Described herein are bioprinters comprising: one or more printer heads, wherein a printer head comprises a means for receiving and holding at least one cartridge, and wherein said cartridge comprises contents selected from one or more of: bio-ink and support material; a means for calibrating the position of at least one cartridge; and a means for dispensing the contents of at least one cartridge. Further described herein are methods for fabricating a tissue construct, comprising: a computer module receiving input of a visual representation of a desired tissue construct; a computer module generating a series of commands, wherein the commands are based on the visual representation and are readable by a bioprinter; a computer module providing the series of commands to a bioprinter; and the bioprinter depositing bio-ink and support material according to the commands to form a construct with a defined geometry.

In some examples, printing device temperature management may include ascertaining a print speed associated with a print job, and comparing the print speed to a print speed threshold. Printing device temperature management may further include actuating a power supply associated with a print bar at a start position of physical medium to be utilized for printing for the print job, or at or beyond a specified location along a path associated with traversal of the physical medium from the start position to a print zone to reduce an operational temperature associated with the print bar.

A printing apparatus for printing using a printhead including a plurality of nozzles, each configured to discharge ink, and a plurality of sensors, corresponding to the plurality of nozzles, for detecting a discharge state of ink from the plurality of nozzles, judges a discharge state. The apparatus prints, based on print data, an image by driving the printhead under a first drive condition to discharge the ink from the printhead to a first area, discharges ink to a second area different from the first area by driving the printhead, based on inspection data, under a second drive condition different from the first drive condition, and judges a discharge state of each nozzle by monitoring an output from each sensor at a timing of driving the printhead under the second drive condition.

A liquid ejecting apparatus includes a liquid ejecting portion configured to eject a liquid, a liquid collection device including a band-shaped member configured to come into contact with the liquid ejecting portion to wipe a liquid attached to the liquid ejecting portion, and a winding portion configured to wind up the band-shaped member, a temperature/humidity sensor configured to acquire temperature/humidity information related to a temperature and a humidity around the liquid collection device, and a control portion configured to cause the band-shaped member to come into contact with the liquid ejecting portion to wipe the liquid, and then cause the winding portion to wind up the band-shaped member. The control portion determines, based on the temperature/humidity information acquired by the temperature/humidity sensor, a winding length of the band-shaped member wound by the winding portion after the band-shaped member wipes the liquid.

An information processing device includes a storage portion storing a learned model trained by machine learning based on a data set in which temperature information, setting information, and countermeasure information are associated, a reception portion receiving the temperature information and the setting information at a time of ejecting ink by the printing head, and a processing portion deciding a countermeasure to be executed for condensation based on the received temperature information and setting information and the learned model.

A method of controlling a liquid ejecting apparatus that includes a liquid ejecting head having nozzles configured to eject a liquid, pressure chambers communicating with the nozzles, and drive elements configured to change the volume in the pressure chambers, and a drive-waveform generating circuit configured to generate a drive waveform for driving the drive elements to vibrate the liquid in the nozzles is provided. The method includes detecting a power-off operation for issuing an instruction for turning off an electric power of the liquid ejecting apparatus and vibrating the liquid by driving piezoelectric elements by the drive waveform in response to detecting the power-off operation by the detecting.

A temperature acquisition section (acquisition module) acquires a temperature of an environment in which a printer device is used. A printing condition acquisition section (acquisition module) acquires information relating to printing conditions of the printer device. A conveyance load estimation section (estimation module) estimates a conveyance load when a stepping motor (motor) provided in the printer device conveys a printing paper (print medium) based on the information acquired by the temperature acquisition section and the printing condition acquisition section. A current value setting section (setting module) sets a current value to be applied to the stepping motor based on the conveyance load estimated by the conveyance load estimation section. A motor control section (control module) controls the stepping motor by applying the current value set by the current value setting section to the stepping motor.

A liquid ejecting device includes a housing, an ejecting unit located in the housing that ejects liquid onto a medium, and a display unit that displays a recommended condition of an installation environment where a device is installed. The display unit displays, as the recommended condition, any of (a) a recommended temperature condition indicating a recommended temperature range, (b) a recommended relative humidity condition indicating a recommended relative humidity range, (c) a recommended absolute humidity condition indicating a recommended absolute humidity range, and (d) a recommended temperature condition and a recommended absolute humidity condition.

A recording apparatus that performs recording on a recording medium includes a low temperature marker that, depending on a change in temperature, changes a color state to a low-temperature first color state or to a low-temperature second color state different from the low-temperature first color state, and a surface on which the low temperature marker is disposed. The low temperature marker has a characteristic of indicating the low-temperature second color state when a temperature of the low temperature marker is higher than at least the low-temperature first threshold temperature after reached a temperature lower than or equal to a low-temperature first threshold temperature from an initial state indicating the low temperature first color state.
