Examples disclosed herein relate to detecting an error condition blocking an operational mode of a device, determining whether the operational mode will cause a loss of at least one data element, and in response to determining that the operational mode will cause a loss of at least one data element, storing a copy of the at least one data element and causing the device to enter the operational mode.

An image forming apparatus, includes: an image generator; a motion sensor; a login-logout processor; a display; a console; a memory; an on-hold setting receiver that receives a setting to either hold or cancel a set value not completely entered, when the motion sensor is not able to detect the user; and a controller that controls the image generator, the motion sensor, the login-logout processor, the display, the console, the memory, and the on-hold setting receiver. The controller causes the memory to store the set value not completely entered and switches a setting screen if the on-hold setting receiver is set to hold the setting not completely entered when the motion sensor is not able to detect the user while the display displays the setting screen, and cancels the set value not completely entered and switches the setting screen if the on-hold setting receiver is set to cancel the setting not completely entered.

A processing system includes a service provider, such as a printing device, that receives requests to process tasks or jobs from service requesters. At times, the service provider will not be available for processing and will generate deferral responses to the service requesters. The deferral responses include a condition to be met before processing requests can be resent from the service requesters. After the condition is met, the processing requests are resent to the service provider to be fulfilled.

There is disclosed a device, method and program, wherein the method comprises detecting a power increase, during which power usage increases by at least a threshold amount over an expected power usage during movement of a printer carriage over a print medium along a scan axis. The increase method further comprises detecting a location of the printer carriage at a time of the detected power usage increase and determining, based on the detected location of the printer carriage, whether the print medium is damaged.

There are provided a printing section that performs printing on a medium; a control section that controls drive of the printing section; a power supply connector that supplies electric power to the control section; a first receptacle connector that is electrically coupled to a first external device; and a second receptacle connector that is electrically coupled to a second external device, a plug of a USB-Type-C cable is configured to be physically inserted into the second receptacle connector, the plug is configured not to be physically inserted into the power supply connector, an insertion port of the first receptacle connector is arranged along a first connector surface, and an insertion port of the second receptacle connector is arranged along a second connector surface.

An estimated temperature adjustment time, the number of times of temperature adjustments, and so on for printing jobs in a current print sequence are displayed together with an estimated print time, and the print sequence can be changed so as to decrease the number of times of temperature adjustments.

Upon receiving a resumption notification from a system controller, a printer driver determines whether a power supply to a printer apparatus has stopped/resumed after a previous transition instruction to a sleep state was transmitted to the printer apparatus. If stop/resumption is not performed, an initialization negotiation processing performed to the printer apparatus when stop/resumption is not performed.

The printer (10) of the present disclosure is a printer connectable to a network (30) and an information processing terminal (20), including a control section (15) configured to: when obtaining data in accordance with the network class from the information processing terminal (20), extract a first frame based on a first communication standard used for communications between the printer (10) and the network (30), from the data; when determining that destination information included in the first frame specifies the printer (10), extract and interpret print information included in the first frame; and when determining that the destination information included in the first frame does not specify the printer (10), forward the first frame to the network (30).

A power management technique for a printer includes detecting a change in a state of operation of a printing device. The amount of power available to operate all functions of the printing device is calculated. Next, power is delivered to specified functions of the printing device based on the calculated amount of power available, wherein the specified functions are a subset of all functions of the printing device. Then, it is determined whether the specified functions operate correctly.

An information processing apparatus capable of changing a state of power supply to respective parts of the apparatus with less user operation. When a sleep recovery button is depressed in a power saving mode, a button depression time is measured, and whether a length of the measure depression time exceeds a threshold value is determined. If the depression time exceeds the threshold value, a normal power mode is selected as power mode after transition. If the depression time does not exceed the threshold value, another power saving mode is selected as power mode after transition. According to the selected power mode, a state of power supply to respective parts of the apparatus is changed.
