a printer for forming an inkjet image has an advance mechanism for a print substrate . the printer includes an advance mechanism for moving a print substrate in a transport direction . the advance mechanism includes a feed roller engaging the print substrate on a first surface of the print substrate for applying a driving force thereto and a pressure roller , being arranged opposite to the feed roller . the pressure roller has a textured outer surface which texture is in operation in rolling contact with a second surface of the print substrate . the texture of the outer surface is provided with a plurality of protrusions . the pressure roller diminishes print artifacts , which are related to an irregular crystallization of the hot melt ink .
