a first satellite print unit printing a first web on a first web first side;
a second satellite print unit printing a second web on a second web first side;
a first dryer downstream of the first and second satellite print units, the first and second webs passing through the first dryer;
a third satellite print unit printing the first web on a first web second side downstream of the first dryer; and
a fourth satellite print unit printing the second web on a second web second side downstream of the first dryer.
2 . The web printing press as recited in claim 1 wherein the first web second side and second web second side face each other passing through the first dryer.
3 . The web printing press as recited in claim 1 further comprising a second dryer downstream of the third and fourth satellite print units.
4 . The web printing press as recited in claim 1 wherein the first dryer includes a chill section.

10 . The web printing press as recited in claim 9 wherein the web guiding device provides a bay window for the first web.
11 . The web printing press as recited in claim 2 wherein the first dryer is located directly above the second dryer.
12 . A method for printing dual webs comprising:
printing a first web on a first web first side;
printing a second web on a second web first side;
subsequently drying the first and second webs in a first dryer;
printing the first web on a first web second side downstream of the first dryer; and
printing the second web on a second web second side downstream of the first dryer.
13 . The method as recited in claim 12 wherein the first web first side is printed by a satellite printing press.
