Printer Self Test; Integral Printer Test Pattern - HP 262SA Reference Manual

Integral Printer Control
The keyboard is disabled CClocked") until the status is sent.
In either Character or Block Line mode, the terminal sends a <CR> (or a <CR > <LF> ifAuto
Linefeed mode is enabled) following the completion code. In Block Page mode, it sends a block
terminator character.
If a datacomm error occurs during transmission of the data record, the device control comple-
tion code is unpredictable. Datacomm errors are reported by way of the terminal status bytes
described in Section 8.
PRINTER SELF TEST
The terminal has a printer self test feature that exercises the printer's capabilities to verify
that it is functioning properly.
The printer self test cannot be initiated from a program. To initiate the test from the key-
board, press the following keys, in sequence:
_, service keys, INT PRT TEST
If the printer is functioning properly, it will generate the test pattern illustrated in figure
C-5.
