printing part of a page without feeding entire page through printer

Question

I am working on an app in VB.net that needs to print labels to an older dot matrix printer. I have the labels printing correctly, however when i finish printing the printer feeds the rest of the page through, even if some labels are unused. I would like to be able to print a few labels and then have the printer just move on to the next label and stop. Any ideas how to do this would be greatly appreciated. Thanks. dmalcom
