Thank you for your inquiry, and welcome to the Canon Forums.
We appreciate your participation, however, for the community to best assist you can you provide us with the model name of your printer?
If you live outside the United States, please visit: https://global.canon and select your country or region for your support needs.
The printer was retired some years ago and the last driver made for this printer was for OS X Lion 10.7. While there is no driver for the Mojave 10.14 operating system there is one for OS X Snow Leopard 10.6. On your Mac with Snow Leopard, please click the link below to open the support page for the printer. .
You will want to download and install the iP1700 CUPS Printer Driver Ver. 10.51.2.0. You can try that driver on your Mac with the Mojave operating system but I can't guarantee that a driver for 10.6 will work in the 10.14 environment.
