The AXIS 540+/AXIS 560 supports bi-directional printing. The information from
the printer is read back on the parallel port when the parameter Read Back Port
(PRx_IN.) has the default setting of AUTO. However, it is required that the
printer also supports bi-directional printing.
Please refer to your printer documentation for further details regarding bi-
directional printing support.
Follow the instructions below to disable the bi-directional communication for
logical printer PR1:
1. From the print server's internal Web page, select Admin | Logical
Printers.
2. Select the PR1 tab.
3. Set the Read Back Port parameter to NONE.
4. Click the OK button.
When hex dump mode is enabled, 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 actually
being sent to the printer, which is a useful debugging facility for more difficult
printing problems.
Follow the instructions below to enable the hex dump mode for PR3:
1. From the print server's internal Web page, select Admin | Logical
Printers.
2. Select the PR3 tab.
3. Set the Hex Dump Mode Enabled radio button to YES.
4. Click OK.
The page length for hex dump printouts is determined by the lines per page value of the
PostScript page format parameter.
