Since buying my B9180 a few months ago I've always used Canon paper, but recently decided to try HP's own A4 Premium Plus Photo Paper in Satin-matt (280g/m2).
Inspecting the results I'm dismayed to find unwanted lines of dots on the printed media:
Has anybody else had this problem? If so, how is it rectified?
Also, which is the best matt paper to use with this printer?
