I have just discovered that Snagit 8 provides a printer interface, in that one of the options under "printer type" is print to Snagit 8.
The reason I mention it is that you then have the option to save as PDF, and I have used this to save an MS Access report as a PDF document, however I have only succeeded in saving a single page of the report, I haven't been able to get it to save multiple pages into PDF.
There are some instructions, but they aren't very clear, and I haven't got the time or inclination to fiddle about with it. If anyone conquers this are would be grateful for some feedback.
