Reports can be emailed using the Report->Send To->Mail Recipient (as Attachment)... menu command when print previewing the report.
If you want the emailed report to look exactly like the printed report choose the Snapshot Format. Snapshot files are viewed with Microsoft's Snapshot Viewer. If you have the PRS, Office installed then you will probably already have the Snapshot Viewer installed, if not it can be downloaded for free from the Microsoft Web Site http://support.microsoft.com (search the site for Snapshot Viewer).
If you want to send reports, invoices (or indeed any printed item from any application) as PDF files we recommend installing a PDF printer driver. For example pdf995 (see http://www.pdf995.com).
The PDF Portable Document Format was developed by Adobe and is an industry standard document interchange format (the free Adobe PDF Reader program can be downloaded from the Adobe Website (http://www.adobe.com).
