Configuring Printers with WebLink
Configuring Weblink
10/31/13 P1058563-003
The logging settings are atypical to the Weblink settings as they do not require the printer to be
reset before taking effect. This does not mean that previous logging messages that would have
been logged will appear when the
max_entriessetting is changed from zero (0) to a greater
value. It means that any new logging messages will be logged from that point forward.
Issue the following command to clear any log entries currently in the
weblink.logging.entries buffer.
!U1do"weblink.logging.clear"""
Navigating the Log Output
The log will contain useful information, even in the scenario where the printer successfully
connects to the remote server. This section explains how to read the log and highlights some of
the key entries that will help to determine if the connection was successful.
A typical log entry looks as follows:
[12‐04‐201214:57:10.625][conn1.1]Attemptingconnectionto

The first column is the date and time that the event occurred. The format of the date and time
matches the format of
rtc.date and rtc.time. The time, however, also includes the
milliseconds to aid in troubleshooting network latency concerns.
The second column indicates the connection name and channel that the entries are associated
with. The connection name will match the weblink branch that was configured with the
respective URL (for example, conn1 or conn2). The channel number indicates which channel
on the respective connection that the entries corresponds to.
The third column is the actual message, which contains information about what occurred in the
printer at the corresponding time in column one. In the above example, the printer was
initiating the connection to the URL specified in
weblink.ip.conn1.location.
Review the section titled SSL/TLS Certificate Errors on page 60 to understand what it means
when certain logging messages/errors appear in the log.
Note • For printers that do not have a battery to store the Real Time Clock (RTC) value, the
date will be restored to the default value upon a power cycle. The default value depends upon
how the rtc.date Set/Get/Do (SGD) is managed. If it has never been set, then it will default to
the firmware build date (the value in appl.date). Otherwise, the value in rtc.date will default
to the value that it was last set to. This does not mean the value of the rtc.date when it was
power cycled – it means that when a user sets
rtc.date, that value becomes the new default
value. If the printer has a battery, then the
rtc.date never defaults and continues to track the
date as expected.
Note • Channels are additional connections that are requested by the server when the server
needs to perform a specific operation that cannot be done on the channel(s) currently open.
Typically only the RAW channel is open, which operates similar to the RAW TCP port. It is
typical to see two channels opened—the main channel and the RAW channel.
