A first roller has a first roller center line; a second roller has a second roller center line. Fluid-ejection mechanisms eject fluid onto the media as the media is rolled past the rollers, and include first mechanisms and second mechanisms. The first mechanisms include first and second printheads, at least substantially equally between which a first positioning line is defined. The second mechanisms include third and fourth printheads, at least substantially equally between which a second positioning line is defined. The fluid-ejection mechanisms are disposed opposite to the roller and are positioned such that the first and second positioning lines are located between the first and second roller center lines, the first and the third printheads are not completely located between the first and the second roller center lines, and the second and the fourth printheads are completely located between the first and the second roller center lines.
