nothingcrat: The reason you have printable versions of a page is to make sure its styled so that when it prints it can be read.
Sometimes font colors, or other options (esp when using b & W printers) don't always print exceptionally readable. Then there are links. When you print a page you can see the link, but not see where it goes without special formatting. Soprint pages often time list the URLS next to the hyperlink, or like in my case, as a list at the bottom so people can reference where to go for the links in the page.
As to the original question:

herePrint page:
1) Create a new Individual archive Template called Print Friendly.
2) Design the layout of the page as you want it to appear. Most times addin a simple STYLE attribute to the top and listing the CSS there is simpler than creating a new stylesheet as there will be way less styles.
3) Go to Blog Config/Archives and add it as an individual Archive type. MAke sure it outputs to a different name than the individual archive. Mine is print-<$MTEntryID pad="1"$>-<$MTEntryTitle dirify="1"$>.php which outputs as print-00001-title_of_entry.php.
4) rebuild and add the print sheet to your blog.
This is the simplest method for me. Downside is that every individual archive has two copies of itself, the normal and the print version.
There are other ways to do this with CSS and such, just search the archives.
