Besides grist mills to produce flour, there were numerous other types of mills along Chester Creek including sawmills, textile mills, and papermills. There were two papermills downstream from Newlin Grist Mill. These turned linen and cotton rags into paper for writing, printing, and currency. The iron paper press here (mounted on a reproduction wooden frame) came from Trimble's papermill and would have been used to squeeze water out of the paper pulp and compact the fibers into smooth sheets of paper.

The most well-known papermill in Concord Township was Ivy Mills, owned by the Willcox family and located downstream from Newlin Grist Mill on the West Branch of Chester Creek. Started in 1726, it had Benjamin Franklin as one of its customers and would go on to produce the paper for Continental currency. Ivy Mills operated until 1886--its ruins can still be seen today along Polecat Road (the eastern boundary of NGM), near Ivy Mills Road. But from 1796 to 1817, the Willcox family had nearby competition--William Trimble, Jr. also operated a larger papermill along the same creek during that period. William Trimble, Jr. closed his papermill when he purchased Newlin Grist Mill.
