I have a cable for my printer that is the small parallel size ( goes in printer ) to serial plugs into computer. My new computer does not have any serial plugs. I bought a parallel to USB but it turns out the parallel on it is the older large size parallel. Is there a cheap large to small parallel adapter in existance? This might be a really stupid question but is a wire splice and switch possible as the large and small look exactly the same except for the size. Any ideas?
