Enter Start / End Value In Box And Then Loop Value In Cell?

I am working on an excel sheet that asks the user for a Start and End value, to create a print selection. It should then loop all of the numbers between both values into Cell B1, update the sheet and print the page each time.

I think i have the VBA code worked out, except for the fact that i seem to get stuck at the loop action for printing all values between the 2 input values ( i don't really know how to do this).

I have an example of the file uploaded here: Zippyshare.com - Printbarcodes-test.xlsm

Here is the code i am using (the loop/selection part is still missing):

Code:
Sub PrintSelection()
Application.ScreenUpdating = False
Application.DisplayAlerts = False

[Code]....
