We have a HP 1050c+ plotter. It used to be that most of our plotting was 24x36 so those of us who plotted 30x42 sheets just had to trim our sheets. Well, now most of our plotting is to 30x42 so we decided to buy 30" rolls. Thing is, with the new plotter we can't get it to rotate the plots automatically like it would with our 755cm!!! I went to the "printing preferences" and checked the "Automatically rotate" from the Advanced tab, but it still won't do it. I went to the plotter and checked the paper settings and there is a place to tell it to always rotate 0, 90, 180 or 270 degrees, but no way for it to "automatically" rotate. We tried recreating the PC3 file, but still no love! We can change it to print portrait and it will work, but it won't stick. Any suggestions? Lila
