The invention relates to a device for printing sheets of printing substrate (02), having a first printing nip (12) which is formed between a first cylinder (19; 19*) that acts as a transport cylinder (19; 19*) and a second cylinder (18), and in which the printing substrate sheets (02) can be printed on one or on both sides with one or more collected print image segments, and having a second printing nip (11) lying downstream in the printing substrate path, which printing nip is disposed at a level lying below the first printing nip (12) and is formed between a third cylinder (17) that acts as a transport cylinder (17) and a fourth cylinder (16), and in which the printing substrate sheets (02) can be printed on one or on both sides with one or more collected print image segments, wherein the printing substrate sheets (02) can be conveyed via at least one rotating transport means (33; 38; 39) along a transport path from the cylinder (19; 19*) that acts as a transport cylinder (19; 19*) of the first printing nip (12) to the cylinder (17) that acts as a transport cylinder (17) of the second printing nip (11), wherein on the transport path, downstream of the cylinder (19; 19*) that acts as a transport cylinder (19; 19*) of the first printing nip (12) and upstream of the cylinder (17) that acts as a transport cylinder (17) of the second printing nip (11), at least one first electrode (37; 41) directed toward the outer circumference of the at least one rotating transport means (33) is arranged in an angular segment lying in the transport path for the printing substrate sheets (02) in such a way that when an electric voltage is applied, a printing substrate sheet (02) being guided past the electrode (37; 41) can be electrostatically charged.

A method for printing sheets of printing substrate (02) in at least a first printing nip (12) and in at least a second printing nip (11), which second printing nip is spaced apart from the first printing nip (12) in a transport path of the printing substrate sheets (02) and lies at a level below the first printing nip (12), wherein the printing substrate sheets (02) are printed on one side or on both sides with one or more collected print image segments in the first of the at least two printing nips (12) in the transport path, are transported along the transport path running from top to bottom to the second of the at least two printing nips (11), where the printing substrate sheets are printed on both sides with one or more collected print image segments, wherein the transport from the first printing nip to the second printing nip (12, 11) is carried out by the successive transfer via one or more of at least one rotating transport device (33;
