Macro For Standard Print Button

Hello again. I have a slightly difficult problem here. I need the Standard Print button to print only the number of pages I've entered in Cell X1 when I click it, (and if I haven't entered any value in Cell X1, nothing should be printed.)

Now, where this gets tricky, is that I still want to be able to override this automatic number printing if I want, by selecting 'File/Print...' from the menu and choosing a different number of pages to print.

Can this be done?
