A continuous inkjet printer (10, 100) has an ink drop generator (12, 112a, 112b) to generate a stream of ink drops (24), deflection means (14, 16, 18, 20, 114, 115, 116, 118a, 118b, 120) to direct each drop of the stream of ink drops either to a gutter (28) or to one of a plurality of default print positions in a stroke direction (30) on a substrate (26, 126), and input means (22, 122) to receive an indication of an offset. The deflection means, in dependence upon the indication of the offset, direct drops that would otherwise be directed to default print positions to offset print positions on a substrate (26, 126), the offset print positions being displaced in the stroke direction 30 by the offset from the default print positions. The input means (22, 122) may also receive an indication of a print height scaling factor and the deflection means (14, 16, 18, 20, 114, 115, 116, 118a, 118b, 120), in dependence upon the indication of the print height scaling factor, direct drops that would otherwise be directed to default print positions to scaled print positions on a substrate (26, 126), the scaled print positions being displaced from the origin in the stroke direction (30) by displacements corresponding to displacements from the origin of the default print positions when scaled by the print height scaling factor.
