Second page of two-page PDFs printing upside-down

in past 2 days, two-page pdfs save out of cs6 printing second page upside down. have tried resaving documents—didn't work. tried saving documents individual pdfs , combining pdfs in acrobat—didn't work. have had colleagues print them, , second page upside-down too. when print two-page pdfs saved last week or longer ago, have no problem @ all. seems happening saved pdfs. didn't update software on computer between saving pdfs printing correctly , when problem began.

 

any appreciated. thanks!

sounds document-sticky printer default may have changed...like duplex-tumble setting. page 2 appear correctly on screen?

 

to troubleshoot here in forum, you'd have provide lot more detail respect methods; perhaps screenshots of related dialogs.
