A fluid pathway is configured to selectively fluidically couple a printing fluid supply container to a printhead. The serving base station transmits in a neighbor list an estimated timing error 417 between the serving base station and a target base station. In one embodiment, at least one angiogram frame is received and preprocessed. A quote profile and an author profile may be generated providing information about a quote and an author respectively. The vernier movement can also be used to sense collisions and other positioning errors and actuation of the drive for the vertical support can be controlled accordingly. The limiter is slidably inserted through the first end and the second end is affixed to a depressable plunger for expelling the substance from the container.
