Public Service Announcement
I just want to be sure everyone knows this. Just in case nobody has filled you in.
When your computer pops up a message telling you that your printer cartridge is almost out of ink, it is a big, fat, pernicious lie. You've got plenty of ink in there so leave it alone. Don't pull that old cartridge until the last page you print is all fadey and hard to read.
The people that make the ink cartridges are merely trying to get you to throw yours away early so that you'll buy more. They'll tell you they've got 8 kids and baby needs new shoes. They lie.
It is a scam. Kind of like insurance, atheism, and interest-free credit cards. Only not as bad.
