If the printing component of the MX fails to appear, which will be seen as "canonijnetwork" in the Kind column, but the scanner components does then it would suggest either a problem with the driver, as this installs that Canon protocol, or with something blocking the protocol if installed and working.
I see that you have reinstalled the drivers but I would suggest you trash the BJPrinters folder, located in HD > Library > Printers > Canon. With the folder trashed and the Trash then emptied, will would connect the MX via USB so that the driver is downloaded and installed. Once this completes, then disconnect the USB cable and with the printer networked, see if you can add the printer.
If the printer component still fails to appear, and yes it does take several more seconds to appear compared to the scanner that uses Bonjour, then you can enable a setting in the MX for a workaround. You will need to access the internal web page which you can do by entering the MX's IP address into a web browser. If you don't know the IP address then you can use Bonjour to find the MX on the network using Safari. With it open, select Bookmarks and Show Bookmarks. Then select Bonjour in the left sidebar - the MX should be listed in the right pane. Select it to open the internal web page. On the MX700 home page there will be an Advanced button. Press this and then select Other Settings in the left sidebar. From this Other Settings page there is the "LPR Service Notification" setting. Enable this and then OK the change. Exit from Safari and open Print & Scan again to add the printer. It should now appear with Bonjour in the Kind column.
