Abstract
A printer 3 with a paper consumption output function resets the count of a paper consumption counter 32 (ST22) when a start measuring command C1 is received from the host computer 2 side, and measures the paper consumption 32A from a specific start measurement time to a specific stop measurement time using a paper consumption counter 32 (ST23b to ST27b). When a fetch paper consumption command C2 is received (ST41), the printer 3 outputs the paper consumption 32A, which is the count of the paper consumption counter 32, to the host computer 2 (ST43).
Claims19
A paper consumption method of a printer comprising a print head, the method comprising:
- executing a start measuring command that commands starting measuring paper consumption;
- executing a fetch paper consumption command that commands outputting the paper consumption;
- resetting a count of a paper consumption counter when the start measuring command is received;
- measuring the paper consumption from a specific start measurement point to a specific stop measurement point using the paper consumption counter;
- and
- outputting the paper consumption expressed by the count of the paper consumption counter to an external device when the fetch paper consumption command is received.
A printing system comprising:
- a host computer;
- and
- a printer that drives a printer printhead and a printer paper conveyance mechanism, and prints on paper, based on a command and print data supplied from the host computer;
- the host computer having a command generator that generates a start measuring command that commands measuring paper consumption by the printer, and a fetch paper consumption command that commands outputting the measured paper consumption;
- and
- the printer having a paper consumption counter formed in volatile memory,
- a start measuring command execution unit that executes the start measuring command, and
- a fetch paper consumption command execution unit that executes the fetch paper consumption command.
A printer comprising:
- a paper consumption counter formed in volatile memory;
- a start measuring command execution unit that executes a start measuring command that commands starting measuring paper consumption;
- and
- a fetch paper consumption command execution unit that executes a fetch paper consumption command that commands outputting the paper consumption;
- the start measuring command execution unit resetting a count of the paper consumption counter when the start measuring command is received, and measuring the paper consumption from a specific start measurement point to a specific stop measurement point using the paper consumption counter, and
- the fetch paper consumption command execution unit outputting the paper consumption expressed by the count of the paper consumption counter to an external device when the fetch paper consumption command is received.
