cannot telnet port 515

[R.O.]

Hi,

I Have a problem with a label printer Markpoint MP104 Compact. Since few days ago, all the print jobs remains queued and I cannot print anything. I try to connect this printer by port 515 but:

Trying...
telnet: Unable to connect to remote host: Connection refused

I can telnet other printers in same subnet. Also, I can ping this printer...
Does anybody knows where the problem is?

Regards,

[Steve Steel]

wait 10

With the 'cancel' command you should be able to remove the hung print job. Follow this procedure if you can't:

cd /var/spool/lp
lpshut
rm FIFO, SCHEDLOCK, outputq, *lock
>outputq
>log
ps -ef | grep -i lp
kill -9 any processes
lpsched -v
more log
lp -d printer file

Hello,

I already try these two things. I can cancel -e the jobs:

# cancel -e printer1
request "printer1-7" cancelled
connection to xxx.xx.x.xxx is down

But I can ping this ip...

I also try power off-power on.

Can you telnet into the printer? If not, but you can ping, then layer 1 through 3 are up but layer 4 is not. Layer 4 is the transport layer which can be blocked by a firewall. Other connectivity checks, use 'arp -a' and cross reference your ip to your MAC then 'linkloop MAC'. This verifies layer 2.
