Printer

Today we bought new ink cartridges for our printer. I have always wondered why each time we replace them we are prompted to print a test page or align the cartridges. I don't think we have a choice in the matter. It just does it!! To me it seems to be a waste of ink. It might be the brand of printer that we have, I am not sure. I just know that we were in need of a new cartridge and I'm glad we have it now. I need to print off my Christmas letters this week.
