Share the chart in Image or PDF format then:
• Print directly from your device if you have a wireless printer  (you might need a third party app such as PrintShare) or
• Email it to yourself and print it from a computer

If you want the chord diagrams in the chart, turn on the Chord font you want, here is how.

In case you have a chart that has only 4-5 systems, the printer might default to landscape.
Open the Editor and add an extra character 2-3 lines under the last bar to make sure the chart will be printed in portrait.
