8d) If we mind our Ps and Qs, we can't miss these printing features. (9) e-t-n-e-s I think the answer is extenders but can see no cryptic involvement, plus the whole thing seems somewhat vague. What do others think?
Thanks - I knew they were to do with printing but they seemed to be inks rather than 'features'. It certainly seems the best answer. Thanks to everyone for their suggestions
Incidentally the setter may have made a mistake: he seems to be referring to the 'tails' on lower-case ps and qs - which are normally known as descenders not extenders.
