You can’t spend all day in front of your computer. Sometimes you need to go out, but you still need to be able to contact people. Enter Address Book Reports.

This app provides flexible and useful print-outs of the contact information in your Address Book. It offers significant improvements on Address Book’s built-in printing.

Its Card and Phonebook styles are ideal for slipping into a Day planner, Filofax or diary.

Address Book Reports also allows for custom page sizes for the reports, so hipster-wielding retro-tech GTD fans are catered for as well. 3″ x 5″ print outs are just a few clicks away.

The main window allows you to chose which fields to print for each report style and whether to print the lot or just specific groups:

The app can also print envelopes (US and international sizes) and labels (Dymo, Avery, even a POSTNET bar code).

Address Book Reports is shareware (USD 15) and available from the developer’s web site, where you can also check out some sample print-outs.

Alex Valentine asks, “Please tell me, is there a way to add color labels to your messages, like one can in Eudora?”

Yes, there is. In fact there are at least three ways to do this in Apple Mail:

1. Use the Label Scripts collection of AppleScripts.
2. Set up rules in Mail Act-on that will colourise the background of emails in Mail.app on the fly with a keystroke conbination. This is what I do, also setting a MailTags keyword which tells my smart mailboxes what to display.
3. Use the tutorial and AppleScript provided in this hack on O’Reilly.com.
