Best printers are either HP, Epson or Canon or Postscript compatible printers? Avoid Lexmark and GDI printers.
As a lot of the printers are now USB, the Amiga drivers are no longer any good. Get Turboprint 7.1 or later.
Best Word Pros are wordworth and Final Writer (both have stopped production ages ago), so look out for them. Try
