I need the help of the community for a weird problem 

Since I use AutoCAD for mac I can't print my documents directly from AutoCAD to my plotter. Both letter and 11x17 work fine

All my page setup is set to a a1 format when I check the preview the page show correctly, but when I print it always print only to a letter format 

Although if I just print from the preview or from the pdf it all work fine. 

What's weird is that on five different computers we are two persons that have this problem 

We tried reinstalling the printers, but it didn't change anything. 

Someone is already experienced that ?
