Has Cups had any recent updates?

Several of our cad programs have developed a print problem in the last two 
weeks.
No matter which way you print - landscape or portrait it prints it as 
portrait.
Eagle - a PWB layout system has developed this problem - where the user can 
print a one page file or a multiple page plot so it big enough to easily see.   
The boarders and Right edge of drawing is missing.
This has worked perfectly for several years and suddenly it quit working 
properly.   Same system, printserver, printers etc.

Suggestions ?
