Abstract

PURPOSE:To automatically output dot pattern data fitted to the kinds of host apparatuses and to prevent a printing mistake, by mounting a dot pattern data memory part accessible from a plurality of address parts corresponding to character code signals and selecting one address part by the kinds of the host apparatuses. CONSTITUTION:A machine kind judge part 1 specifies a host apparatus on the basis of the control signal or character code signal from the host apparatus and selects one of address parts 3, 4 to select a fitted address part 3. By this operation, the character code signal outputted from the host apparatus applies access to a dot pattern data memory part 2 through the address part 3 to be converted to predetermined dot pattern data which is, in turn, stored in a line buffer memory before printed by a printing head. When the machine kind judge part 1 is connected to a different kind of a host apparatus, said judge part 1 selects the address part 4. By this method, the character code signal outputted from a separate kind of the host apparatus is converted to predetermined dot pattern data regardless of the alteration of the host apparatus.

れ前述のアドレス部であっ、て、機種判定部１がらの。FIG. 1 shows an embodiment of the present invention, and reference numeral 1 in the figure is a model determination section that selects an address section 3.4 to be accessed corresponding to the connected host device. It is configured as follows. Reference numeral 2 denotes a dot pattern data storage section, which is configured such that dot pattern data corresponding to an input character code signal can be accessed from any of address sections 3 and 4, which will be described later. 3 and 4 are the aforementioned address sections, respectively, and are from the model determination section 1.

ッドにより印字される。In this embodiment, when the main body of the printer device is connected to the host device, the model determination section 1 identifies the host device based on the control signal and character code signal from the host device, and selects one of the address section 3 and address section 4. A suitable address section, for example address section 3, is selected. As a result, the character code signal output from the host device is accessed via the address section 3 to the dot pattern data storage section 2, converted into predetermined dot pattern data, and stored in a line buffer memory (not shown) before being printed. Printed by the head.

れる。Further, when this printer device is connected to a host device of a different model, the model determining section 1 identifies the host device and selects the address section 4 based on the control signal and character code signal from the host device. As a result, a character code signal outputted from a host device of a different model is converted into predetermined dot pattern data by accessing the data storage section 2 with a dot pattern via the address section 4, regardless of the model change.

Since the address part can be selected, just by connecting the host device, dot pattern data matching the model can be automatically output, which can help prevent printing errors and the like. Instead, the dot pattern data can be used in common, and memory capacity can be saved.
