Abstract (en)

[origin: ES485757A1] Disclosed is a multi speed ink jet printer in which alternate vertical scans of the ink stream may be omitted or alternate dots horizontally may be omitted or a combination of the two. In the alternate vertical scan omit mode, a factor of two increases in the speed of printing may be obtained, the same being true of a horizontal row dot omission. Moreover, a combination of the two permits up to a four times speed increase. In essence, while the rate of the ink stream remains constant, the predetermined maximum number of dots (picture elements) in a character box is decreased (resolution decreased) to permit an increase in the speed of printing.
