Abstract
Disclosed is an electronic apparatus provided with a printer for printing characters on a recording material with at least two different colors of ink. The apparatus has means for setting a special printing mode. In the special printing mode, data are printed with ink in the first color while printing a background pattern with ink in the second color thereby forming a print with a background pattern.
Claims11
An ink jet printer comprising:
- a first ink jet nozzle for jetting ink of a first color;
- a second ink jet nozzle for jetting ink in a second color different from said first color,
- first memory means associated with said first ink jet nozzle for storing information to be printed by said first ink jet nozzle,
- second memory means associated with said second ink jet nozzle for storing information to be printed by said second ink jet nozzle, and
- control means for selectively providing to said second ink jet nozzle and said first ink jet nozzle information stored in said respective memory means for printing a background pattern with one said ink jet nozzle and characters that appear to be superimposed on the background pattern with the other said ink jet nozzle.

An ink jet printer comprising:
- a first ink jet nozzle for jetting ink of a first color;
- a second ink jet nozzle for jetting ink of a second color;
- first memory means associated with said first ink jet nozzle for storing information to be printed by said first ink jet nozzle;
- second memory means associated with said second ink jet nozzle for storing information to be printed by said second ink jet nozzle according to contents stored therein;
- and
- generating means for generating a dot pattern with said ink jet nozzles by selectively providing to said second ink jet nozzle and said first ink jet nozzle information stored in said respective memory means for printing a background pattern with one said ink jet nozzle and characters with the other said ink jet nozzle, wherein said characters have a greater dot density than said background pattern.
3 more elements
Electronic apparatus provided with a printer, said apparatus comprising:
- a first ink jet nozzle for jetting ink in a first color,
- a second ink jet nozzle for jetting ink in a second color different from said first color,
- a first memory for transmitting character data to said first ink jet nozzle,
- a second memory for transmitting to said second ink jet nozzle data which form a background pattern for said character data,
- selection means for selecting the use of said second ink jet nozzle and memory together with said first ink jet nozzle and memory, and
- a carriage having said first and second ink jet nozzles mounted therein, and means for moving said carriage to cause said first and second nozzles to scan a recording medium,
- wherein when said second ink jet nozzle and memory are selected by said selection means, said first and second memories operate in correspondence with movement of said carriage and said first and second ink jet nozzles are sequentially operated to form characters with a background pattern.
