I have a problem that's driving me nuts. I'm getting mightily desperate, to be honest. I have to solve it for my peace of mind before I can do anything else. And that is while it's a beautiful day outside. Man, this sucks. However, here goes... In the meter cupboard (if that's even a word) I have an AirPort Extreme base station. In the living room I have an AirPort Express to which an HP Color LaserJet CP1515n is hooked up. Yesterday I decided to move the AirPort Express a little, so that I'd get better reception further back in the house. The USB cable with which the printer was connected to the AirPort Express was too short to reach the new spot, so I used an other, longer cable. I also changed the AirPort Express from extending the b/g network to extending the a/n network. No big deal. But! Today my printer isn't working anymore. It used to work beautifully before moving the AirPort Express. Yes, I've since tried going back to extending the b/g network. And yes, I've checked the cable. When directly hooked up to my MacBook, the printer works wonderfully with that same cable. But when connected to the AirPort Express the printer fails miserably. It goes into paused mode with the following message: "Unable to write print data: Broken pipe". Extremely annoying! The printer starts flashing its activity light, but nothing happens. I've even seen the printer software not generating this message and still not printing anything while endlessly flashing the activity light. What the heck? I've seen many discussions in the Apple Support Communities (this discussion is the longest and most thorough), but no person with these sorts of problems seems to have found an answer. Where did this problem come from? Just the other day it was all working beautifully. I don't understand! Any help is greatly appreciated.
