I have an HP 7612 True A3 AIO printer. Works very well and compatible cartridges are much cheaper than HP ones.
Not sure about the booklet situation however as never needed this, but it does have a check box in the driver to select booklet.
Donald Trump would have been far too scary.
I think contactless is great. I can’t remember how many times I left my card in the chip and pin machine and only realised later resulting in another 12 mile trip to the local town to reclaim it. Chip and Pin required that the card ceased to always be in your hand thus was forgotten about when packing purchases. With contactless the card stays in your hand and is never forgotten. Wish the spending limit was higher though.
Seems to me that he was probably the manager of the men’s team in waiting. I have found the women’s game to be far more entertaining than the men’s game. This is political correctness gone mad. It is about time that some new strategies were injected into the men’s game to prevent us all from getting bored with the continual failure to live up to expectations. At least the women’s team excelled in that.
Mark for England is my feeling and never mind the old brigade who are still living in the past.
Tom at Piriform has posted this which contradicts the info that you have posted regarding update.
Hi all,
The only version affected is the 32-bit binary of CCleaner v5.33.6162. It was the application that was the issue, not the installer. If you’re using a 64-bit version of CCleaner, then you’re unaffected although we recommend updating to the latest version. There is also no effect to the Mac or Android versions.
At this time, we won’t be releasing a detection tool as the issue was in CCleaner itself, so uninstalling or updating the software removes the risk. You can download directly for free from here: http://www.piriform.com/ccleaner/download/standard
For those interested, the MD5 hash of the affected CCleaner.exe is: ef694b89ad7addb9a16bb6f26f1efaf7
Thanks – Tom
Tried several 192.168 addresses in Firefox without ant problem
Installed on 10 machines , no problems.
Have you set your “Active Hours” which is the time that Updates will not activate and so avoid the problem you describe.
There are also several programs available which will disable auto updates.
Thanks, it brings back memories for me too.
Same here Jukebox. Can’t see it at all.
Sorry didn’t see that you had sorted it as never saw Page 2.

These work OK for me
Some good news at last.\shame most originate in India.
Yes I remember that too. Fluidics were reliant on surface tension and stiction. We constructed logic circuits using them. At the time their potential was in fire risk locations in the petro chemical industries. I guess it never really materialised as the inherent problem was that they were much slower than conventional electronic gates etc.
Powershell is much more powerful and you need to learn the syntax. If you want to revert then:-
Go to Taskbar Settings (Right click a blank area on the Taskbar). Select Taskbar Settings and move the option “Replace Command Prompt with Power Shell to No.
Oh and Mr Kirchoff drove me loopy for a second with his law ?
If In remember he postulated 2 laws.
At any node the sum of currents in equals the sum of currents out.
In an circuit the EMF (Applied voltage) equals the sum of the individual potential differences in the circuit components.
.
Common sense really as you can’t just lose voltages or currents.
Hey I finished college in 1972 at the ripe old age of 30 so it is digging up issues I have not had to look at for over 40 years but then again the basics never leave you once fully understood. It is the detail which eludes me now. I used to love circuit analysis in real time using Laplace transforms on servo mechanisms but now I can only just remember what a Laplace transform is, never mind how to manipulate the maths of it. There again at 73 and retired I no longer need to do so but it is nice to know that if needed I could go back and use them I have the capability to do so. Lets hope never.
About the only thing you could perhaps have emphasized is that obviously the ‘sound’ being amplified consists of many different frequencies so if the impedences are not matched then some frequencies will get boosted and others muted so giving an overall lower sound quality.
Quite correct, I should have summed it up with this conclusion.
I like the explanation in the link by JayCeeDee but thought it a bit too technical for Tadka who professes to be non technical in this area.
This is an extremely complicated subject and difficult to explain to a non-electronic person. Basically the rule is that the impedance of the headphones must match the output impedance of the amplifier it is plugged into. Unless this is met then the maximum power transfer does not occur. Any mismatch results in a reduction in power transfer.
There is a further complication. Resistance (ohms) is the relationship between the voltage applied and the current (amps) that flow through the circuit. The relaionship is expressed mathematically as Resistance(R in Ohms) equals Voltage divided by Current or R=V/I where I represents current in Amps.
If a voltage is applied to a purely resistive circuit then this relationship holds true. This rarely the case however as most circuits involve the use of inductance (L in Henries) which is associated with a coil or magnetic effect and Capacitance (C in Farads) which is associated with electricity storage between conductive surfaces separated by an insulating material.
In these circuits the reactance (equivalent of resistance) varies depending on the frequency. Reactance increases with frequency in an inductive circuit and decreases in capacitive circuits ie the opposite effect. Most circuits comprise components containing inductance and capacitance, so the circuit as a whole is frequency dependent, Impedance (Z) is again the overall equivalent of resistance when the circuit contains inductance and/or capacitance and is therefore frequency dependent.
Applying this to the question, the output impedance of the amplifier must match the input impedance of the load circuit for maximum power transfer. Any mismatch therefore has varying effects depending on the frequency which could result in progressive loss of higher or lower frequencies depending whether the load is inductive or capacitive.
In this case the possible resistive mismatch could be causing the loss of volume and the possible loss of high frequency by an impedance mismatch.
Unfortunately Tadka does not give the output impedance spec of the amplifier so it is not possible to give a definitive answer bearing in mind that headphones have impedances ranging from as little as 8 ohms and he is using 250 ohm headphones.
Impedance matching is important as if the mismatch is large, then the power dissipated in the output device (which should have been transferred to the load device) can rise above its rating causing overheating and eventual burn out failure.
This is a very simplistic explanation to explain the basic idea behind the situation and I appreciate it hard for a non electrical engineer to fully comprehend.
