An image forming apparatus includes a roller, a heater configured to heat the roller, an endless belt, a nip forming member, a supply roller configured to supply a sheet, and a controller. The sheet is nipped between the endless belt and the roller. The endless belt is nipped between the nip forming member and the roller such that a nip portion is formed. The controller is configured to supply a plurality of first kind of sheets by the supply roller at a first interval when the plurality of first kind of sheets are sequentially conveyed and supply a plurality of second kind of sheets by the supply roller at a second interval greater than the first interval when the plurality of second kind of sheets belonging to a kind in which curl occurs more frequently than the plurality of first kind of sheets are sequentially conveyed.

A producing method for a print by a printing system including a printing device that is manually moved with respect to a medium to perform printing on the medium, the producing method including the printing system determining whether a print plan size of a print image is a one-pass printable size, which is a size printable in one pass by the printing device, and, when it is determined that the print plan size is not the one-pass printable size, the printing device printing the print image in the one pass.

A controller of an editing device executes displaying, on a display unit, an input area image corresponding to an input area in which the characters are arranged by overlapping the input area image on a medium image showing the printing medium, changing a size of the input area image displayed in the displaying, using first method or second method, according to a first instruction for changing the size of the input area, the first method being changing the size of the input area by setting a portion of the medium image corresponding to the non-light-transmitting area as a maximum range, the second method being changing the size of the input area by setting the entire medium image as a maximum range, and switching between the first method and the second method as a first switching.

An information processing apparatus, which communicates with an image forming apparatus and a reader, including: a display; and a controller configured to: obtain read image data output from the reader; determine an error of the read image data based on the read image data and reference data; cancel image forming operation of the image forming apparatus in a case where the error is determined in succession a predetermined number of times; cancel reading operation of the reader in the case where the error is determined in succession the predetermined number of times; notify, on the display, the cancellation of the image forming operation and the reading operation in the case where the error is determined in succession the predetermined number of times; and receive a user's instruction information about the predetermined number of times.

An image forming apparatus includes: an image forming unit configured to form an image on a sheet of perforated paper which has been perforated; an input unit configured to receive first information and second information; and a processor configured to display an alarm display without performing sheet-passing of the sheet of perforated paper. The first information is information concerning the sheet of perforated paper on which an image is to be formed by the image forming unit and wherein the second information is information concerning whether to perform automatic double-sided printing on the sheet of perforated paper or not. The processor is configured to display the alarm display in a case where the automatic double-sided printing is instructed and it is determined that the sheet of perforated paper has a cut-off portion.

An image forming apparatus on which a replaceable container storing a recording material is mounted includes an image forming unit configured to form an image using the recording material, a determination unit configured to determine whether the container satisfies a predetermined condition, an acquisition unit configured to acquire an amount of the recording material used for image formation in a predetermined period and stored in the container determined as a container that satisfies the predetermined condition, a memory configured to accumulate information indicating the amount of the recording material acquired by the acquisition unit, and a prediction unit configured to predict a number of days about replacement of the container, based on the information indicating the amount of the recording material and accumulated in the memory.

An information processing apparatus includes at least one processor configured to: acquire physical-property-value information of a recording medium; using information regarding a printing machine, perform an evaluation as to whether there is a possibility that the recording medium causes trouble for printing by the printing machine, the evaluation being performed with respect to at least one printing performance indicator based on the physical-property-value information; and output a result of the evaluation to a display device.

A label issuing system includes a label issuing apparatus and a label printer. The label issuing apparatus includes a printer interface and a processor. The processor is configured to generate print data for an image including a first region with first information and a second region with a first code symbol and a second code symbol each representing the first information but being of different sizes. The processor controls the printer interface to transmit the print data to the label printer. The label printer is connectable to the printer interface and configured to print the image on a label based on the print data received through the printer interface symbol.

An image forming apparatus on which a replaceable container storing a recording material is mounted includes an image forming unit configured to form an image using the recording material, a determination unit configured to determine whether the container satisfies a predetermined condition, an acquisition unit configured to acquire an amount of the recording material used for image formation in a predetermined period and stored in the container determined as a container that satisfies the predetermined condition, a memory configured to accumulate information indicating the amount of the recording material acquired by the acquisition unit, and a prediction unit configured to predict a number of days about replacement of the container, based on the information indicating the amount of the recording material and accumulated in the memory.
