Got asked this question today at work and I don't really have a valid answer or explanation for it.
A colleauge in another school is sending many PDFs to another person but when the recipient opens them up they are not showing at 100% - rather at 75% and this is apparantely annoying to the recipient as she has to sort through many of these PDFs every day (sounds pedantic i know - wish she could see what problems i have to overcome in my job as a developer...)
I ran some tests with some other PDFs and had all kinds of sizes (75%, 200%, 148%, etc) some did come in at 100% but not many. I suspect you set the default size when you actually create the PDF, easy enough to do from word and other programs but what about when you are using a scanner (which is what my work colleauge is using). Just wondering if anyone out there has an answer for this because I'm kinda stumped and quite frankly nonchalant.
cheers,
