents, it's called Fast Economy. I will never buy a Canon product again.
