1. A printer comprising:
a print station;
a media transport mechanism arranged for conveying print media on a transport path past the print station, the transport mechanism having a support surface for supporting the media; and
a vacuum device arranged for attracting the media against the support surface on a section of the transport path downstream of the print station,
wherein the vacuum device is divided, in a direction along the transport path, into at least two segments in which the media are attractable with different non-zero suction pressures, and
wherein the vacuum device has an upstream segment and a separate downstream segment,
wherein the suction pressure in the upstream segment is larger than the suction pressure in the downstream segment, and
wherein a ratio between the suction pressure in the upstream section and the downstream section is between 1.3:1 and 5:1.
