"print" method on transparent background produces black fringe

# Expected Behavior

Printing text on a image with a transparent background should result in text with a transparent fringe.

# Current Behavior

Instead of a transparent fringe, the text is drawn with a black fringe.

# Possible Fix

In the drawCharacter method of plugin-print, changing:

`image.blit(characterPage, x + char.xoffset, y + char.yoffset, char.x, char.y, char.width, char.height);
`

...to:

`image.composite(characterPage.clone().crop(char.x, char.y, char.width, char.height), x + char.xoffset, y + char.yoffset);`

...seems to "fix" the fringe. There may be a more efficient way to do it though!
