<p>A printing assembly includes a cylindrical sleeve having an inner surface and an outer surface. The inner surface defines a first channel and the outer surface defines a port fluidly connected to the first channel. The inner surface is configured for lateral movement along a nonporous surface in response to a first flow of pressurized air being directed into the first channel from the port. The inner surface is also configured to fixedly mate with the nonporous surface in response to removal of the flow.</p> |
