 Posted: Fri Feb 22, 2008 12:22 pm Post subject: [Abandoned] HP JetDirect en3700 refusing TCP connections |
 |
|
Hello,
I have an HP Color Laserjet 3550 which I am attempting to set up for access over a small local network. The printer IP is assigned by DHCP with no problems and it can be pinged. nmap shows the expected services running:
| Code: |
nmap xx.xx.xx.yy
PORT STATE SERVICE
21/tcp open ftp
23/tcp open telnet
80/tcp open http
280/tcp open http-mgmt
443/tcp open https
515/tcp open printer
631/tcp open ipp
9100/tcp filtered jetdirect
|
9100 is filtered, which is likely the problem. Unfortunately I have not yet been able to get it to allow any hosts.
It is possible to telnet to the printer on port 23, and from there enter the TCP configuration.
The configuration is currently:
| Code: |
TCP/IP - ACCESS CONTROL
-----------------------------------------
---------------------------------------------------
| Allow | IP Address | Mask |
---------------------------------------------------
| Allow[1] | 192.168.1.0 | 255.255.255.0 |
---------------------------------------------------
|
Unfortunately, nothing can be printed (via cups) and the TCP access log shows rejected TCP connections after each attempt.
Any ideas?

Hi,
I've used the CUPS admin on localhost:631. I have just removed and re-installed the printer to use the following URI:
ipp://192.168.1.228:631
I then try to send a testpage from cups webadmin, the job sits as 'processing' but never prints.
nmap of printer IP address is :
| Code: |
21/tcp open ftp
23/tcp open telnet
80/tcp filtered http
280/tcp open http-mgmt
443/tcp open https
515/tcp open printer
631/tcp open ipp
9100/tcp open jetdirect
|
Anyone got one of these working over tcp? Failing this I guess I'll just go for USB connection, downside is then another host has to up the whole time - not eco friendly!
Cheers
Chris

Quick follow up. Bizarrely, after adding another printer on
ipp://192.168.1.228/631
and trying to print a test page, nmap now shows 631/ipp as being filtered. This printer doesn't want me in there!

Not really a solution, but eventually I just gave up with the HP en3700 jetdirect - it just seems very hard to get any sense out it. Eventually, I did get the webinterface working, but then it would hard lock (the web interface) if you tried to print anything via cups test page.
Switched to an Axis print server, which worked in less than 5 minutes. Why did I spend 3-4 hours on this?
Well never mind, working now.
