Is there a difference between paper fixer and film fixer?

No. Usually fixer for films one dilute with water 1+4, for papers you can use 1+4, 1+9 ... it is written on the bottle usually.

Is there a difference between paper fixer and film fixer?

No but once you've used fixer for films it shouldn't be used for papers because of the iodide in the film eulsions.

The biggest difference between paper and film fixer is that photographic paper has mostly Silver Chloride and some Silver Bromide, while film has mostly Silver Bromide and some Silver Iodide. Iodide is the most difficult one to fix, and Chloride is the easiest. As a result you can use weaker fixers (more dilute, Sodium Thiosulfate instead of Ammonium Thiosulfate, ...) for paper than for film, and as Ian already stated, you shouldn't fix paper with fixer that was already used for fixing film.
