Method for aligning two or more independent printing systems with a single control unit and intelligent print controllers
View Patent ↗A method and system receives a print job from a host device, parses the print job into individual print data for at least two separate printing devices, generates a random set of marks for identification of the print job, embeds the identification marks into the individual print data for a first printing device; and sends the individual print data and the marks to each printing device. Simultaneously, each printing device in the system receives its individual dataset for printing and the set of identification marks from the control unit and starts its print engine at a high speed. The first printing device prints its dataset and the identification marks on at least a first page of the printed dataset. The remaining printing devices then scan the roll of print media until they recognize the matching identification marks and begin printing their individual dataset on the roll of print media.
1. A method comprising the steps of:
receiving a single print job from a host;
parsing the single print job into a first and a second individual print data for a first and a second separate printing devices, respectively;
generating a random set of marks for identification of the single print job;
embedding the random set of identification marks into the first individual print data for subsequent printing on a print media with the first individual print data by the first printing device;
sending the first individual print data to the first printing device;
sending the random set of marks for identification to the second printing device;
moving the print media through each of the first and second separate printing devices in unison; and
printing the single print job by printing the first individual print data including the random set of marks for identification onto the print media by the first printing device and printing the second individual print data onto the print media by the second printing device.
2. A method comprising the steps of:
receiving a print job from a host;
parsing the print job into individual print data for at least two separate printing devices;
generating a random set of marks for identification of the print job;
embedding the random set of identification marks into the individual print data for a first printing device;
sending the individual print data and the random set of marks to each printing device;
starting to move print media through each of the at least two separate printing devices from a stopped state; and
printing the individual print data for the first printing device including the random set of marks for identification onto the print media by the first printing device.
3. The method of claim 2 , wherein the step of starting to move print media comprises starting each of the at least two separate printing devices independently.
4. The method of claim 2 , wherein the step of starting to move print media comprises starting each of the at least two separate printing devices in unison.
5. A computer readable medium including computer instructions for driving a control unit, the computer instructions comprising instructions for:
receiving a single print job from a host;
parsing the single print job into a first and a second individual print data for a first and a second separate printing devices, respectively;
generating a random set of marks for identification of the single print job;
embedding the random set of identification marks into the first individual print data for subsequent printing on a print media with the first individual print data by the first printing device;
sending the first individual print data to the first printing device;
sending the random set of marks for identification to the second printing device;
starting to move the print media through each of the first and second separate printing devices in unison; and
printing the single print job by printing the first individual print data including the random set of marks for identification onto the print media by the first printing device and printing the second individual print data onto the print media by the second printing device.
6. A computer readable medium including computer instructions for driving a control unit, the computer instructions comprising instructions for:
receiving a print job from a host;
parsing the print job into individual print data for at least two separate printing devices;
generating a random set of marks for identification of the print job;
embedding the random set of identification marks into the individual print data for a first printing device;
sending the individual print data and the random set of marks to each printing device;
starting to move print media through each of the at least two separate printing devices from a stopped state; and
printing the individual print data for the first printing device including the random set of marks for identification onto the print media by the first printing device.
7. The computer readable medium of claim 6 , wherein the step of starting to move print media comprises starting each of the at least two separate printing devices independently.
8. The computer readable medium of claim 6 , wherein the step of starting to move print media comprises starting each of the at least two separate printing devices in unison.
