A printer includes 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. The vacuum device is divided, in the direction along the transport path, into at least two segments in which the media are attractable with different non-zero suction pressures.

A filter device for filtering ink for delivery to at least one drop forming unit of a print-head in a printing apparatus includes: an inlet for admission of ink to the filter device; a first filter member adjacent the inlet for filtering the ink as the ink enters the filter device; a collection chamber arranged below the first filter member for collecting the ink after the ink passes through the first filter member; and an outlet for delivering the ink from the collection chamber to a reservoir for supplying the at least one drop forming unit. The collection chamber includes at least one flow directing member defining at least one predetermined flow path, especially at least one circuitous or indirect flow path, for the ink through and/or around the collection chamber to the outlet. Furthermore, an ink supply system for supplying ink to at least one drop forming unit of a print-head in a printing apparatus includes an ink melting device for melting solid ink elements, such as toner pearls, to form liquid ink; a filter device according to the invention for filtering liquid ink from the melting device; and a reservoir for storing the liquid ink received from the filter device for delivery to the at least one drop forming unit.
