A printer has a printer body, a carriage for undergoing scanning movement over a print paper in a scanning direction, and a cassette removably connected to the printer body for storing print paper and having a code element indicative of photosensitive characteristics of the print paper. The print paper contains photosensitive microcapsules encapsulating a color developing material and a photo-curing material and has an image receiving layer for developing color by a reaction of the color developing material with the image receiving layer. The carriage has a light emitting element for emitting light of a preselected wavelength to which the photosensitive microcapsules are exposed to thereby form a latent image on the print paper. A photosensitive characteristics identifying mechanism is disposed on the carriage for reading the code element of the cassette to identify the photosensitive characteristics of the print paper. A light emission controller controls the intensity or the time period of emission of the light emitted by the light emitting element in accordance with the photosensitive characteristics of the print paper identified by the photosensitive characteristics identifying mechanism. A pressurizing mechanism applies mechanical pressure to the print paper after a latent image has been formed thereon to collapse the photosensitive microcapsules which were not exposed to the light emitted by the light emitting element and thereby develop the latent image by reaction of the color developing material in the photosensitive microcapsules with the image receiving layer.

A head for a printer and an image processing system is provided in which light emitted from light emitting elements formed on a substrate of the head does not leak from pinholes of a non-corresponding light emitting elements and does not interfere with light emitted by other light emitting elements, so that satisfactory printing can be carried out. An aperture has on opposite ends sandwiching portions and covers a substrate to sandwich a carriage. Concave portions are formed correspondence with light emitting elements. Pinholes are provided in a front wall and an insulating black coat is formed on the surfaces of the concave portions to prevent a short circuit. Light from the light emitting elements which does not pass through the pinholes is absorbed by the surfaces of the concave portions.

A plurality of waveguide elements are arranged to form an electromagnetic wave absorbing lattice in opposed relation to the advancing wave surface of the incident electromagnetic wave. Each waveguide element has a front opening on the lattice receptive of a part of the incident electromagnetic wave, a rear end portion spaced rearwardly from the front opening, and an inner peripheral surface portion extending between the front opening and the rear end portion to define a cavity effective to wave-guide the received electromagnetic wave. The inner peripheral surface portion has a given electric resistivity to effect absorption of the received electromagnetic wave during the wave-guiding thereof without substantial reflection thereof.
