What do I do with my Bonus rewards? buy Paper for my two HP printers. I still have two reams if it left! It will last for a long time. NO printer or paper jam-free It is how you handle the paper befor you put into the trays or rack! The prnter descrives what you do to make a nice perfect aligned stack. I have my own method I learned by the old IBM punched cards.It works flawlessly. Double sided is more tricky that prints on one side at a time the paper gets dog-eared rendering it not a good idea to send it in twice!
