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.

A printer includes a nozzle from which a stream of printing fluid is electrostatically extracted and directed toward a printing surface. A diverter can selectively interrupt the stream of printing fluid so that at least some of the extracted printing fluid is not deposited on the printing surface. Another stream of printing fluid can be extracted from another nozzle in a different direction from the first. Respective diverters can selectively and independently interrupt each stream of printing fluid to control which portions of the extracted fluids are deposited over the printing surface. Diverted printing fluid can be collected and reused. The diverters allow for a more constant or uniform extraction field while permitting selective deposition of ink droplets similar to drop-on-demand printing schemes.

Techniques for operating an industrial printer include causing it to report data that indicates COO parameter values based on output sensors and/or component detection module configured to measure physical phenomena related to components of the printer referred to as COO parameters. The COO parameters values, which may include waste values, are derived and displayed in a graphical user interface dynamically on a real time basis. One or more graphical user interface is generated to present a one or more active areas to select the display of the COO parameter values in numeric and or graphical form or combinations thereof.

After specifying a processing target (target data), a requirement for printing is set. A simulation of a RIP process is performed on the target data under a plurality of printing conditions which are set in advance. Then, based on simulation results, a print-target identifying record is registered in a continuous printing list so as to satisfy the set requirement. After rearranging print-target identifying records registered in the continuous printing list, continuous printing is performed based on the continuous printing list.
