Like the previous poster I've never seen a difference. I'm careful with my paper fixing, but I have to admit I'm far more likely to over-use my film fixer, no of films not time. The negatives I made while at school 40+ years ago are still fine and all made since.
My litre of Hypam (1+4) must have fixed at least 20 rolls of 120 Tmax400, FP4 & HP5 as well as about 80 sheets of 5x4.
Prints, well fibre based anyway, need fresh fixer because some of the equilibrium complexes formed between silver halides and thiosulphate get left in the paper base if the fixer has to high a silver content. Also the iodide content from film fixing can hinder good paper fixing.
