When I choose hp_no_device_found, the job in the print queue does not disappear after sometime. When I choose LPT1, the job disappears after sometime. Almost looks as if it sent the job to the printer and then removed itself from the queue. In any case, since Windows detected it on LPT1, I put it on LPT1.
From the link you provided:
No known autodetection signatures.
So that's why it didn't detect my printer and I had to manually specify it. The driver mentioned on the page is the same driver Ubuntu chose when I click on HP Deskjet 695C.
Also, when I type
ps -e in a terminal, I see
cupsd running.
The printer simply won't do anything when you send any print job. Any other option?
EDIT: When I go to:
http://localhost:631/jobs?which_jobs=completed
I see several jobs I assigned as "Completed" while none of them actually printed.
