I believe that the situation would improve drastically if you were able to show that the technology works realiably and suffiently fast for simple use cases, most importantly file search. ,

The hpijs driver, which may be the one you need, is part of HPLIP. Otherwise you might not need it unless for multi-function printers.

As for overlapping functionality: yes, hp-setup configures print queues as well, but only for HP printers of course.

Thanks Tim. Great to know that..I had no idea the defaults were also stored in the PPD itself!

Looking at the direction system-config-printer is going… and assuming I have an HP single-function printer, why would I need HPLIP? Is HPLIP mainly targeted for multi-functional printers ? is that about it? Is there overlapping functionality between the two?

Regards,
Jorge

Jorge: yes, that’s exactly how it works. The defaults are stored in the PPD itself (/etc/cups/ppd/) by cupsd.

Hello Tim,

I just found out your blog while doing some search on CUPS. I’m a Fedora user and I’m learning the basics on how the printing system actually works. These screenshots are awesome!

On the printer properties screenshots: I’m curious about the “Printer Options” section. Are these options on the GUI created on the fly by reading the printer’s PPD file so that it’s actually showing the printer’ SPECIFIC options ?

If so, whenever I change something there, where are these preferences stored? Is it somewhere on the filesystem under /etc/cups or are these options sent directly to the printer itself and stored in its internal memory?

All the best,
Jorge

Hi Hellen, It sounds like a problem with the driver being used for that printer. Please report a bug to the people who put your operation system together.

Ok, today I discussed this with Kees Cook (Ubuntu security team lead) and Martin Pitt (former Ubuntu security lead, current desktop team lead).

They made the point that PolicyKit authentication alerts and Seahorse authentication alerts both open as normal dialogs, without opening preliminary notification bubbles first, and without even grabbing keyboard and mouse focus. So if there are cases where the window manager allows focus stealing while you are typing your password, that should be fixed consistently in the window manager, rather than in different ways by system-config-printer and other Gnome components.

mpt: the reason that won’t work in this case is that it is a password dialog, so grabs keyboard and mouse focus. It does this, in turn, to avoid some *other* dialog from accidentally getting our password if it pops up at the wrong time. (Other password dialogs also do this.)

I’d love to know a definitely answer for whether this is really necessary, and to have all the various password dialogs behave in the same way.
