I use kubuntu 24.04 and Gimp 2.10.38 for printing. You can get Gimp 3.2.4 from a PPA but the gutenprint plugin is not yet updated for Gimp 3.
Usually you need your printer listed in CUPS see: https://www.openprinting.org/printers/ma...urer/Canon and I can not see an ip 8700 but Canon do supply linux drivers and maybe that is the problem with gutenprint. You might have to stick with TurboPrint.
Just as a reference, I have gutenprint set up as: Using Adobe PS level 2 and the ppd file installed by the Brother driver package.
