How to print out files in the (.pdf) format

PDF format is a file that is independent on the computer. A PDF file can be printed and viewed, but one cannot get the source. [according to me]

% cd - to get to your home directory if you are not already there.
% ls *.ps - to see if the file was really saved. In that case you'll find it among the output names.
% lpr - to send the file to the printer. Instead of the "name_of_file" you should type the actual name of the file you wish to print out.
