A hardcopy printing mechanism and a greeting card feeder retrofit kit therefor, along with a retrofitting method are provided for printing images on a first-sized media, and on both surfaces a second-sized greeting card media without removing the first-sized media from its normal supply tray. The hardcopy device may be an electrophotographic or inkjet printer preferably equipped with a duplexer module which inverts media from a printed first surface to an opposing second surface for printing an image thereon. For a printer having an alignment surface, and a width adjuster to push the first-sized media against the alignment surface, the greeting card feeder includes a biasing member which pushes the card stock against the alignment surface. The retrofit kit includes a supply of pre-scored greeting card stock and a software program with a group of greeting card images for a consumer to select from to print store-bought quality greeting cards.

The invention provides a cellulosic fiber fabric ink jet transfer printing method. The cellulosic fiber fabric ink jet transfer printing method takes hydrophobic PET (polyethylene terephthalate) filmsor BOPP (biaxially-oriented polypropylene) films as base materials and comprises, firstly, in an ink jet mode, printing active dye ink onto the surface of the hydrophobic films which are processed with coatings, secondly, laminating and rolling the printed films with cellulosic fiber fabric to complete transfer of patterns, and lastly, performing steaming fixation and washing to complete a printing process. The cellulosic fiber fabric ink jet transfer printing method is high in dye transfer rate, good in color fastness of printed fabric and capable of ensuring reusability of the printed films.

Disclosed is a printing method whereby a glossy image free of running can be printed by an inkjet printer. An inkjet head (14) is caused to scan in the Y direction to print outline portions (32 and 33) on a medium (31). Next, immediately after the printing of the outline portions, a first UV irradiation means (15 or 16) disposed coaxially with the scanning axis of the inkjet head irradiates ink at the outline portions with UV light to harden the ink at the outline portions to prevent running. Next, the inkjet head prints a solid portion (34) between the outline portion (32) and the outline portion (33), and a second UV irradiation means (17) disposed forward in the scanning direction (X direction) of the medium (31) hardens the ink at the solid portion.

There is provided an inkjet printing apparatus which can perform stable ejection also in successive printing at high speed even in a case of performing printing in use of a print head provided with an ejection opening surface having hydrophilic properties. The inkjet printing apparatus comprises an inkjet print head wherein the control unit controls the print head such that, in a case where the ejection number of the ink ejected from the print head after removing the ink on the ejection opening surface by the ink removal unit is equal to or more than a threshold, a drive energy amount that is supplied for the preliminary ejection operation is larger than a drive energy amount that is supplied for the preliminary ejection operation in a case where the ejection number is less than the threshold.

Methods and systems of fabrication of high resolution, high-throughput electrochemical sensing circuits on a substrate. High resolution electrochemical sensing circuits are printed by an effective additive technique to the substrate. Optionally, post-print annealing converts electrochemically inactive printed graphene into one that is electrochemically active. The printing can be by aerosol jet printing, but is not necessarily limited thereto. An example is inkjet printing and then the post-print annealing. Ink formulation would be adjusted for effectiveness with inkjet printing. Optionally biorecognition agents can be covalently bonded to the printed graphene for the purpose of electrochemical biosensing. High throughput fabrication of high-resolution graphene circuits (feature sizes in the tens of microns <50 μm) for electrochemical biosensing is possible by chemical functionalization of the graphene surface with a biological agent.
