[X4U] Printing PDFs without crop-marks...

[Stroller]

I've just purchased a CD-ROM containing a selection of back-issues of a 
small magazine, which are supplied in PDF format. The PDFs have a 
crop-mark on each side and a timestamp as a header, presumably just as 
they were sent to the printers.

I haven't tried printing these articles yet, but I'm assuming Preview 
will include the crop marks and header in it's output. Is this the 
case, and if so how do I avoid it? I suppose I could manually crop each 
article, but I was hoping there would be a way to do this 
automatically.

I have Adobe Acrobat Professional, but am not terribly familiar with it 
(it was included as part of the Creative Suite, which I bought for 
Illustrator & the other tools) - perhaps this might do what I require?

I intend to print in colour on a Canon Pixima IP3000, for what it's 
worth.
