As an FYI, I just ran into this problem. When printing 30x42 documents from Acrobat versions 5 and 6, the image will be printed in the wrong orientation in relation to the paper which results in getting a 30x30 image on a 30x42 sheet. PlotBase correctly rotates the image, but since there isn't any print data sent from the application for that extra 12", that part comes out blank.
I loaded Acrobat 7.0 and it printed fine. The print still comes to Plotbase in the wrong orientation, (42x30 instead of 30x42) but all the data is there and PlotBase rotates the page automatically onto 30x42 paper and all the data is present.
