Printing to PDF is distilling the PDF and you lose all live transparency and interactivity, along with layers and style color management information. Exported PDF may or may not contain live transparency and interactive content, as well as layers and color management information depending on the settings you use.
What you are describing is typical of pages that have transparency or a transparency effect like a drop shadow interacting with text, but without seeing the file it's nearly impossible to say for sure what is happening.
Exactly what settings are you using for exporting PDF? That could make a tremendous difference.
At Adobe, for print purposes, we would recommend PDF/X-4.
Also, how are you printing the resultant PDF file? From Acrobat or Reader (and what version)? Or does your printer supposedly support direct PDF printing?
Peter Spier, thank you for your answer!
Yeah, i'm aware of the transparency difference, but this is simple plain 100% black text/letters. Theres no transparency involved.
Dov Isaacs, when using the export feature, i'm using the preset 'Press Quality' profile in InDesign 6.0
I'll try the Standard you're suggesting, to see if it makes any difference. Though in this test (export vs print to pdf), no standards were used in neither of the two PDF's, so i don't think that's the reason.
Im printing the PDF's from Acrobat Pro (newest version).
I'll try and provide som actual pictures of the problem that's occuring, along with the two PDF's later today
Check that when you export to PDF, then go to Print that the setting for 'Size Options' is set to 'Actual Size' rather than 'Fit'.
'Fit' usually squishes the pages down a fraction and causes text to seem like it is dipping between bold and regular.
I had a Konica Minolta printer and had to get a Postscript Driver to install on the computer. It shows up as a new Printer on your computer.
This resolved the issue.
SteveE91: The same print settings were used on both PDF's, so that should rule that out. Thanks for the input though, it was a good suggestion!
Eugene Tyson: I'll try and get a .PS driver installed. Sadly that will have to go through IT secur. so that could take some time :-)
Thank you all for your great suggestions, and for your help in trying to solve this minor problem.

Have you tried setting up a new document, typing some text and repeating the process? See whether it is the file you're currently working with, or whether it may indeed be related to the printer.
