How do you Export?

They can bring it back up but there will be a loss in resolution, some of which would be correctable through the tools provided by PhotoShop and Lightroom.

I think you're referring to upsampling. Changing the dpi only affects the image width if you tie the physical dimensions (inches) to the dpi/ppi. This is a Photoshop option but I don't think LR behaves that way. A 2000px wide image will always be that wide unless you up or down sample it.

If you export an image at 2000px wide you could print it at 6.6 inches wide, which is 300dpi. 300dpi would be regarded as high quality. The thing controlling it is the pixels wide divided by the dpi you are prepared to accept. If you're good with 200dpi which is not exactly terrible you can print it 10 inches wide. If you printed at 72dpi which is rubbish you would have an image 27 inches wide. It's a bit like giving someone a 500bhp car and saying it can only do 30mph because we have speed limit signs up.

With regards to printing a picture, I normally just select the option to fill an A4 sheet and the printer does not care less about dpi.

Makes sense...
