Abstract

Methods and systems print markings on a web of media using a printer to produce a printed roll of media. During the printing, the printer automatically analyzes the internal printer conditions, and automatically identifies printing errors based on the internal printer conditions during the printing. Further, such methods and systems automatically record the printing errors in an error log file using a computerized device that is operatively connected to the printer and store the error log file in a network storage element within a computerized network. Also, such methods and systems transmit the error log file from the computerized device (or the network storage element) to a post-printing processing device using the computerized network after receiving a request for the error log file. The post-printing processing device unwinds the printed roll and automatically stops the unwinding process at locations of the printing errors based on the error log file.

Claims

1. A system comprising:

a printer printing markings on a web of media to produce a printed roll of media, said printer automatically identifying printing errors during said printing;

a computerized device operatively connected to said printer, said computerized device automatically recording said printing errors in an error log file;

a computerized network operatively connected to said computerized device; and

a post-printing processing device operatively connected to said computerized network,

said computerized device transmitting said error log file to said post-printing processing device through said computerized network,

said post-printing processing device unwinding said printed roll, and

said post-printing processing device automatically stopping said unwinding at locations of said printing errors based on said error log file.

2. The system according to claim 1, said post-printing processing device making a request for said error log file.

3. The system according to claim 1, further comprising a network storage element within said computerized network, said computerized device storing said error log file in said network storage element.

4. The system according to claim 3, said error log file being transmitted from said network storage element to said post-printing processing device.

5. The system according to claim 1, said post-printing processing device one of automatically and manually reading printed data from said printed roll of media, said printed data identifying said error log file.

6. The system according to claim 1, said identifying printing errors being identified only by said printer and being based only on sensors internal to said printer.

7. A system comprising:

a printer printing markings on a web of media to produce a printed roll of media, said printer automatically analyzing internal printer conditions during said printing, and said printer automatically identifying printing errors based on said internal printer conditions during said printing;

a computerized device operatively connected to said printer, said computerized device automatically recording said printing errors in an error log file;

a computerized network operatively connected to said computerized device; and

a post-printing processing device operatively connected to said computerized network,

said computerized device transmitting said error log file to said post-printing processing device through said computerized network,

said post-printing processing device unwinding said printed roll, and

said post-printing processing device automatically stopping said unwinding at locations of said printing errors based on said error log file.

8. The system according to claim 7, said post-printing processing device making a request for said error log file.

9. The system according to claim 7, further comprising a network storage element within said computerized network, said computerized device storing said error log file in said network storage element.

10. The system according to claim 9, said error log file being transmitted from said network storage element to said post-printing processing device.

11. The system according to claim 7, said post-printing processing device one of automatically and manually reading printed data from said printed roll of media, said printed data identifying said error log file.

12. The system according to claim 7, said identifying printing errors being identified only by said printer and being based only on sensors internal to said printer.

13. A method comprising:

printing markings on a web of media using a printer to produce a printed roll of media;

automatically identifying printing errors during said printing using said printer;

automatically recording said printing errors in an error log file using a computerized device operatively connected to said printer;

transmitting said error log file from said computerized device to a post-printing processing device using a computerized network operatively connected to said computerized device and said post-printing processing device;

unwinding said printed roll using said post-printing processing device; and

automatically stopping said unwinding at locations of said printing errors based on said error log file using said post-printing processing device.

14. The method according to claim 13, further comprising making, by said post-printing processing device, a request for said error log file.

15. The method according to claim 13, further comprising storing, by said computerized device, said error log file in a network storage element within said computerized network.

16. The method according to claim 15, said transmitting said error log file comprising transmitting said error log file from said network storage element to said post-printing processing device.

17. The method according to claim 13, further comprising one of automatically and manually reading printed data from said printed roll of media using said post-printing processing device, said printed data identifying said error log file.

18. The method according to claim 13, said identifying printing errors being identified only by said printer and being based only on sensors internal to said printer.

19. A method comprising:

printing markings on a web of media using a printer to produce a printed roll of media;

automatically analyzing internal printer conditions during said printing using said printer;

automatically identifying printing errors based on said internal printer conditions during said printing using said printer;

automatically recording said printing errors in an error log file using a computerized device operatively connected to said printer;

transmitting said error log file from said computerized device to a post-printing processing device using a computerized network operatively connected to said computerized device and said post-printing processing device;

unwinding said printed roll using said post-printing processing device; and

automatically stopping said unwinding at locations of said printing errors based on said error log file using said post-printing processing device.

20. The method according to claim 19, further comprising making, by said post-printing processing device, a request for said error log file.

21. The method according to claim 19, further comprising storing, by said computerized device, said error log file in a network storage element within said computerized network.

22. The method according to claim 21, said transmitting said error log file comprising transmitting said error log file from said network storage element to said post-printing processing device.

23. The method according to claim 19, further comprising one of automatically and manually reading printed data from said printed roll of media using said post-printing processing device, said printed data identifying said error log file.

24. The method according to claim 19, said identifying printing errors being identified only by said printer and being based only on sensors internal to said printer.
