Does it skip the second side or does it print it on the front side of the second page?
have you tried any of the other documents that used to print 2 sided? It might be just that one document is set to print single sided.
also you can check the printer driver itself by going to devices and printers folder and right clicking on the printer and selecting PRINTER PROPERTIES
are there any error messages on the printer itself. If the duplex unit is jammed it will stop it from printing double sided.
This might be easier if i can log in remotely and look in the half dozen places there might be an issue.
no problem. Next time your car is broken tell the mechanic he cant touch it either. See how fast he fixes it for you.
I apologize for my mistake. The fact that you are using a Mac was not listed on this page for me to see. We do guarantee our work 100%. Before I send this up for a refund, may I ask if I can remote in at no extra cost and fix this for you?
