Pdf's are correct on computer but when printing come out upside down
So, I have been having issues with printing PDF's on our Ricoh large format printer. The pdf's will look fine when I am going through the documents on the computer but when I print them there are various pages that come out upside down. I initially went to the printer people with this problem but they swear up and down that it is an adobe issue.. Even though I feel like I have done everything in my possibility to correct it . It is just a waste of time when I am printing a 200+ page job and 15 of the pages come our upside down and I have to go through and make sure all is correct. .Please tell me there is a solution to this.
