Abstract From the Canadian patent

An ink jet printer and a method of printing are disclosed in which a plurality of sheets of copy paper are simultaneously supplied to a paper supporting drum prior to printing and simultaneously removed from the drum after printing. One print head or, alternately multiple print, heads may be utilized during the printing operation. The time required for loading copy paper onto the drum and removing it from the drum and also the time required for the print head or heads to complete printing on all of the sheets of copy paper are therefore both reduced thus, permitting attainment of higher copy rates.
