Question about HP Tango X

I don't need the Tango to print photos, but because of the format I assume that 20x25cm would also work. However, I myself have a lot of trouble with the colour cartridges clogging up. Probably because I print too little in colour ....

8x10inch is possible and available in the dropdown menu. I use the 10x15cm(4x6in) and the 13x18cm (5x7in) and am very satisfied.
