please add pixma 2012 series to your app with its driver
Add pixma 2012 series usb driver to your app for android user
unfortunately we are not sure when or if we are going to be able to create a specific driver for this printer. There are no drivers that are known to be compatible with this printer, sorry. But you can try using one of the Generic drivers or drivers designed for a similar printer model by selecting it manually.
Anyway, we will add your printer to the list of requested drivers.
If using generic or similar driver does not help, you can install our desktop app on your computer in order to print using the desktop drivers. Please refer to our official web site for more information.
Note: in the latter case your computer needs to be ON and our desktop app needs to be running when you are printing from your mobile device.
