I'm setting up a print server (samba+cups) for a small office.
Printer is an HP F380 All-in-one. Linux acts as print server and give service to both windows and Linux workstations. This Box ("server") is gui-less, just CLI and ssh.

I configured also sane and hplip driver in order to the scanner works. Scanner is recognized and I can scan image throgh the tool:

What I'd really like to achieve is a headless box, so any person could just press the button "Scan" onto the HP printer and a new file would be available in a directory shared, through samba.

Does anybody know if such solution is possible?
Or there's no other way than installing a wm and rest of gui for scanning?

Thanks in advance, regards,
Matías

If anything, can't you use a bash script to automate moving the scanned image? As far as just scanning without any physical input to the system, check this following link out. I can't view it from work; I think it has to do with what you are talking about.

Thanks for your reply and link.
Really the project from the link you provided seems a similar one. Actually I don't plan to use some kind of shetfeed in order to scan a bunch of documentes automaticaly. That would be just great...

Well, today in the morning (everything seems clearer at morning...) I found this this article: http://www.linux.com/archive/feature/59138?theme=print that drived me to http://scanbuttond.sourceforge.net/

Scanbutton seems to be exactly what I was looking for. I'll take a look ant test it.

Unfortunately, both scanbuttond and KScannerbuttons doesn't seem to support the device I'm using (HP Deskjet F380 all-in-one).

I think I'd rather keep on doing some research to see if is there any other way to get if a scanner button was pressed.

Yup, that's what you need!

This is linux, it isn't easy as windows...

We use a business class HP product that allows one to send scans to a ftp server. You may need to up your scanner if you want features like you posted. I pondered this question and have no other solution.

Well I finally found a workaroung for this issue by building an external button, and connecting to RING signal of an rs-232 port.
Wrote a little program to read the status of that pin, and when it goes high (button pressed) the program trigger the scan script.

Thanks for your help and ideas fellows.

Oh nice, glad to hear you got it working man. It's been a while since I worked with any rs-232 communications; does RING have to be grounded to get signal, or am I thinking of another pin?

Hello Corp,

For me it was a long time no using rs-232 port too.
So, I chose to use RNG or DCD bits as long as they are "inputs", from modems for example. As far as I know for serial rs-232 signal levels: -12V means Low state and +12V is High state. So I only set RNG bit high when I want to trigger some action, in this case scanning a document.

So the little program I wrote is very simple, it opens a serial port defined by user, and keeps in a loop reading RING bit. When it detects that RNG went to high state it executes the script to do the scan.
My main guide researching on this topic was this book: http://www.easysw.com/~mike/serial/serial.html

If you are interested I could publish the little program (C lang.) somewhere in my blog.

That would be awesome if you could, I have a few old computers laying around with serial ports, I would actually like to do something with them.

Sure, I'll publish the little code next week, cos' we have a long weekend (Carnival) here and left the code at work. But as soon as it' published I'll let you know.

Sweet, thanks man.

Hi Josh,

Finally I published the little code and notes here in LQ's blog space:

http://www.linuxquestions.org/questi...232-port-3639/

Hope could be usefull for some applications. And sorry for the languages, both my english and C aren't "pristines".
