I have hundreds of numbers to print on a paper and I have this small problem with it.

If I write a code like this:
printer.print 12345
printer.print 123
printer.print 1453

it makes a line of numbers like this:
12345
123
1453

but I don't want them like that... I want them like this:
12345
123
1453

Do you have any ideas, alcorithms etc. etc.?
