Abstract
Abstract A system for first justifying a text line according to a system minimum escapement unit, and then rejustifying the line according to a minimum escapement unit for a printer which is to be utilized in printing the line. The first justification of the line is in a normal manner. That is, any residue is divided by the number of word spaces on the line to obtain a quotient and any remainder. The extent of word space expansion is then the value of the quotient plus the remainder until exhausted. Rejustification for the printer being utilized is accomplished by dividing each system justified word space size by the printer minimum escapement unit to obtain a new quotient and remainder. Each system justified word space is then converted to a value including the obtained quotient for each space, and the remainders for all spaces are accumulated for adding to the first word space.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
117 words
A system for justifying text lines made up of characters, words, and spaces, and to be printed with a printer having a minimum escapement unit differing from a minimum escapement unit for said system, said system comprising: (a) means for scanning said line for determining a size of each word space in a line to be printed; (b) means for dividing each determined word space size by said printer minimum escapement unit to obtain a quotient and any remainder; (c) means for converting each determined word space size to a size including said quotient and accumulating said any remainder; and (d) means for adding said accumulated remainder to a size of a word space on said line.
Claim 2
Independent Claim
117 words
A system for justifying text lines made up of characters, words, and spaces, and to be printed with a printer having a minimum escapement unit differing from a minimum escapement unit for said system, said system comprising: (a) means for scanning said line for determining a size of each word space in a line to be printed; (b) means for dividing each determined word space size by said printer minimum escapement unit to obtain a quotient and any remainder; (c) means for converting each determined word space size to a size including said quotient and accumulating said any remainder; and (d) means for adding said accumulated remainder to a size of a word space on said line.
Claim 3
Dependent Claim
30 words
A system according to claim 1 wherein said converting means includes means for converting the first word space encountered by said scanning means to a size including said accumulated remainder.
Claim 4
Dependent Claim
103 words
A system according to claim 1 wherein said scanning means includes means for initially scanning said line to determine the number of word spaces in said line and the size of any residue in system minimum escapement units, said word spaces being a number of system minimum escapement units in size; (a) means for dividing said residue size by said number of word spaces to obtain a quotient and a remainder in system minimum escapement units; and (b) means for adding said quotient, and one escapement unit from said remainder until exhausted, to each word space on said line to justify and line.
Claim 5
Dependent Claim
29 words
A system according to claim 3 wherein said means for adding includes means for adding one escapement unit from said remainder beginning in the direction of said initial scanning.
Claim 6
Dependent Claim
21 words
A system according to claim 4 including means for alternating the end of succeeding lines at which scanning is to begin.
Claim 7
Independent Claim
101 words
A method of justifying text lines made up of characters, words, and spaces for printing with a system having a printer having a minimum escapement unit differing from a minimum escapement unit for said system; said method comprising: (a) scanning a system justified line to determine word space sizes in said line; (b) dividing each word space size by said printer minimum escapement unit to obtain a quotient and any remainder; (c) converting each space size so divided to a size including said quotient; (d) accumulating all remainders; (e) adding an accumulation of all remainders to a converted word space size.
Claim 8
Independent Claim
101 words
A method of justifying text lines made up of characters, words, and spaces for printing with a system having a printer having a minimum escapement unit differing from a minimum escapement unit for said system; said method comprising: (a) scanning a system justified line to determine word space sizes in said line; (b) dividing each word space size by said printer minimum escapement unit to obtain a quotient and any remainder; (c) converting each space size so divided to a size including said quotient; (d) accumulating all remainders; (e) adding an accumulation of all remainders to a converted word space size.
Claim 9
Dependent Claim
24 words
A method according to claim 6 including converting the first word space encountered during scanning to a size including said accumulation of all remainders.
Claim 10
Dependent Claim
94 words
A method according to claim 7 including: (a) initially scanning said line to determine the number of word spaces in said line and the size of any residue in system minimum escapement units, said word spaces being a number of system minimum escapement units in size; (b) dividing said residue size by said number of word spaces to obtain a quotient and any remainder in system minimum escapement units; and (c) adding said quotient, and one escapement unit from said remainder until exhausted, to each word space on said line to justify said line.
Claim 11
Dependent Claim
22 words
A method according to claim 8 including adding one escapement unit from said remainder beginning in the direction of said initial scanning.
Claim 12
Dependent Claim
19 words
A method according to claim 9 including alternating the end of succeeding lines at which scanning is to begin.
