DLINK DP-300U. Desktop shows printer offline, Laptop prints OK.

ok have you tried changing the settings in the print server usually a printer must be configured on the print server before it can be used if it is on the network try telneting in to it through a web browser like you may a modem

kindly go thru this website
ftp://ftp.dlink.co.uk/dp_print_servers/dp-300u/dp-300U_manual.pdf

Hope this helps. Please rate my response.
Thanks.
Have a good day.

Just here D-Link - TechSupport FAQ

Your type of d-link the highest version is 1.20 which can be downloaded from ftp://ftp.dlink.com/Printserver/dp300U/Firmware/dp300u_firmware_120.bin and updated on your d-link administrator page.

here is the user manual for the DLINK
http://www.givemefile.net/manuals/printing_server/d-link/file/33217.html

also this is the link for the printer

http://h10025.www1.hp.com/ewfrf/wc/product?product=1814094&lc=en&cc=us&dlc=en&lang=en&cc=us

here is the link you need to go to ftp://files.dlink.com.au/products/DP-300U/Manuals/DP-300U_Manual.pdf

Have a pleasant day.

dont' worry about what the d-link site says. its because they haven't tested it. i got my dp-301u to work fine with my hp1020 on 2 different workstations with the following steps.

1. install printer locally via usb and test.
2. create a second printer as per the dlink manual creating a port. don't worry about the name as we will delete it.
3. once created go into the properties of the 2nd printer and change the port to something local - anything will do to free up the port.
4. go into the properties of the printer that was created in step 1. and change the port to that of the print server.
5. test print. should work fine.

cheers!!

I connected my HP5MP to the DP-300U LPT1 port.
I configured my port on the DLink Configuration tab, giving it a name "hp5"
...The default login is at http://192.168.0.10/ user:admin pass:(there is no pass by default)

On my Mac, I go to System Preferences > Print & Fax
Click the + to add a new printer
Select the IP option
Choose the Protocol: Line Printer Daemon - LPD
Type in the Address: 192.168.0.10
Type in the Queue: hp5
Print Using: Generic PostScript Printer or better yet, 'Select a driver to use...'
and find the driver for your HP LaserJet 5MP.
Save it. Works like magic. ;-)

If you change the IP address or password on the DLink, just CYA and write it all down on a sticky note then tape the note under the DLink chassis. There's no reset button on the thing, and if you're o a Mac, you won't necessarily have access to the Windows utility to jack with the DP-300U. So, write it down, kidd-o!

DP-300U Print Server is not compatible with Sharp AR-5320. Pls check D-Link website on the list of compatible printer. For USB Print Server that is compatible with Sharp AR-5320 try Intellinet.

What is the IP of the Print Server and the Printer itself? They have to be on a 'flat network' or the gateways of the the 'adjacent' networks have to be defined as a neighborhood.
