Comment 1 for bug 1482748

Hi

Please install the latest hplip-3.15.7 driver.
Download hplip-3.15.7.run file from http://hplipopensource.com/hplip-web/gethplip.html and install it by running command
'sh hplip-3.15.7.run' in terminal.

After install, run command 'hp-setup -r' to delete the existing print queue for this printer and run command 'hp-setup' to re-configure the printer.

This should be able to pick the correct ppd 'hp-color_laserjet_pro_mfp_m277-ps.ppd.gz' for your printer and you should be able to print duplex

Thanks,
goutam
