I've been away for a while due to life getting in the way, but have recently been wrestling with getting some half decent prints from my old epson inkjet. I wanted to post what I had found but as it was edging towards software usage I posted as an answer to an old question on askubuntu here. Is it worth copying the question across?
Printer profiling questions in the context of photographic workflow are appropriate, but answering your question, "Is it worth copying the question across?"... generally, no. Cross-posting is heavily discouraged amongst Stack Exchange sites. See this answer to the Meta-SE question, Is cross-posting a question on multiple Stack Exchange sites permitted if the question is on-topic for each site?
