Abstract

A printing device for printing labels comprises a memory for storing one or more character sets, each character set including at least a principle character and an additional character which is associated with the principle character; user input means having character selection keys for selecting a character set to define an image to be printed by the printing device; and a controller for accessing characters from the memory to be displayed and printed which correspond to characters selected at the user input means. The first actuation of a character selection key selects the principle character in the selected character set and a subsequent activation of the character selection key in a predetermined time frame selects the associated additional character.

Claims

user input means having character selection keys for selecting a character set to define an image to be printed by the printing device;

a print head having a column of printing elements, each of which is selectively activatable to print the defined image on a column-by-column basis; and

a controller for accessing characters from the memory to be displayed and printed which correspond to characters selected at the user input means;

wherein the first actuation of a character selection key selects the principal character in the selected character set and the second activation of the character selection key in a predetermined time frame selects the at least one additional character in the selected character set.

2. A printing device according to claim 1, wherein at least two additional characters are associated with the principal character and further subsequent activations of the character selection key within the predetermined time frame from the previous activation selects further additional characters.

3. A printing device according to claim 2, wherein different character sets comprise additional characters having different accents and further additional characters having different accents and a different number of further additional characters.

4. A printing device according to claim 1, further comprising a display configured to display selected characters.

5. A printing device according to claim 4, wherein the display is further configured, prior to and until a subsequent activation of a character selection key in a predetermined time frame, to temporarily display the character which would be selected if the subsequent activation did not occur.
