Abstract

Provided is a printing device including a print data receiving unit, a page calculation unit that calculates a number of pages before stopping with using a page length of received print data and a distance from a printing mechanism unit to a visual recognition unit, a print instruction unit that changes the number of pages before stopping or a number of printed pages and performs print processing when the received print data corresponds to a control page for controlling printing, and a print stop unit that stops printing when the number of printed pages coincides with the number of pages before stopping.

First claim

What is claimed is:

1. A printing device comprising:
at least one processor configured to:
receive print data;
before executing a stop printing operation:
calculate a total number of pages using a page length of the received print data and a distance from a printer to a visual recognition part; and
change the total number of pages to be printed or a number of printed pages and perform print processing in response to the received print data corresponding to a control page for controlling printing; and
executing the stop printing operation in response to the number of printed pages coinciding with the total number of pages to be printed,
wherein the at least one processor is further configured to, before the executing the stop printing operation, change the distance from the printer to the visual recognition part from an actual value to a logical value and calculate the number of pages to be printed.

2. The printing device according to claim 1 ,
wherein the at least one processor is further configured, before the executing the stop printing operation, to increase the count of the number of pages to be printed in response to executing printing of the control page.

3. The printing device according to claim 2 ,
wherein a code indicating the control page is configured to be added to the control page in the print data.

4. The printing device according to claim 2 , further comprising:
a storage configured to store distances from a plurality of printers corresponding to a plurality of device configurations to the visual recognition part in a table,
wherein the at least one processor is further configured to, before the executing the stop printing operation, read the distance from the printing mechanism corresponding to an own device configuration to the visual recognition part from the table in the storage and calculate the number of pages to be printed before executing the stop printing operation.

5. The printing device according to claim 1 ,
wherein the at least one processor is configured to, before the executing the stop printing operation, maintain the count of the number of pages to be printed in response to executing printing of the control page.

6. The printing device according to claim 5 ,
wherein a code indicating the control page is configured to be added to the control page in the print data.

7. The printing device according to claim 5 , further comprising:
a storage configured to store distances from a plurality of printers corresponding to a plurality of device configurations to the visual recognition part in a table,
wherein the at least one processor is further configured to, before the executing the stop printing operation, read the distance from the printer corresponding to an own device configuration to the visual recognition part from the table in the storage and calculate the number of pages to be printed before executing the stop printing operation.

8. The printing device according to claim 1 ,
wherein a code indicating the control page is configured to be added to the control page in the print data.

9. The printing device according to claim 1 , further comprising:
a storage configured to store distances from a plurality of printers corresponding to a plurality of device configurations to the visual recognition part in a table,
wherein the at least one processor is further configured to, before the executing the stop printing operation, read the distance from the printing mechanism corresponding to an own device configuration to the visual recognition part from the table in the storage and calculate the number of pages to be printed before executing the stop printing operation.

10. The printing device according to claim 1 , wherein the at least one processor is further configured to:
detect replenishment of paper and, in response to detecting
the replenishment of the paper, the calculate the number of pages to be printed before stopping the printing to replenish paper.

11. A printing device comprising:
at least one processor configure to
sequentially print a plurality of pages on continuous paper, on which a form is printed in advance, using print data including a control page for controlling printing and a user page required by a user;
a visual recognition part configured to visually recognize a print state on paper on which the print data is printed;
wherein the at least one processor is further configured to:
calculate a number of pages to be printed before stopping printing using a page length obtained from the print data and a visual recognition distance from the printer to the visual recognition part;
accumulate a number of pages on which the printer is configured to print and determines the number of pages to be a number of printed pages;
before executing a stop printing operation
change the number of pages to be printed or the number of printed pages and perform print processing in response to a page to be printed by the printer being the control page;
stop the printing by the printer for visual recognition of a user page to be checked through the visual recognition part in response to the number of pages to be printed coinciding with the number of printed pages; and
change the distance from the printer to the visual recognition part from an actual value to a logical value and calculate the number of pages to be printed before executing the stop printing operation.

12. A printing system comprising:
a first printing device coupled to a second printing device,
wherein the first printing device comprises at least one first processor and the second printing device comprises at least one second processor, the at least one first processor and the at least one second processor are configured to:
receive data;
before executing a stop printing operation:
calculate a total number of pages to be printed using a page length of the received print data and a distance from a printer to a visual recognition part;
change the number of pages to be printed and perform print processing in response to the received print data corresponding to a control page for controlling printing; and
executing the stop printing operation in response to the number of printed pages coinciding with the number of pages to be printed before executing the stop printing operation,

wherein the at least one first processor in the first printing device is further configured to, before the executing the stop printing operation, set the number of pages to be printed in the second printing device in response to the received print data including a control page for controlling printing by the second printing device, and
wherein in response to one of the first printing device and the second printing device executing the stop printing operation, the other one of the first printing device and the second printing device also executes the stop printing operation, and
wherein the at least one first processor and the at least one second processor are further configured to change the distance from the printer to the visual recognition part from an actual value to a logical value and calculate the number of pages to be printed before executing the stop printing operation.
