Hi Aaron,

Thanks for the quick reply.
It's a kind of manual installation. I will install the compiled
components first on a development machine to a specific folder.
Then I will move that specific folder to target machine and correct the
links. Please let me know if there is any problem with this procedure.

I further tried to debug it with cups error_log. Is there any such log
mechanism for HPLIP ?

It says that "prnt/backend/hp.c 675: INFO: open device failed; will
retry in 30 seconds"

Please let me know what device the backend is trying to open.

On my target system the printer will get detected as /dev/usb/lp0.

And when I say "cat file.txt > /dev/usb/lp0" , the printer prints the
contents of file.txt.

Thanks and Regards,
Narendra Babu H.C.

Your question #47351 on HPLIP changed:
https://answers.launchpad.net/hplip/+question/47351

    Status: Open => Answered

Aaron Albright proposed the following answer:
It checks by the install path of the dependency. If the deps are
installed in a non-standard area you might get an error that hp-check
doesn't detect it. However this doesn't always mean that it wont work.
If HPLIP is working correctly and as expected for you I wouldn't worry
about the hp-check error.

Hope this helps.

Aaron

Narendra,

I've seen that you've submitted several support tickets. If it's possible please email me more information about your system requirements, system you are wanting to implement HPLIP on, the number of units, the printer involved, the linux distro you are using, what company you work for (I think you work for a company?), how we can get a copy of the linux distro and the deadline you are wanting to meet.

My email is ke7ezt(at)gmail.com

If not the HPIJS solution should work better for an embedded system, however you will have printing functionality only.
