Help with 300dpi

I feel kind of embarrassed to ask this question because I have been using PhotoShop for quite some time.
However, I have been doing only web-based graphics and I never cared about printing and about the technical stuff behind printing.
I don't even have a printer, it's that bad.

Now, my problem is that I want to send a graphic file to somebody and they require it to be 300dpi, so to be able to print it.
So, I just upped the 72 dpi of the image document to 300 and it got scaled up and became blurry (which is normal and I have no problem with that).
So far so good...

The problem is that when I rick click and do "Print Size", to preview the newly created 300 dpi file in its actual size, it looks blurrier than before the stretch!

I mean, obviously it's normal for the image to become blurry when you preview it stretched out, but why does the it look blurry in its shrunken down Print Size too?
Isn't it supposed to go back to its original quality when PhotoShop shrinks it down for a "Print Size" preview?
I assume it will appear blurry on the print paper too.
Is there a way to fix that? I just need a quick fix (if there is one).

Thanks!
 
My guess is you blew up the image dimensions when you increased the image resolution. Which is why it looks blurry when print previewed.

Check on the blown up image dimensions....
 
Yeah I have to agree but The main thing to take into consideration is when you designed and made your image/document you had a resolution of 72 pixels per inch if it is 72 pixels or 300 pixels that pixel size per pixel is exactly the same. so if you start of with with 72 pixels when you change the resolution to 300 then photoshop has to paint in its own pixels a bit like how the clone tool works. So it will take information around each pixel and and stretch it replacing it with its own pixels of similar colours. and not pixels you have actually painted into yur image. Hence you loose your sharpness.
 
You should do all your work at high resolution 300-400 PPI. You can lower a high rez image easily, but going the other way is a always a problem.
 
you're screwed bro. No matter what the work you're doing, as a designer your default canvas dpi should be 300, just in case your client decides they want to print. Either that or design in Ai.

It's a shame, but sorry pal there is not much you can do :(
