OSX HP Color LaserJet CM1312 MFP duplex printing
When I started to use my HP Color LaserJet CM1312 MFP it turned out that manual duplex printing was not exactly working. Page 1 had page 7 on the back etc. The problem was that the printer prints its pages in opposite direction, starting with the last page. I spend lots of time seaching for a solution. I found this website, which descibes how to change your printer driver in order to print from 1 to n. Here are the steps you need to do…
Open a terminal
First copythe driver to a temporary location
Second make backup of this file
Goto your temporary location:
And extract the archive:
Open nano:
Change the following lines:
*DefaultHPFaceOrientation: FaceUp into *DefaultHPFaceOrientation: FaceDown
and
*HPManDupTumbleFirstSides: False into *HPManDupTumbleFirstSides: True
Save the file.
Now we need to zip our driver again:
Copy the driver back to the system library
Now open up your printers preference panel and remove your printer.
Reinstall your printer and the new driver will be used.
You can now use your manual duplex printer!
