We have come across this same issue - our users do not have administrator access and therefore cannot get the print client control installed. We are using RS 2005 with Service Pack 1.
We found a Knowledge Base article (http://support.microsoft.com/kb/280579/en-us) that mentions creating an MSI to install the control, but I can't figure out how to get it working.
I was wondering if anyone found any resolution to this problem. I've also heard of people installing the cab files on the client machines, but there is no mention as to where instructions are for doing something like this.
I'm surprised I didn't find many more gripes about this when searching around. Anyway, it would be good to get all the solutions in one place if possible.
Thanks for your time!
