CUPS upstream dropped the CUPS broadcasting/browsing mechanism to automatically
discover shared remote printers beginning from 1.6.x. Replacement is
Bonjour-based broadcasting odf the shared printers by CUPS and on the client
side the application's print dialogs are responsible for browsing these
broadcasts and listing the remote printers appropriately. CUPS even provides a
library function for that now.
See
https://blueprints.launchpad.net/ubuntu/+spec/desktop-r-cups-bonjour-browsing
I wrote there:
----------
The CUPS Browsing/Broadcasting mechanism which made print queues shared on
remote CUPS servers automatically visible for the local CUPS daemon and so for
local applications got dropped upstream from CUPS 1.6.x on. Ubpstream has
replaced this functionality by Bonjour-based broadcasting (under Linux
implemented via Avahi), an OS-indpendent PWG (Printing Working Group) standard,
but this lacks the implementation of browsing on the client side making the
printers on remote CUPS servers not automatically appearing any more.
Ubuntu Quantal's CUPS has a mega patch to forward-port this functionality from
the old CUPS for one cycle, to avoid regressions. We cannot carry such a patch
eternally, and we should follow upstream and the PWG standards.
So in Ubuntu Raring we need the real solution which means that the print
dialogs (upstream-recommended solution) or the CUPS daemon (how I like to have
it) takes the new Bonjour (Avahi) broadcasts to display the shared remote CUPS
queues automatically. The browsing functionality is implemented in the CUPS
library (libcups) from CUPS 1.6.x on, but there is currently no production code
using these functions.
Upstream expects the print dialogs to use the new library functions for
displaying the new queues. This would require modifications and upstream
submissions for GTK, Qt, and LibreOffice at least and this does not safely
cover all existing applications which have CUPS-aware print dialogs and
therefore listed the remote queues before. Especially printing from the command
line would not be covered.
The better approach would be modifying the CUPS daemon so that it uses the new
library function to find the remote queues and advertize them like its own
local queues. Where the CUPS daemon needs to be patched for that we could
probably derive from Quantal's CUPS Broadcasting/Browsing forward port patch.
The new Bonjour browsing patch being based on the new standard way of Bonjour
broadcasting has probably good chances to be accepted upstream.
This feature does not only prevent a regression, but it also helps to more
easily access printers connected to Mac OS X machines (they broadcasted
Bonjour-only all the time) and also for mobile Ubuntu devices. Usually you do
not have connected printers to tablets or phones and you carry them around
between different local networks, so here it is especially important that they
automatically pick up the print queues in the local network.
----------
Such a patch to the CUPS daemon or an extra daemon to do the browsing and
add/remove queues appropriately in the local CUPS environment is also not the
best solution but a way to avoid regressions with legacy apps.
The real intention from upstream is that all print dialogs browse the print
queues available on the local network via Bonjour (under Linux implemented by
Avahi), where print queues on the local network are CUPS queues from Linux and
Mac OS X but also IPP printers which broadcast themselves via Bonjour (IPP
Everywhere printers). Printing on iOS devices (iPhone, iPad, iPod Touch)
already works this way. These devices do not allow the setup of local queues at
all and they discovcer available print queues via Bonjour.
For this the CUPS library has even special functions, see as sample code the
program
cups/testcups.c
to be called as follows:
cups/testcups enum 1
"enum" makes it enumerating printers and the number is the number of seconds to
Bonjour-browse for network printers.
The library function is the function cupsEnumDests() in cups/dest.c. For
Bonjour browsing it must be called with a non-zero value for the msec
parameter.
This feature in the print dialogs is VERY urgent because:
- This is how CUPS upstream and also the PWG (Printing Working Group,
http://www.pwg.org/) expects how network printing with automatic
queue discovery works.
- This is less resource-consuming on mobile devices which do not have
local print queues. avahi-daemon is running anyway and the CUPS
daemon does not need to be running when there are no local queues.
- CUPS upstream would not most probably not accept patches on the CUPS
daemon to browse for Bonjour-advertized queues and let them appear
like local queues. |
Buy Cialis Online to Handle Sexual Problems Effectively:-
At some stage in a man’s life, he might experience difficulty in achieving or maintaining a firm erection. These erection problems happen when a man is not able to achieve or sustain an erection, which is firm enough to engage in sexual activity. For the majority of men, this problem takes place occasionally and is not considered a serious issue. Nevertheless, if you are not able to get erection one-quarter of the time or even more, you might have a medical problem that needs instant attention of a doctor. These erection problems are also referred to as impotence and sexual dysfunction. But, there is absolutely no need to get anxious, as there are various drugs to treat erectile dysfunction effectively.
Cialis is an approved medicine, which is used by men to handle their erectile dysfunction, and what’s more, you can buy Cialis 20mg online as well.
Visit:- https://bit.ly/2EJsYyo
How Cialis Operates?
Cialis is also dubbed as ‘Weekender Pill’ because it can easily last up to 32-36 hours. Therefore, the overall effects of the drug will be more intense and long-lasting. It has been observed that many men prefer Cialis over Levitra (Vardenafil) and Viagra (Sildenafil) because both levitra and viagra usually last up to 6-8 hours. After taking cialis, the effects of the medicine set in as quickly as thirty minutes and average time to take full effect is two hours.
Important Facts About Cialis:-
Generally, the doctors inform patients that significant consumption of alcoholic beverages (5 units or more) with cialis could increase the possibility for side effects. Moreover, the physicians also recommend not taking more than 1 dose in a 24-hour period. People taking cialis can eat food normally, however it is worth mentioning grapefruit or grapefruit juice can perhaps affect the overall absorption of cialis, which includes an active ingredient, tadalafil.
Visit:- https://bit.ly/2EJsYyo
Dose Administration:-
The drug is easily available in 2.5mg, 5mg, 10mg and 20mg. Usually, the starting dosage is 10mg as required before sexual activity, but it would also depend on the person. The medicine has demonstrated to improve erection in men, when compared to placebo. Based on tolerability and effectiveness, the doctor might suggest an increase to 10-20mg or a reduction to 5mg. Moreover, when the medicine is taken daily, the initial dose is 2.5mg, which should be consumed at the same time daily, without considering the timing of sexual activity.
With so much to acquire from Cialis, it would be wise to get in touch with a doctor, discuss your erectile problems, and Buy Cialis Online in USA. |
