Abstract
Abstract A bar code printer is used for the printing of symbol guards (25) to be printed on both sides of a bar code pattern (23) leaving fixed margins (24), simultaneously with printing of the bar code pattern (23) formed with the combination of wide lines and narrow lines having been standardized previously. Even if wrinkles on a thermal transcription ink ribbon occur in the vicinity of symbol guards (25) provided on both sides of the bar code pattern (23), the wrinkles do not occur in the bar code printing region; it is therefore possible to perform high quality bar code printing with the bar code printer.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
59 words
A bar code printing method wherein symbol guards are provided in the height direction and on both sides of said bar code pattern formed with the combination of wide lines and narrow lines having been standardized previously leaving fixed margins between them together with a bar code pattern with a thermal print head using a thermal transcription ink ribbon.
Claim 2
Dependent Claim
59 words
A bar code printing method wherein symbol guards are provided in the height direction and on both sides of said bar code pattern formed with the combination of wide lines and narrow lines having been standardized previously leaving fixed margins between them together with a bar code pattern with a thermal print head using a thermal transcription ink ribbon.
Claim 3
Dependent Claim
26 words
A bar code printing method according to claim 1 wherein the height of a symbol guard is the same as that of a bar code pattern.
Claim 4
Dependent Claim
99 words
A bar code printing method for printing said bar code pattern together with symbol guards with a thermal print head using a thermal transcription ink ribbon wherein the start of printing of said bar code pattern is later than the start of printing of said symbol guards to be printed on both sides of said bar code pattern formed with the combination of wide lines and narrow lines having been standardized previously leaving margins of fixed width between them; the start of printing of said symbol guards being prior to the start of printing of said bar code pattern.
Claim 5
Dependent Claim
99 words
A bar code printing method for printing said bar code pattern together with symbol guards with a thermal print head using a thermal transcription ink ribbon wherein the start of printing of said bar code pattern is later than the start of printing of said symbol guards to be printed on both sides of said bar code pattern formed with the combination of wide lines and narrow lines having been standardized previously leaving margins of fixed width between them; the start of printing of said symbol guards being prior to the start of printing of said bar code pattern.
Claim 6
Dependent Claim
42 words
A bar code printing method according to claim 1, claim 2 or claim 3 wherein a symbol guard is formed with one or ones selected from a full line, a broken line, characters, patterns, a frame, etc. surrounding the bar code pattern.
Claim 7
Dependent Claim
31 words
A bar code printing method according to claim 1, claim 2 or claim 4 wherein the height of a symbol guard is made higher than that of the bar code pattern.
Claim 8
Dependent Claim
31 words
A bar code printing method according to claim 1 or claim 3 wherein a symbol guard is formed with a frame surrounding the whole or part of the bar code pattern.
Claim 9
Dependent Claim
88 words
A bar code printing method for printing said bar code pattern together with symbol guards wherein the start of printing of said bar code pattern is later than the start of printing of said symbol guards to be printed on both sides of the bar code pattern formed with the combination of wide lines and narrow lines having been standardized previously leaving margins of fixed width between them; the start of printing of said symbol guards being prior to the start of printing of said bar code pattern.
Claim 10
Dependent Claim
88 words
A bar code printing method for printing said bar code pattern together with symbol guards wherein the start of printing of said bar code pattern is later than the start of printing of said symbol guards to be printed on both sides of the bar code pattern formed with the combination of wide lines and narrow lines having been standardized previously leaving margins of fixed width between them; the start of printing of said symbol guards being prior to the start of printing of said bar code pattern.
Claim 11
Dependent Claim
106 words
A bar code printer comprising: a bar code storage means for storing a variety of bar code patterns; a bar code designating means for designating a bar code pattern to be printed; a symbol guard setting means for setting symbol guards on both sides of the designated bar code pattern leaving fixed margins; an image buffer for storing a bar code pattern formed with said bar code designating means and said symbol guard setting means; a thermal print head for printing the contents of the image buffer; a thermal transcription ink ribbon to be interposed between the thermal print head and a sheet of recording paper.
