HP 1310/1315 won't print anymore

[Stupot]

I screwed my printer up a while ago, so hopefully I'll remember everything right. I was trying to make it print the pages in reverse order and read somewhere that I could use lpadmin to do so. Well, I tried and it didn't work so I tried setting it back to normal....long story short, I can't print anymore. I'm not sure what config files need to be changed. I removed the printer and attempted to add it again and I can't seem to add it anymore via the control center or though hp-setup. Any help would be appreciated.
