摘要： In some examples, the disclosure describes a printing device that includes a processor resource, and a non-transitory memory resource storing machine-readable instructions stored thereon that, when executed, cause the processor resource to: estimate a drying time of a print medium received at an output roller from a print zone, activate the output roller at a first speed to move the print medium to an output tray in response to receiving the print medium from the print zone, alter a direction of the output roller to move the print medium toward a turn roller at a second speed based on the drying time of the print medium, and stop the output roller to prevent the print medium from reaching the turn roller for a period of time based on the drying time.

摘要： An example support for a fluid container is described, comprising a bracket comprising a U-shaped cross section and a strain gauge attached on a web of the U-shaped cross section of the bracket, between a mounting portion for attaching the bracket to a printing apparatus and a bearing portion for attaching a fluid container to the bracket. An example method for determining the amount of fluid in a container is also described, comprising measuring with a strain gauge a strain occurring at the web of a U-shaped bracket, the U-shaped bracket having a wing for attachment to a printing apparatus and a wing for carrying a fluid container; and determining the amount of fluid in the fluid container based on the measured strain.

摘要： According to examples, an apparatus may include a chassis having an interior region and a first printing fluid reservoir arranged within the interior region of the chassis. The chassis may fix the first printing fluid reservoir relative to a second printing fluid reservoir. The apparatus may also include a bottle seat that may define a charging port in fluidic communication to the first printing fluid reservoir to convey refill printing fluid received at the charging port to the first printing fluid reservoir. A fluidic interface may be arranged on the chassis and fluidically coupled to the first printing fluid reservoir to convey the printing fluid outside the chassis to a print head.

摘要： In some examples, a device for pulse width modulation value calculations can include a non-transitory machine readable medium storing instructions executable by a processing resource to: determine when a start temperature of a heated pressure roller is above a threshold temperature, calculate a pulse width modulation (PWM) value for the heated pressure roller based on a set point for the heated pressure roller and a difference between the start temperature and the threshold temperature, and apply the calculated PWM value as a seeding value for the heated pressure roller when the start temperature is above the threshold temperature.
