Last year, my old tower Mac (OSX10.7.5) suddenly began printing out the last page (only) of any PDF with an odd number of pages inverted in both vertical and horizontal axes (i.e. upside down mirror-writing), when doing double-sided printing on our HP Color Laserjet CP4005dn. Single sided printing from the same Mac and PDF worked fine. The same last page also prints correctly if I simply chose to print that page alone. I do not have the 'flip horizontal' checkbox ticked. I could find no solution.
I bought an iMac 27" late 2013 with OSX 10.9.4: all upgrades installed. I still have the same problem. I repeat, this only happens in double-sided printing (selected 'long edge binding' under Layout) of the last page of a PDF with odd-numbered pages. Word .docx and other documents print just fine from the same computer and printer with same settings in the Print dialogue.
Any suggestions?
