Abstract
Abstract The dot impact printer of the invention sets an optimum printing speed based on various factors, such as kanji or alphanumeric characters, and to set an optimum brake pulse and an optimum energizing energy corresponding to the set optimum printing speed. The printing mode is determined through a series of logic steps and optimum settings for the printing actions is selected according to the mode identified. Thus, in the invention, based on the print contents, a printing speed, an energizing period of time for the first dot, an energizing period of time for the following dots, a brake pulse width, a period of time till the generation of brake pulses and delay time, are changed.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
112 words
A method of setting a printing speed in a printer, comprising the steps of: identifying a desired speed; determining whether a paper being printed on is one-part paper; determining whether the printing is to be done in one pass; identifying a type of printing to be done; and setting an optimum printing speed and a second printing characteristic from a group consisting of an optimum brake pulse width and an optimum drive pulse width of a second and subsequent dots based on the type of printing, wherein the type of printing is comprised of a group of modes consisting of an ANK mode, a multi-part paper mode and a two-pass printing mode.
Claim 2
Independent Claim
112 words
A method of setting a printing speed in a printer, comprising the steps of: identifying a desired speed; determining whether a paper being printed on is one-part paper; determining whether the printing is to be done in one pass; identifying a type of printing to be done; and setting an optimum printing speed and a second printing characteristic from a group consisting of an optimum brake pulse width and an optimum drive pulse width of a second and subsequent dots based on the type of printing, wherein the type of printing is comprised of a group of modes consisting of an ANK mode, a multi-part paper mode and a two-pass printing mode.
Claim 3
Dependent Claim
20 words
The method as claimed in claim 1, wherein said multi-part paper mode also includes image printing and character ornamentation printing.
Claim 4
Dependent Claim
50 words
The method as claimed in claim 1, wherein when it is determined that the printing is to be done in more than one pass, the setting an optimum printing speed step is done based upon the two-pass printing mode and the step of identifying a type of printing is skipped.
Claim 5
Dependent Claim
74 words
The method as claimed in claim 1, wherein when it is determined the paper being printed on is a multi-part paper, the step as follows is executed: determining if printing is to be done in one pass, when yes, setting the optimum printing speed and the second printing characteristic appropriate to the multi-part paper mode and when no, setting the optimum printing speed and the second printing characteristic appropriate to the two-pass printing mode.
Claim 6
Dependent Claim
31 words
The method as claimed in claim 1, further comprising the step of determining whether a line contains mixed modes and setting the optimum printing speed and the second printing characteristic appropriately.
Claim 7
Dependent Claim
19 words
The method as claimed in claim 1, wherein said group of printing modes further includes a kanji printing mode.
Claim 8
Independent Claim
113 words
An apparatus for setting a printing speed in a printer, comprising: means for identifying a desired speed; means for determining whether a paper being printed on is one-part paper; means for determining whether the printing is to be done in one pass; means for identifying a type of printing to be done; and means for setting an optimum printing speed and a second printing characteristic from a group consisting of optimum brake pulse width and an optimum succeeding energizing pulse energy based on the type of printing, wherein the type of printing is comprised of a group of modes consisting of an ANK mode, a multi-part paper mode and a two-pass printing mode.
Claim 9
Independent Claim
113 words
An apparatus for setting a printing speed in a printer, comprising: means for identifying a desired speed; means for determining whether a paper being printed on is one-part paper; means for determining whether the printing is to be done in one pass; means for identifying a type of printing to be done; and means for setting an optimum printing speed and a second printing characteristic from a group consisting of optimum brake pulse width and an optimum succeeding energizing pulse energy based on the type of printing, wherein the type of printing is comprised of a group of modes consisting of an ANK mode, a multi-part paper mode and a two-pass printing mode.
Claim 10
Dependent Claim
20 words
The apparatus as claimed in claim 7, wherein said multi-part paper mode also includes image printing and character ornamentation printing.
Claim 11
Dependent Claim
43 words
The apparatus as claimed in claim 7, wherein when it is determined that the printing is to be done in more than one pass, the means for setting an optimum printing speed sets the optimum printing speed based upon the two-pass printing mode.
Claim 12
Dependent Claim
88 words
The apparatus as claimed in claim 7, wherein, when it is determined the paper being printed n is a multi-part paper the means for determining if printing is to be done in one pass determines printing is to be done in one pass and sets the optimum printing speed and the second printing characteristic appropriate to the multi-part paper mode and when it determines printing is not to be done in one pass, sets the optimum printing speed and the second printing characteristic appropriate to two-pass printing mode.
Claim 13
Dependent Claim
30 words
The apparatus as claimed in claim 7, further comprising means for determining whether a line contains mixed modes and setting the optimum printing speed and the second printing characteristic appropriately.
Claim 14
Dependent Claim
19 words
The apparatus as claimed in claim 7, wherein said group of printing modes further includes a kanji printing mode.
