This problem can be nicely solved - but only with money.
Firstly, if you own the full-blown version of Acrobat, you can print .pdf versions of Microstation files from IPLOT, simply selecting Acrobat Distiller as the printer. I've done it and the results are, provided you're very careful with fonts, not too bad.
Secondly, you can print image file (JPEG, PNG, etc.) directly from Microstion's Utilities>Image>Save... menu command. The output is worse than Acrobat's though.
Thirdly, and this is expensive, but will give you exactly what you want. You need an archiving option from the IPLOT server that will virtually plot files in the CAL format. CAL is a black-and-white (sometimes blue and white) raster format, "CAL" stands for Continuous Acquisition and Life-cycle. The MaxView Corporation (
sells a program (called, incidentally "MaxView"

that reads CALS files. There are other companies springing up with CAL readers and authoring tools, so a web search might get you a more competitively priced piece of software. You can install the FREE MaxView reader on everyone's computer, install the MaxView author on a single computer from where the documents originate. Send everyone a CAL version that is full-scale and annotatable, etc.
Hope that round-about story helps you!
