HP Laserjet 1100 and HP Laserjet 1100A as compatible models but does not make mention of P1102

HP 1102 is a different model than 1100A, good solution for this is open-wrt (gargoyle) on router.

well, I contacted Tp-Link support and they also said most probably P1102 won't work with 842ND as it is not in the compatibility list, but I may do a trial to see if it works.

Anyways, I proceeded with the purchase and happy to tell that my HP Laserjet Pro P1102 (model CE651A) http://www8.hp.com/sg/en/products/printers/product-detail.html?oid=4110395
works great with TL-WR842ND multi-function router. My configuration was as follows:-
a. Windows 7 64-bits
b. Firmware upgraded to latest version (130110)
c. Latest version of USB Printer Controller Utility downloaded from Tp-Link website

UP...

there was a lil problem that I encountered. I would like to share it for benefit of others

The installation on my laptop went without any issue (Win 7, 64-bits Avast Free Antivirus)
When I tried installing on my Desktop PC, the installation went fine but the USB Printer Controller was unable to locate the printer... i reinstalled the printer drivers as well as the Print server configuration utility but to no avail... I noticed that a device named "Kernel USB Software Bus by TCP" under Devices and Printers (Control Panel) was missing while it was there in my laptop. I also noticed that everytime I tried to connect, the AVG antivirus would warn me that Printer utility is trying to connect to internet.... So I concluded that the AVG is messing up something.... instead of trying to add some exception rule, I un-installed the AVG and installed Avest...and everything worked fine :)

There is no mention of this Kernel device in the Tp-Link documentation. I think they should include some warning about anti-virus and the Kernel USB software bus by TCP

Nice sharing...

Hi, i have recently bought Tp-link w8968 ADSL router. It has a USB port for printer sharing and file sharing. I have a printer which i want to connect with my network. Printer is HP Laserjet Professional P1102(Non-wireless). When i plug the printer into the router, the Tplink Usb controller shows that this printer is connected but after 5-8 seconds printer disappear from the list. I have multiple attempts to overcome this issue but till now i am not able to find any solution for it. Please help to get out of this problem. I really like this printer thats why i am keen to install it on my network. Thanks in advance.

The compatible list of the ADSL router: http://www.tp-link.com/common/compatible/print-server/ but I don't know wether your printer is in this list.
