Claims

[Scope of utility model registration request]

The pattern information that drives all the printing elements of the print head is stored in the address area that is not used for character pattern storage in the character generator that stores the specified character pattern, and when printing the test pattern. A line tod characterized by being configured such that by specifying and reading out pattern information for all dot printing, all printing elements are driven in one dot line and a linear continuous pattern can be printed. Printer test pattern generator.
