Axis Communications 540/640 manual Read-back of information

Section 7: Setting Up - UNIX

Read-back of The AXIS 540/640 supports bi-directional printing. The information 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:

PR1_IN. : NONE (Read-back of information)

Debugging using the When hex dump mode is activated, the print data is printed as Hex Dump Mode 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:

PR3_DUMP.:YES (switch on hex dump mode for PR 3)

Note: ❏ The page length for hex dump printouts is determined by the lines per page value of the PostScript page format parameter.
