The present disclosure provides compositions and methods that employ the compositions for conducting pairwise sequencing and for generating concatemer template molecules for pairwise sequencing. The concatemers can be generated using a rolling circle amplification reaction which is conducted either on-support, or conducted in-solution and then distributed onto a support.

An example printing apparatus includes a reservoir to contain a printing agent. The printing apparatus further includes a recovery port to receive connection of a recovery vessel and to communicate flow of the printing agent from the reservoir to the recovery vessel during a recovery operation. The printing apparatus further includes a recovery pump to pump the printing agent from the reservoir through the recovery port to the recovery vessel during the recovery operation. The printing apparatus further includes a vacuum pump at the reservoir to reduce pressure in the reservoir to below atmospheric pressure during the recovery operation to draw unrecovered printing agent away from the recovery port when the recovery vessel is removed from the recovery port.
