Forcing hp2400 to print double sided

Needed to print a set of labs for a new version of a course. Run out of time, and although the manuals are being printed, the labs documents had to be done by hand! So to save the Amazon, I managed to get my printer to print double-sided! Although this is specifically for the hp2400, the algorythm of printing sequence and which way at which stage should be useful for any printer...

1. Ensure all documents have an even number of pages

2. First print the even pages with the last page on top.

Select File --> Print...

- in "Print:" drop down menu select "Even pages" (default is "All pages in range")

Then select "Properties" --> Basics

- in "Page Order" mark "Back to Front"

Then press "OK" in Properties screen, and "OK" again in Print screen

3. Replace the paper

Pick up the freshly printed pages. Keep them together, in the same order they were printed and the same side up (i.e. printed side up). Rotate the whole bunch 180 degrees horizontally and insert in into the paper tray. Once in the paper tray, the orientation of the paper should be such that one can read the pages correctly, with the highest even page at the top.

4. Print the odd pages with the ultimate result having the first page on top.

Select File --> Print...

- in "Print:" drop down menu select "Odd pages" (default is "All pages in range")

Then select "Properties" --> Basics

- in "Page Order" mark "Front to Back"

Then press "OK" in Properties screen, and "OK" again in Print screen
