TP7.0 Printing

Hello, this is my first message to a newsgroup, so I hope it goes
through!  My question is:  I have Turbo Pascal v.7.0 running under
Windows 95.  It works fine, but when I "exit to DOS" to toggle the
printer using <CTRL - P>, nothing happens.  I can "print screen" OK, but
cannot print a run directly.  Any ideas why?  Thanks!
