1. A system for printing, comprising:
a liquid reservoir configured for holding a formulation, the formulation comprising a first amount of at least one depletable chemical agent, said first amount being substantially equal to or greater than a predetermined threshold value;
a replenishment reservoir configured for holding a second amount of said at least one depletable chemical agent;
detection means configured at least to identify a reduction in (i) said first amount of said depletable chemical agent below said predetermined threshold value and/or (ii) the functionability of said at least one depletable chemical agent,
wherein said reduction in the first amount of said depletable chemical agent occurs due to a side reaction of the depletable chemical agent with a contaminant; and
transfer means configured to transfer at least a portion of said second amount of the at least one depletable chemical agent from said replenishment reservoir to said liquid reservoir once said reduction has been identified.
