ABSTRACT:
A printer comprises a scan axis (14) arranged to receive at least one pen (10), each pen comprising an array of ink ejection elements (20,22) adapted to print a swath on a printing medium. Printer control circuitry is responsive to selection of a multi-pass print mode, to cause a printing medium advance mechanism to incrementally advance the printing medium (26) past the pens in a printing advance direction (PAD) between the printing of a first swath and a second swath. Thus, a first group of ink ejection elements dispenses ink in a swath along respective rows on the printing medium with at least one other group of corresponding ink ejection elements dispensing ink along those rows in subsequent swaths. The printer control circuitry is further arranged to cause the first group of ink ejection elements to dispense proportionally more ink per swath than the other groups of ink ejection elements in subsequent swaths.
