When you go to add a network printer it should find the printer labelled Canon GX7000 series, or similar or have THINQTANQ in the name. If it does then your work here is done. Click ok to add the printer and remember to select the correct printer in the print dialog box.
However, if for some reason your computer doesn't find it, you can find the details in the set up manual hanging next to the printer which should show you all the additional ways to add the printer depending on your device.
