PDFs are very tricky the rendering engine behind the PDF makes all the difference. Other factors include the type of printer you are printing to (network, IP, Samba, PostScript, PCL/PCL6 etc.), OS, security, and like mentioned earlier, what the content of the PDF is. For example, I created a PDF of an image using Adobe Acrobat 6 (on a PC) tried to open it on the same PC(and others) and the image was completely garbled. Tried it on my Mac(with Acrobat 6 Pro) and it was still garbled. Then tried Preview and it was perfect. As you may know, the OS X interface is done entirely in PDFs and the render engine behind that(which also powers Preview). I believe to be different then the engine powering Adobe Acrobat(other companies, usch as KODAK use PDFs without having acrobat under the hood). This may cause your discrepencies in the viewing. Why it would work in a 98 mavchine and no others is indeed a puzzle but that may lay in the printing side of things or again in the rende ring part. The safest way to do PDFs is to create them in Adobe Acrobat or Distiller(comes with Acrobat), but it is not a guarantee.
