In a printing system, an attached-time remaining sheet amount at detecting attachment of a sheet feed tray to the printing system is detected. And current remaining sheet amount at end of image printing is detected. Then, it is determined whether the attached-time sheet remaining amount is greater than a first threshold value. In response to determination that an attached-time sheet remaining amount is greater than a threshold value and the current remaining sheet amount is less than or equal to the threshold value, a controller executes an alert process corresponding to controlling a display to display an alert. In response to determination that the attached-time sheet remaining amount and the current remaining sheet amount are equal to or less than the first threshold value, the controller inhibits executing the alert process.

A printing apparatus includes: a plurality of sheet housing units; and a notification unit configured to, in a case where, in printing, a sheet is supplied from a first sheet housing unit included in the plurality of sheet housing units, make a notification of a message prompting that a user operation not be performed on a second sheet housing unit different from the first sheet housing unit. In a case where the second sheet housing unit is operated by a user, a path that the second sheet housing unit passes overlaps with at least a portion of a conveyance path of the sheet supplied from the first sheet housing unit.

A printing apparatus that prints images on a roll paper based on a job prints one or a plurality of image sets, each formed of a partition page image and a content image, on the roll paper based on a job in which partition information for inserting a partition page is set. In a case where the printing apparatus executes printing based on the job in which the partition information is set, control is performed to determine, based on a remaining amount of the roll paper loaded on the printing apparatus, a number of image sets that can be printed on the roll paper without interruption from among the image sets based on the job to print the determined number of image sets on the roll paper loaded on the printing apparatus.

In an image forming apparatus that the present invention is concerning to, rolled paper is conveyed in a forward conveyance direction for a predetermined period of time, when it is detected that an amount of the rolled paper rolled around a core pipe equals a predetermined amount or less. On the basis of the detection result, a CPU determines the rolled state of the rolled paper with respect to the core pipe and conveys the rolled paper in the forward conveyance direction or a reverse conveyance direction according to the rolled state.

A moving device includes a moving mechanism configured to support a plurality of printers and move positions of the plurality of printers, the plurality of printers being configured to execute printing processing for executing printing on roll paper, a take-out port through which a user takes out a receipt discharged from a first printer being one printer of the plurality of printers, and a first control unit configured to communicate with the plurality of printers and control the moving mechanism, wherein the first control unit includes a monitoring unit configured to monitor a state of each of the plurality of printers, and a movement instruction unit configured to cause the moving mechanism to move a position of the first printer to a take-out position at which the receipt is taken out through the take-out port, based on a monitoring result of the monitoring unit.
