Abstract
Abstract A high speed line printer is provided which may be incorporated as a component of an off-line system for printing encoded identification data on labels, or the like. The particular system to be described accepts the output of a data processor, as recorded on a magnetic tape, and it automatically transforms the recorded information into human-readable characters and code bar machine-readable symbols, which are imprinted on labels or other forms. The printer to be described is a drum type, impact, line printer, which is capable of high speed operation, and which is controllable to print out alphanumeric and special characters, as well as a set of code bar symbols for a variety of tag and label sizes, with a high degree of speed, precision and accuracy.

Claim 1
Independent Claim
326 words
In a high speed line printer system which includes a frame; a print drum rotatably mounted on said frame and having a plurality of different bar code symbols engraved on the peripheral surface thereof in a plurality of different longitudinal rows angularly spaced around the periphery from one another, and with each row containing identical bar code symbols; a paper drive mechanism mounted on said frame for moving forms on a line-to-line basis past said print drum to be imprinted by said bar code symbols; impact hammer means mounted on said frame; control circuitry coupled to said impact hammer means for causing said impact hammer means to drive said forms agaInst the bar code symbols on said print drum at controlled times; electrical signal generating means coupled to said paper advance mechanism for producing electric pulses representative of each line advance of said paper drive mechanism with respect to a first predetermined line per inch reference standard; a format control system mechanically coupled to said paper drive mechanism and to said generating means for generating electrical control signals indicative of advances of said forms by said paper drive mechanism through predetermined numbers of lines; the combination of an encoder mechanically coupled to said paper advance mechanism for generating an electric signal representative of each line of advance of said paper drive mechanism with respect to a second predetermined line per inch reference standard; logic circuitry electrically connected to said format control system and to said encoder for generating electric output signals selectively representative of the electrical control signals from said format control system and of said electric signal from said encoder; and control means coupled to said paper drive system and responsive to the output signals from said logic circuitry to stop the paper drive system at predetermined positions of the forms under the control of the format control system during one operating mode and under the control of the encoder during a second operating mode.

Claim 5
Dependent Claim
72 words
The high speed line printer system defined in claim 1, in which said control means responds to signals from said logic circuitry during the first operating mode to move the paper drive mechanism from one form to the next, and in which said control means responds to the output signals from said logic circuitry during the second operating mode to move the paper drive mechanism to selected lines within the individual forms.
