you can do both ways. i generally book it at home and take a printout later at leisure. another option is : if you have microsoft office- onenote, then after booking when it asks if you want to print it, click the print option and then choose onenote as the printing destination and then go to that file in onenote, open it, copy and paste it onto microsoft word as a word document. then you can easily take it in a pen drive.
