problems
You can check some of the same problem notes in the
terminal section because most are applicable to printers.
The main problem is with cabling.
If you experience printer problems, it's a good idea to
temporarily connect a terminal in place of the printer so you
can ensure some of the basic functions are working
correctly. Simply telnet into the terminal server port:
telnet elroy 10006 (port 6 on Terminal Server elroy)
If the Telnet session will not connect, check the network and
if you are using any of the RS-232 flow control signals,
ensure they are connected correctly. If the telnet session still
refuses to operate, re-configure the port for normal terminal
operation and trouble-shoot again from this level.
Another method is the use the test command from the CLI.
This sends a continuous test pattern out to the printer.
Example for port 6 (press
local> test port 6 count 0
If there is no printout, check the cable or the printer.
If characters disappear from the printout it may be due to a
flow control problem, therefore check that the flow control is
set to be the same at both ends of the cable and re-try.
Alternatively, the host software may be incorrectly
configured. If you are using ioland , set the debug level to a
high value so that the log file will contain as much
information as possible.
