Abstract

A printer for printing bar code on labels as shown in Fig. 1, comprises as shown in Fig. 2, a rotating drum 10 having a plurality of bar code segments 12 about the periphery and a plurality of print hammers 14. The print hammers may be repeatedly operated to produce the necessary length of bar code on a document 16, which is advanced past the drum and hammers by a feed roll 18 in conjunction with a ribbon 20.

Label Printer

A printer for printing bar code on labels as shown in Fig. 1, comprises as shown in Fig. 2, a rotating drum 10 having a plurality of bar code segments 12 about the periphery and a plurality of print hammers 14. The print hammers may be repeatedly operated to produce the necessary length of bar code on a document 16, which is advanced past the drum and hammers by a feed roll 18 in conjunction with a ribbon 20.

As shown in Fig. 3, a staggered array of graphics may also be provided on another portion of the drum to provide human readable graphics.

The odd print position and even print position graphics are alternately staggered in axial rows to minimize shadow printing. The graphics are arranged in annular columns to produce minimum shadow within the column. As shown in the table of Fig. 4, each bit is a bar approximately 0.014" wide. 0 is white and 1 is black.

The hammer arrangement is shown schematically in Fig. 5.

Printing occurs as follows:

(1) The strip 16 is registered so that the top of the printing

area is in front of the hammers 14.

(2) The first line is completely printed.

(3) Synchronized motion of the label commences either in

increments or by a slow creep, and bar codes are formed

by successive hammer strokes.

(4) The class code may be printed half-way through step 3.

(5) The document 16 is stopped and the last row of bar code

characters are printed. Steps 1, 2 & 5 provide even tops

and bottoms to the bar.

(6) The remaining line of print c...
