So how can I print out my entire library of tracks and Albums with the album art, maybe into something like a catalogue format.
How are you storing your album art? Personally, I store all album art images side-by-side in the same album folder as the associated audio files (I also load them into the flac files). Each image is tagged with basic audio information: album, artist, date, date acquired, Last Played (album).
Side-by-side storage enables me to easily manage the images and create Image Views dedicated to album art, each view synchronized in some way to the audio. Once the files are available in an Image View, the album art can be selected and then printed out in a wide variety of page formats using MC's
File > Print Images ... facility.
I have not felt a need to print so far, but it is an interesting idea. It would be labor intensive for a large collection if you have to manually select individual images. However if the folder structure stores only the images you want to print, or you have a way for MC to filter the view for them, then selecting and printing is very straightforward. I think this scheme would fulfill your base requirement to physically page through printed album covers.
I do not know of a way to automatically combine images with text information such as album name, artist name, track titles, etc. But MC text alone can easily be printed out separately after copy/paste into a custom spreadsheet (in Excel for example).
