A medium identification device identifies a type of a recording medium used for image formation. The medium identification device includes: a two-dimensional image sensor that captures an image of the recording medium; and an identifying unit that obtains a glossiness evaluation value indicating glossiness of the recording medium, a surface roughness evaluation value indicating surface roughness of the recording medium, and a coloring evaluation value indicating coloring of the recording medium, using image data of a specular reflection region reflecting specular reflection light from the recording medium and image data of a diffused reflection region reflecting diffused reflection light from the recording medium, the regions being in the image of the recording medium, and identifies the type of the recording medium by combining determination using the glossiness evaluation value, determination using the surface roughness evaluation value, and determination using the coloring evaluation value.

In a printer, a controller determines a type of print medium currently mounted in a mount portion, and acquires a first set of print data correlated with a first medium type and a second set of print data correlated with a second medium type. In a case that a print medium of the first medium type is mounted in the mount portion, a print portion prints a first print image based on the first set of print data, and thereafter prints a second print image based on the second set of print data. In a case that a print medium of the second medium type is mounted in the mount portion, the print portion prints the second print image based on the second set of print data, and thereafter prints the first print image based on the first set of print data.

A print condition setting method for setting a print condition in a printer includes: an ink type learning step of executing machine learning of an ink type discriminator using physical property information of ink and an ink type identifier; a medium type learning step of executing machine learning of a medium type discriminator using characteristic information of a medium and medium type identification information; and a print condition setting step of setting the print condition according to an ink type discriminated by the ink type discriminator and a medium type discriminated by the medium type discriminator.

A non-transitory computer-readable storage medium stores a set of program instructions including: (a) generating; (b) generating; (c) setting; and (d) displaying. The (a) generating generates a plurality of sets of print data corresponding to respective ones of a plurality of print labels used in an overlaid state. The (b) generating generates a plurality of sets of medium type information for respective ones of the plurality of print labels. Each medium type information indicates a type of a printing medium used for creating a corresponding print label. The (c) setting sets a layering order for the plurality of print labels. The (d) displaying displays a list of the plurality of sets of medium type information on a display. The plurality of sets of medium type information is arranged in the layering order for the plurality of print labels corresponding to respective ones of the plurality of sets of medium type information.

A non-transitory computer-readable storage medium stores computer-readable instructions for a terminal device including a processor. The computer-readable instructions, when executed by the processor, causes the terminal device to perform: generating a plurality of sets of label data for creating a plurality of print labels, each set of label data including print data and attribute specification information; acquiring a plurality of sets of medium type information for a plurality of printing devices, each set of medium type information indicating a type of a printing medium mounted in the corresponding printing device; determining a plurality of output destinations for the plurality of sets of print data from among the plurality of printing devices on the basis of the plurality of sets of label data and the plurality of sets of medium type information; and transmitting each of the plurality of sets of print data to the corresponding output destination.

An image forming apparatus includes a memory and a controller. The memory is configured to store information related to a recording medium type detected by a detector in the past. The controller is configured to control a feeder so as to prevent feeding of a recording medium from starting, when a printing operation is started in a first mode, in a case that a recording medium type set through a setting unit and a recording medium type discriminated based on the information stored in the memory do not match with each other.

An apparatus for determining a type of a recording medium is provided. A detection unit detects a characteristic value indicating a physical characteristic of a recording medium. A measurement unit measures a moisture content correlated with a moisture content of the recording medium. A determination unit determines the type of the recording medium based on the moisture content and the characteristic value. The determination unit may correct the characteristic value using the moisture content or correct a rule for determining the type of the recording medium using the moisture content unit, and determines the type of the recording medium in accordance with the corrected characteristic value or the corrected rule.

A printing apparatus to communicate with a terminal apparatus, includes a storing unit, an acquiring unit, a receiving unit, and a printing unit. The storing unit stores information for specifying first paper types selectable in the terminal apparatus. The terminal apparatus acquires the information from the printing apparatus and displays the first paper types as selection candidate paper types. The acquiring unit acquires a second paper type. The receiving unit receives a first paper type from the first paper types for printing of an image. The printing unit prints the image where the first paper type corresponding to second paper types is received and any of the second paper types corresponding to the first paper type is acquired, and does not print the image where the first paper type corresponding to second paper types is received and another second paper type different from the second paper types is acquired.

A server, which is capable of communicating with a printer or printers, each performing radio frequency identification (RFID) communication with a RFID tag, contains: a record unit configured to record, in a memory device, printer identification information for identifying a printer, tag identification information for identifying a RFID tag, and communication parameters with which the printer performs RFID communication, in an associated manner; a first obtaining unit configured to obtain, from a printer, printer identification information and tag identification information read by the printer; an identifying unit configured to identify communication parameters associated with the printer identification information and the tag identification information obtained by the first obtaining unit; and a first transmission unit configured to transmit the communication parameters identified by the identifying unit, to the printer.

A system and method for coating a lens (10) using a plurality of inkjet print bars (46) arranged in-line, includes generating, using at least one processor (54, 110) in communication with the plurality of inkjet print bars (46), at least one graphical user interface configured to facilitate the automation of the creation or selection of an image to be printed on a lens (10); generating a plurality of image layers based on the lens (10) geometry, target product, and number of print bars (46); and controlling, using the at least one processor (54, 110), at least two of the plurality of inkjet print bars (46) to print the image on the lens (10), such that each of the at least two inkjet print bars (46) prints at least one image layer of the plurality of image layers.
