Two-Sided (Duplex) Printing with HP C4780 Not Working

[Saladsamurai]

Hey folks,

I recently got the HP C4780 printer free with the rebate deal. It says that it can two-sided print, but the option is grayed out. Any ideas? Everything else seems to work. Anyone else having this issue or have any ideas? My next move is to download drivers from site, but I hope I don't have to reconfigure the printer, so I am holding out for a few.

Thanks.

Grayed out:

I've got the same printer and done some research as I was wondering the same thing. Apparently HP hasn't updated the driver for Snow Leopard and this printer yet to support duplex printing.

Yeah. I called support and they said you have to do it manually (i.e. print odd and then rotate and print even). LAME.

Is yours setup over a wireless network too? Mine takes approximately 2-4 minutes from the time I hit "print" till the time it actually starts printing. You have these problems?

Yep. It doesn't take that long, but if I'm closer to the printer, it's quicker. That's just how wireless printing works (nothing you can do).

Hmmm. I'm 4 feet from the printer. Not sure how much closer I can get. Once the printer receives the data there's no reason for it to take so long ... so I wonder why the printer takes so long to get the data?

I might try to exchange this thing.

That is not how wireless printing works. Your distance from the printer makes no difference whatsoever (unless you're running in Ad-hoc mode, but then you wouldn't have internet). You need to be closer to the wireless source (router, AP). Having both the printer and your computer closer to the router would speed it up, but only by a second at most (And that's in extreme circumstances).

Taking anywhere over 10 seconds to start printing (more if it's in some sort of powersave mode and needs to start up, of course) indicates some sort of problem with the drivers or the printer itself.
