They also do large format printers but these start at £2,600 but do take a roll. I know in the past some Epson A4 printer had an attachment for converting to a roll printer, but couldn't locate on on their website. Might be worth contacting them to find out.
thanks for the reply. My late uncle had an Epson with a roll attachment a few years ago which is what prompted the question really as I haven't been able to find anything similar recently.
I noticed whilst checking their website they still do paper rolls for them. To be honest if you want that option it would be better to use a commerical printers, as they would have large format printer that take a roll of paper. When I was at Ipex a few years ago, they had a printer which would print a size that would cover the front the the average house.
