Photoshop- Print size and DPI question?

I'm not very good at photoshop, so please help!

I have a picture on photoshop and hope to get it printed on some t-shirts. The printer's requriements are that the image has to be 300dpi and actual print size at 100%.

How do i change the dpi (is that the same as changing ppi?) and how do I change the print size? The print size is only at 24%.

Thanks in advance

A dot is a pixel, dpi is dots per inch, and a ppi is a pixel per inch, so it's the same thing yes.

When you print you have to print in such a way that it has to stretch onto the size of the paper, and you type that in inches to photoshop and print to fit the page.(Stretching)

So here's the thing, I don't agree with the other persons post. But mine may be a bit advanced so i'm just going to say, if you want one of my experts (like Ben Willmore) to show you this in Photoshop on a video Tutorial, you need to check out xTrain.com's training, he does a fab job explaining DP

I, PPI, Print Size and print Resolutions (which is what the other poster got you into, but in enough trouble that i'd seriously watch Ben's Class)...

As far as answering your question... There are some basic things you need to find out about your work before I can answer more questions....
