Abstract
An envelope holder is described for feeding envelopes through a printer. It comprises a pocket formed from an upper and lower sheet joined together, a window portion of which is removed to allow printing of an envelope held in the pocket. The holder is improved in that the upper sheet has longitudinal edges that extend only a fraction of the length of the lower sheet portion that forms the pocket. That fraction is between about 30% and about 85% of the lower sheet length.
