Abstract

A label printer that can either transfer information from graphic masters (such as cards) to copy stock (such as labels) or -print" copies directly from information stored conven-tionally on magnetic computer tape. There are three steps in the process: (1) Translate the input to a latent electro-static image on an insulator. (2) Develop the image by causing ink to coat the charged areas, (3) Print the copy by contact transfer of the ink to the copy stock,

A label printer that can either transfer information from
graphic masters (such as cards) to copy stock (such as labels)
or ~print" copies directly from information stored conven-~
tionally on magnetic computer tape. There are three steps in
the process: (1) Translate the input to a latent electro~
static image on an insulator. (2) Develop the image by
causing ink to coat the charged areas, (3) Print the copy by
contact transfer of the ink to the copy stock,

The printer includes an electronic scanner 10 for reading a
graphic master 11, a print matrix 12 for selectively charging
a moving insulated belt 14 in response to signals from scanner
10, a magnetic ink applicator 15 for developing the image
charge pattern on belt 14 with ink, a transfer station 16 for
transferring the ink image from belt 10 to copy stock 17, and a
cleaning/charge neutralizing station 18 for removing leftover
ink and/or charges,

A TECHNIQUE FOR PRODUCING GRAPHICS ON PLAIN PAPER FROM COMPUTER
INPUTS (Cont'd)

As an alternate input, information may be stored on magnetic
tape 20 for input through decoder 21 to print matrix 12. Input
choice is by means of selector 22,

An input/output buffer is established by providing s...
