Printronix P9000 Series manual Examples, Example 1 Characters with No Attributes

Examples

The following examples illustrate the process of creating three characters: one with no attribF utes, one with descenders, and one with extenders.

NOTE: If adjacent dots are used to create the character, the printer will set an adjacent dot flag, and any line containing the character may print at half the normal speed. Half speed may also result if a dot is placed in the first or last dot column of the character cell.

Example 1: Characters with No Attributes

NOTE: This example illustrates how OCR characters could be produced using the downloading feature should an OCR reader fail to read standard OCR printed charac/ ters.

Adjacent dots in rows 1 and 8 may result in half-speed printing of those dot rows.
