First Claim
Patent Images
1. A printer connected to a print quality verifier comprising:
- a printer having printing elements for printing on a media;
means for supplying media to be printed upon by said printer;
a verifier connected to said printer for verifying the quality of print on said media;
a controller in said printer for receiving data from said verifier to provide a signal for corrective quality control of said printer; and
, wherein said verifier verifies the quality of a bar code as printed as to two or more criteria selected from the group consisting of encodation failure, quiet zone failure, symbol contrasts, percent decode, defects failure, decodability failure, or a missing report pertaining to said printer output.

Abstract
This disclosure sets forth a verifier for verifying the quality of print such as bar codes in combination with a printer wherein the printer can be controlled to provide proper printing functions for printing in response to the verifier input. The printer upon receipt of a particular report from the verifier can stop the printing such as bar code printing as to a bad label, overstrike a bad label, or reprint the label. Further to this extent, the printer can be controlled by operator intervention on the control panel or by automatic input through the controller of the printer to provide for the respective necessary and correct print or bar codes being printed.
