Hi, I'm Nathan.Sorry to hear that you're having trouble, but I'll do my best to help you. Please give me a few moments to review your details here.
If you try to make a copy on the lexmark, direct from the glass (rather than printing from the computer), how does that come out?
My apologies for the delay. The site is not quite instant, but please try to send only a single response and allow me time to receive it and respond back; multiple messages can get lost in the queue and further delayed.
What you're experiencing is a glitch in the windows home mail client. I'd typically suggest uninstalling and reinstalling it, but none of the components for mail or even vista are supported at all any more and none are available for download.
Have you considered trying to access your mail via a web based client, and printing via the browser, instead?
If the email account is set up as an imap account (not pop) they should be still available in the history there.
Otherwise, try using the ctrl key + P key to bring up print command, or worst case perhaps you can copy/paste the email content to a word doc and print from there.
