### I/O Problems (Printer is not detected)

-

If the printer is not being detected by hp-setup check the following items:

Is the printer supported by HPLIP?

Is the printer powered on?

Is the printer connected correctly with the proper type of cable?

Is the printer in an error state? (i.e. out of paper, out of ink, etc.)

Is the cable (usb/parallel/ethernet) in good working condition?

USB

If you run "/usr/lib/cups/backend/hp" you should get output similar to the following:

### Functionality Problems (print, scan, fax)

-

Print

Is the printer on-line and not in an error state?

If you run hp-check -t, are there any problems reported?

In the "hp-check -t", verify that the printer is configured:

Verify in the section DISCOVERED USB DEVICES that the printer is displayed.

Verify in the section INSTALLED CUPS PRINTER QUEUES that the printer queue is displayed.

Verify on the line PPD: that the ppd file matches the printer model.

Example:
--------------------------
| DISCOVERED USB DEVICES |
--------------------------
No devices found.
---------------------------------
| INSTALLED CUPS PRINTER QUEUES |
---------------------------------
Photosmart_3300

PPD Description: HP PhotoSmart 3300 Foomatic/hpijs, hpijs 2.8.2.10 - HPLIP 2.8.2
Printer status: printer Photosmart_3300 is idle. enabled since Tue 27 May 2008 01:58:02 PM PDT

Are you able to print from any application?
View the syslog and try to print do you see any errors?
Run:

Scan

Is the printer on-line and not in an error state?
If you run hp-check -t are there any problems?
Within the "hp-check -t" output, verify that the sane is configured correctly in the SANE CONFIGURATION section. Here is an example of what you -should see after running hp-check -t:
'hpaio' in '/etc/sane.d/dll.conf'...
OK, found. SANE backend 'hpaio' is properly set up.
Checking output of 'scanimage -L'...
No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

If you do not see this or get an error, edit the dll.conf file and add hpaio. If the scanner is not detect using the scanimage be sure that the printer is supported and working correctly.

Fax

Is the printer powered on and not in an error state?
If you run hp-check -t are there any problems?
If you run hp-check -t is there a fax queue installed? You should -see output similar to the following after running hp-check -t:
