HP Color Laserjet MFP m476nw Duplex print problems

[Ron]

I am trying to print in duplex to my HP Color Laserjet Pro MFP M476nw printer, but it always prints on a single side. Here is the output from HP-CHECK:

$ hp-check

This is free software, and you are welcome to distribute it
under certain conditions. See COPYING file for more details.

Note: hp-check can be run in three modes:
1. Compile-time check mode (-c or --compile): Use this mode before compiling the HPLIP supplied tarball (.tar.gz or .run) to determine if
the proper dependencies are installed to successfully compile HPLIP.
2. Run-time check mode (-r or --run): Use this mode to determine if a distro supplied package (.deb, .rpm, etc) or an already built HPLIP
supplied tarball has the proper dependencies installed to successfully run.
3. Both compile- and run-time check mode (-b or --both) (Default): This mode will check both of the above cases (both compile- and
run-time dependencies).

Check types:
a. EXTERNALDEP - External Dependencies
b. GENERALDEP - General Dependencies (required both at compile and run time)
c. COMPILEDEP - Compile time Dependencies
d. [All are run-time checks]

THANK YOU!

[Ron (rong)]

This may seem similar to Question #253598, but I have tried those suggestions and they didn't help.
Thanks.

[Joe (wankelrx8)]

I have the same problem. When I try to print duplex, it only prints single sided pages.

[Ron (rong)]

I'd appreciate any help I can get. It has been one month since this bug was opened. How long does it normally take before a bug is assigned?
Thanks,
Ron

[Gaurav Sood (gaurav-sood)]

Can you guys tell us which application you are using to print duplex.

[Ron (rong)]

Yes Sir. I'm using Adobe Reader 9.

[Joe (wankelrx8)]

I am also using Adobe reader 9.

[Ron (rong)]

I think the M476NW only supports MANUAL duplex printing. The m476dn and m476dw are supposed to support AUTOMATIC duplex printing. In this case, does anyone know if HPLIP supports manual duplex printing? I haven't tried it yet and I'm not near my printer...
