Abstract
Abstract The invention relates to a method of operating a microballistic printer in which successive projectiles are fired against a platen to print successive dots and the gun is moved along a path to form characters from the successive dots. In order to prevent collisions between successively fired projectiles, the gun is positioned away from a plane extending normal to and outside of the printing area of the platen. Successive movements of the gun are in a direction away from this plane toward the gun.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
116 words
A method of operating a microballistic printer having a gun for firing projectiles in succession across a space to a platen having a printing area to form characters on a medium placed against the platen, including the steps of positioning the gun spaced from a plane normal to and outside of a boundary of the printing area of the platen and moving the gun to form characters in successive steps, each moving step being in a direction toward the gun, whereby every subsequently fired projectile prints in a direction away from a previously fired projectile rebounding from the platen, thereby avoiding collision of a subsequently fired projectile with a previously fired projectile rebounding from the platen.
Claim 2
Independent Claim
116 words
A method of operating a microballistic printer having a gun for firing projectiles in succession across a space to a platen having a printing area to form characters on a medium placed against the platen, including the steps of positioning the gun spaced from a plane normal to and outside of a boundary of the printing area of the platen and moving the gun to form characters in successive steps, each moving step being in a direction toward the gun, whereby every subsequently fired projectile prints in a direction away from a previously fired projectile rebounding from the platen, thereby avoiding collision of a subsequently fired projectile with a previously fired projectile rebounding from the platen.
Claim 3
Independent Claim
98 words
A method of operating a microballistic printer having a gun for firing projectiles in succession across a space to a platen having a printing area to form characters on a medium placed against the platen, including the steps of positioning the gun spaced above a horizontal plane normal to and above the boundary of said printing area and moving the gun to form characters in successive steps, each moving step in a vertical direction being from bottom to top, whereby every subsequently fired projectile prints in a direction away from a previously fired projectile rebounding from the platen.
Claim 4
Independent Claim
98 words
A method of operating a microballistic printer having a gun for firing projectiles in succession across a space to a platen having a printing area to form characters on a medium placed against the platen, including the steps of positioning the gun spaced above a horizontal plane normal to and above the boundary of said printing area and moving the gun to form characters in successive steps, each moving step in a vertical direction being from bottom to top, whereby every subsequently fired projectile prints in a direction away from a previously fired projectile rebounding from the platen.
Claim 5
Independent Claim
98 words
A method of operating a microballistic printer having a gun for firing projectiles in succession across a space to a platen having a printing area to form characters on a medium placed against the platen, including the steps of positioning the gun spaced below a horizontal plane normal to and below the boundary of said printing area and moving the gun to form characters in successive steps, each moving step in a vertical direction being from top to bottom, whereby every subsequently fired projectile prints in a direction away from a previously fired projectile rebounding from the platen.
Claim 6
Independent Claim
98 words
A method of operating a microballistic printer having a gun for firing projectiles in succession across a space to a platen having a printing area to form characters on a medium placed against the platen, including the steps of positioning the gun spaced below a horizontal plane normal to and below the boundary of said printing area and moving the gun to form characters in successive steps, each moving step in a vertical direction being from top to bottom, whereby every subsequently fired projectile prints in a direction away from a previously fired projectile rebounding from the platen.
Claim 7
Independent Claim
101 words
A method of operating a microballistic printer having a gun for firing projectiles in succession across a space to a platen having a printing area to form characters on a medium placed against the platen, including the steps of positioning the gun spaced to the left of a vertical plane normal to and to the left of said printing area and moving the gun to form characters in successive steps, each moving step in a horizontal direction being from right to left, whereby every subsequently fired projectile prints in a direction away from a previously fired projectile rebounding from the platen.
Claim 8
Independent Claim
101 words
A method of operating a microballistic printer having a gun for firing projectiles in succession across a space to a platen having a printing area to form characters on a medium placed against the platen, including the steps of positioning the gun spaced to the left of a vertical plane normal to and to the left of said printing area and moving the gun to form characters in successive steps, each moving step in a horizontal direction being from right to left, whereby every subsequently fired projectile prints in a direction away from a previously fired projectile rebounding from the platen.
Claim 9
