With regard to the post by Tom Smith ....
UK also manufacture Paper (for both B&W and digital), and pigment ink.
USA do not manufacture - they import from the UK.

With regard to the post from Jade....
UK Sales are still employed (although most of the rep's have gone) and there are still some marketing bods around. R&D...not sure, but probably 99% have gone.

UK production of film and paper is still underway. We are hopeful that someone will come along and buy us (we are officially "for sale" in the financial times!)
