I wasn't suggesting buying a modern plotter, I was suggesting using a printing service as modern large format printers are expensive. Similarly I know pen plotters probably aren't totally out of use, but I can't find anywhere that offers them as a service you can rent (which was OPs question). Pen plotters have actually had a resurgence lately among hobbyists with the proliferation of affordable CNC controllers and stepper motors, but I don't think many professional shops are operating them regularly. I bet there are some artists using them however, as well as occasional users like you.
