Claims
- 1. A method for printing a high density sequence of characters from a predetermined character set, said method comprising the steps of:
- for a character sequence which includes M characters per inch;
- printing within said character sequence each of a small number of preselected characters from said predetermined character set within a 7.times.4 pel-rectanular character matrix having a width eaual to 1/M inches such that a printed portion of each of said small number of preselected characters has a total width equal to 1/M inches; and
- printing selected remaining characters within said character sequence from said predetermined character set such that a printed portion of said selected remaining characters has a total width of 31/2 pels.
- 2. The method for printing a high density sequence of characters according to claim 1, further including the step of printing each symmetric character from said predetermined character set within a rectangular character matrix having a width equal to an integer number of pels.
- 3. The method for printing a high density sequence of characters according to claim 1, further including the step of printing each nonsymmetric character from said predetermined character set within a rectangular character matrix having a width equal to a noninteger number of pels.
- 4. The method for printing a high density sequence of characters according to claim 1, further including the step of printing each character from said predetermined character set with a pel addressability that is a factor of two or greater than normal pel density.
- 5. A system for printing a high density sequence which includes M characters per inch from a predetermined character set, said system comprising:
- a plurality of print wires for selectively printing a matrix of dots; and
- control means coupled to said plurality print wires for printing within said character sequence each of a small number of preselected characters from said predetermined character set within a 7.times.4 pel rectangular character matrix having a width equal to 1/M inches such that a printed portion of each of said small number of preselected characters has a total width equal to 1/M inches and for printing selected remaining characters within said character sequence from said predetermined character set such that a printed portion of said selected remaining characters has a total width of 31/2 pels.
- 6. The system according to claim 5, wherein said control means prints each symmetric character from said predetermined character set within a rectangular character matrix having a width equal to an integer number of pels.
- 7. The system according to claim 5, wherein said control means prints each nonsymmetric character from said predetermined character set within a rectangular character matrix having a width equal to a noninteger number of pels.
- 8. The system according to claim 5, wherein said control means prints each character from said predetermined character set with a pel addressability that is a factor of two or greater than normal pel density.
- 9. A system for printing a high density sequence of M characters per inch utilizing a pel density of four M pels per inch, said system comprising:
- a plurality of print wires for selectively printing a matrix of dots;
- means coupled to said plurality of print wires for printing each of a small number of preselected characters from said predetermined character set within a character matrix having a width equal to four pels; and
- means coupled to said plurality of print wires for printing selected remaining characters from said predetermined character set within a character matrix having a width of three and one-half pels.
