Comment 8 for bug 597612

Since July 8th I made some tests and investigations. Here You see what I discovered:

(Please, consider here below I'm translating from Italian to English all the system messages and buttons or menu descriptions.)

1) Every time I access to the menu "system > admin > printing" I've got a crash - see for example the last event today (I attach here a TGZ archive).

2a) When I select "test print" from the control panel, I get the correct typical ubuntu test-page (grayscale images, ubuntu logo, ...).

2b) When I select "automatic test print" (I suppose this means to use the internal test page procedure of the printer), then I got an error message: "CUPS server error: an error happened during CUPS operation: <<client-error-document-format-not-supported>>

3a) When right-click on to the printer icon from the "system > admin > printing" menu, and selecting "show printing queue" I only obtain an empty window even if I select "show completed jobs". This leads always to a crash.

3b) When I click on to the printer queue icon in the notification area I obtain the real queue window, where all the running or completed jobs are displayed.

4a) The printer fails always to print some kind of documents, for instance large PDF files which include images. I saw this error log message:
/var/log/daemon.log:
Jul 14 08:44:19 uffcom2 hp[9036]: io/hpmud/musb.c 1403: unable to write data hp:/usb/hp_LaserJet_1320_series?serial=00CNRW66G0LB: 45 second io timeout

4b) I reported this event to bug #595650 - somebody supposed that my printer runs out of memory. Could it be? If yes, how to fix this problem?
