An envelope feeding and printing assembly providing for the individual, lengthwise feeding of envelopes (7) and enabling printing thereon while said envelopes (7) are in motion, including a plurality (77) of print heads (81,83,85,87,89, & 92) and a platen (75) for imprinting the envelopes (7), an envelope storage bin (5) for holding a stack of envelopes prior to printing and having a gate (32) with a driven feed roller (35) and a control surface (45) defining an envelope nip (51) leading from the bin (5) to the print head array (77), transport rollers (61,67) to carry envelopes from the gate (32) to the platen (75), timing control means (111) to produce timing signals corresponding to the speed of the transport rollers (61,67), an envelope position sensor to sense the leading and following edges of envelopes passing through said transport rollers (61,67) and to produce control signals corresponding to envelope position, and a controller (121) to receive the timing and control signals and to control the feed roller (35) and to control the "start time" and speed of printing of the print heads (77), so that envelopes may be printed seriatim and lengthwise while continuously moving. The print heads (81,83,85,87,89 & 92) may be offset longitudinally to permit closer line spacing and "start times" of individual lines adjusted accordingly.
