How would you centre text when printing it?

And how would you line the contents of a listbox up. For example i have 2 list boxes and want them to print out on the smae piece of papoer. On the first listboxes are descriptions (different lengths) and in the second are prices How would i line up the decimal point with the one above when printing.
The two listboxes are being printed side by side
