Is provided in the storage means.

In addition to printing out based on the received print data, the printing operation is controlled by the setting information consisting of a plurality of setting items input by the operation unit, and the plurality of setting information is registered in the storage means. In the printing device that holds
It is characterized by further comprising control means for registering / holding only the changed setting item in the storage means based on the information for discriminating the changed setting item among all the setting items.

Further, the control means performs control to register / hold only the changed setting item in the storage means on the basis of the information for discriminating the changed setting item among the designated setting items. And

Further, when the same setting information exists in the registered setting information, the control means registers the setting information in the storage means by using the registration number of the previously registered setting information. It is characterized in that control for holding is performed.

[0009]

According to the printing apparatus having the above configuration, only the designated setting item is registered / held in the storage unit by the control unit based on the information for discriminating the designated setting item among all the setting items. It is not necessary to register all items of the setting information of the printing environment.

Further, based on the information for discriminating the changed setting item among all the setting items, only the changed setting item is registered / held in the storage means by the control means, so that all the items of the setting information of the printing environment are stored. No need to register.

Further, the control means performs control to register / hold only the changed setting item in the storage means based on the information for discriminating the changed setting item among the designated setting items. It is not necessary to register all items of setting information.

Further, when the same setting information exists in the registered setting information, the control means registers and holds the setting information in the storage means by using the registration number of the previously registered setting information. Since the control is performed, it is not necessary to register all the items of the print environment setting information.

When registering and holding the setting information of the printing environment, the registration item table is referred to and only the value of the item is registered in the NVRAM 4.

FIG. 3 is a flow chart relating to the registration of the first registration example. The item number is checked in the registration item table (S1), and if it is the item number to be registered (YES in S2), the value of the item is set. Register (S3) and until registration is complete (S4: N
O), and shifts to the next setting item (S5).

When calling a registered item, initial values are set for items other than those specified in the registered item table.

FIG. 4 is an explanatory view showing a second example of registration of setting items. A header section showing the registration attribute of each item is prepared, and the header section showing the attribute is also registered together with the value of the item to be registered. To do so. Each bit of the header indicating the registration attribute corresponds to all setting items, and the attribute of the registered item is "1".
The attribute of the item that is not registered is set to "0".
Register the registered item values in ascending order of item number.

FIG. 5 is a flowchart relating to the registration of the second registration example. The registration attribute header is used to check the registration attribute of the item (S11), and if the registration attribute is ON (YE in S12).
S), register the value of the item (S13), and complete the registration.
(NO in S14), the process proceeds to the next setting item (S15).

FIG. 6 is an explanatory diagram showing a third example of registration of setting items, in which only changed items are registered among all items of the setting information of the printing environment. Since the printer normally holds the initial value of each setting item, at the time of registration, each item is compared with the initial value to determine whether the item has been changed, and only the changed item is registered. Items that have not been changed are not registered. And the second
Register using the registration example method.

FIG. 7 is a flowchart relating to the registration of the third registration example, in which the current value of the setting item is compared with the initial value (S2
1) If it has been changed (YES in S22), the corresponding bit of the registration attribute header is set to "1" (S23), and if it has not been changed (NO in S22), the registration attribute header The corresponding bit of is set to "0" (S24). When set to "1", the value of the item is registered (S25), and until the registration is completed (NO in S26), the process proceeds to the next setting item (S2).
