Printing an e-mail results in the right side of the e-mail being truncated for all lines, only 78 characters print.
please open the File>Print preview window and check your Print/Page set up settings if the paper size is set correctly.
If it is, please let me know what version of eM Client are you currently running (full version number is found in Help>About section).
6.0.24928.0 ---- the paper size is correct
is the paper size set to A4?
If you try to print a document from Internet Explorer, does the same issue happen?
