An inkjet printer, comprising:

• an arched printing unit having first print bars arranged along an arc on a first side of the arched printing unit and second print bars arranged along an arc on a second side of the arched printing unit;
• a dryer positioned within a footprint of the arched printing unit, the dryer having a first dryer part positioned under the first side of the arched printing unit and a second dryer part positioned under the second side of the arched printing unit;
• and
• a plurality of web guides arranged to guide the web along a duplex printing path:
• past a first one or more the first print bars for printing on a first side of the web;
• then through the first dryer part for drying of the first side of the web;
• then past a second one or more of the first print bars for more printing on the first side of the web;
• then through the first dryer part for more drying of the first side of the web;
• then past a first one or more of the second print bars for printing on a second side of the web;
• then through the second dryer part for drying of the second side of the web;
• then past a second one or more of the second print bars for more printing on the second side of the web;

A duplex web printing path, comprising:

• a first quadri-circular arced printing zone in which a first side of the web is exposed to first printing elements;
• a first drying zone downstream from the first arced printing zone in which the web is exposed to first drying elements;
• a second quadri-circular arced printing zone in which a second side of the web is exposed to second printing elements, the second arced printing zone located near the first arced printing zone such that the two printing zones together form a semi-circle;
• and
• a second drying zone downstream from the second arced printing zone in which the web is exposed to second drying elements.
