AXIS 540/640 User’s Manual 81
Read-back of
information
The AXIS 540/640 supports bi-directional printing. The information
from the printer is read back on the parallel port when the parameter
PRx_IN has the default setting of AUTO. However, it is required that
the printer also supports bi-directional printing. Through the
parameter PRx_IN the communication can be disabled.
Example:
The following entry is needed in your config file to disable the bi-
directional communication:
Debugging using the
Hex Dump Mode
When hex dump mode is activated, the print data is printed as
hexadecimal byte values rather than characters; printer control
commands are also printed as hex values. This allows you to inspect
what control and print characters are being sent to the printer, which
is a useful debugging facility for the more difficult printing problems.
Example:
The following is an example of the entries needed in your config
file to activate the hex dump mode for PR3:
Note: ❏ The page length for hex dump printouts is determined by the
lines per page value of the PostScript page format parameter.
PR1_IN. : NONE (Read-back of information)
PR3_DUMP.:YES (switch on hex dump mode for PR 3)
