The present disclosure provides a printing device comprising a sheet buffer including a paper path having a plurality of nip pairs for selectively receiving and releasing a plurality of printer sheets. The plurality of nip pairs include a fixed load nip pair, a fixed unload nip pair, and at least another intermediate fixed nip pair therebetween. In a first operation each subsequent sheet of the plurality of sheets is shingled over a previous sheet wherein the plurality of sheets can be stopped in the intermediate nip pair or pairs. Individual sheets of the plurality of sheets can be advanced to the unload nip pair sequentially in a second operation whereupon the individual sheets are successively unloaded as needed in a first in first out order.
