Electronic equipment with a printer

Claim 2

Electronic equipment having a printer, comprising: numeric keys for providing graph data; key means for manually selecting one of a first print mode in which the graph data is printed at a first print density and a second print mode in which the graph data is printed at a second print density higher than the first print density; and print means including a dot print element for reciprocating along a line relative to a recording medium to print dots thereon, wherein said dot print element prints when moving in one direction when the first print mode is selected and prints when moving in both directions when the second mode is selected, so as approximately to double the number of dots used to print the graph data in the second print mode.

Claim 3

Electronic equipment according to claim 1; further comprising: means for selectively feeding the recording medium in a direction substantially perpendicular to the line of reciprocation of said dot print element at one of first and second pitches, the second pitch being shorter than the first pitch; and means for feeding the recording medium at the first pitch when the first print mode is selected and at the second pitch when the second print mode is selected.

Claim 4

Electronic equipment according to claim 1; wherein said print means includes an ink jet nozzle driver for forming dots of a substantially constant size in both print modes.

Claim 5

Electronic equipment having a printer, comprising: numeric keys for providing graph data; key means for manually selecting one of a first print mode in which the graph data is printed at a first print density and a second print mode in which the graph data is printed at a second print density higher than the first print density; print means including a dot print element for reciprocating along a line relative to a recording medium to print dots thereon; means for selectively feeding the recording medium in a direction substantially perpendicular to the line of reciprocation of said dot print element at a pitch selected from one of a reference pitch and a second pitch substantially equal to one-half of the reference pitch, the reference pitch being substantially equal to the dot size; and means for controlling said print means so that said dot print element prints when moving in one direction and the recording medium is fed at the reference pitch when the first print mode is selected and so that said dot print element prints when moving in both directions and the recording medium is fed at the second pitch when the second print mode is selected.

Claim 6

Electronic equipment having a printer, comprising: numeric keys for providing graph data; key means for manually selecting one of a first print mode in which the graph data is printed at a first print density and a second print mode in which the graph data is printed at a second print density higher than the first print density; print means including a dot print element for reciprocating along a line relative to a recording medium to print dots thereon; means for selectively feeding the recording medium in a direction substantially perpendicular to the line of reciprocation of said dot print element at a pitch selected from one of a reference pitch and a second pitch substantially equal to one-half of the reference pitch, the reference pitch being substantially equal to the dot size; and means for controlling said print means so that said dot print element prints when moving in one direction and the recording medium is fed at the reference pitch when the first print mode is selected and so that said dot print element prints when moving in both directions and the recording medium is fed at the second pitch when the second print mode is selected.

Claim 7

Electronic equipment according to claim 5; wherein said print means includes an ink jet nozzle driver for forming dots of a substantially constant size in both print modes.
