I have a desktop that is connected to my wireless router via LAN cable (router has 4 LAN sockets).
Also have an Epson R300 printer currently connected to desktop via USB.
To print from my laptop I have to have the Desktop turned on.
What I want to do is be able to just turn printer on and print from lappy without using Desktop PC.
I see lots of wireless print servers for sale but I was wondering if I can just get something that can connect the Wireless Router to the Printer, cutting out the Desktop.
I am not overly good with machinery so am not at all sure if this is possible.
Thanks
I still remember having to write your own code in FORTRAN rather than be a cut and paste merchant being pampered by colour coded Intellisense - ahh proper programming - those were the days

If the printer has an ethernet socket you will be able to connect to the router and print in that way.
Doing this would entail setting up a wireless network - which all I can suggest is that you google this area, as wireless networks are notorious for being either really easy or really hard to set up.
Why not install the printer on your laptop and just plug the usb cable into your laptop?
You always pass failure on the way to success.

Unless your network has a ethernet port, you have to use a print server. I use a Keyspan PS-4 - it supports up to four USB (2.0) printers.
It seems to work fine under windows, but there's no Linux support.

My boss reported good results with a Netgear WGPS606. We've just bought one for the office, although we're actually only using it as a wireless bridge for our Ethernet-capable printer after relocating it to a location that doesn't have ready wired access.
Come to think of it though I think you're asking for a wired print server[^].

HI 
I am a college student doing an ICT course which involves a unit on hardware.
When i was starting the course i heard some comments about what was better, AMD or Intel. So i was just wondering what people on here thought.
Is an Intel processor better than an AMD processor or does it depend on the users needs?
thanks for reading

AMD vs Intel
Both Intel and AMD offer a wide range of CPUs. The two companies' products are in direct competition and are both capable of running any current PC software. The differences are in technical details that, although they may be used for marketing, don't necessarily mean much to the end user.
Pricing is also very competitive, with AMD's products being generally cheaper than comparable Intel models. At the budget end of the market, Intel's offering is the Celeron which is a cut-down version of the Pentium 4. AMD's budget processor, the Duron, is still available although it's getting harder to find.
In the mainstream desktop market it's Intel's Pentium 4 versus AMD's Athlon XP and Athlon 64. The chief difference between the two is that the Pentium 4 and Athlon XP are 32bit CPUs, while the Athlon 64 is a 64bit model (see later on for an explanation).
Just recently both companies have launched new ranges of processors, Intel with the Extreme Edition of the Pentium 4, an expensive model for the hardcore gaming market, and a new version of the Pentium 4 processor. You might see this referred to as Prescott to differentiate it from the previous Northwood version. The technical differences aren't huge, but the pricing hasn't changed for models at the same clock speed. So if you're given a choice, ask for the Prescott models.
AMD has also introduced the Athlon 64 FX range, a high-end gaming/workstation CPU that prompted Intel to launch the Pentium 4 Extreme Edition.

Best of luck doing your BTEC. I assume from your age (your biography) this is your first year of post 16 education. Enjoy this next two years but ensure that your assignments comprehensively cover what is needed (in other words, strive for Distinction grades) and submit them on-time. Don't be afraid to ask questions here at Code Project but when you ask questions, don't ask for people to do your work for you, and show that when you ask questions you have made an attempt to answer them yourself. And if you require advice on resources such as books and tutorials, then ask.

Thanks everyone for you help, i wasn't trying to pass it off as my own i just forgot to put in it speech marks  sorry if that offended people.
and
yes i have just started college, i'm aiming for Distinctions all way through. I need 2 distinctions and a merit to get into university, where hopefully i will study Computer Science and AI.
Thanks

I've always preferred Intel. In the Pentium II and III days Intel typically had a clear lead, but were usually more expensive. AMD started to pick up a performance lead towards the end of this era. However, I tended to observe that the computers using VIA and SIS chipsets were less reliable than Intel chipsets. When all the processors used Socket 7 (Pentium and AMD K5/K6) you could match an AMD processor to an Intel chipset; once Intel moved to Slot 1 for the Pentium II and the AMD clock rates started climbing, the old Intel chipsets couldn't cope any more leaving VIA and SIS as the only (flaky) choices.
It could be that the behaviour of some of the owners of the computers was actually the cause of the flakiness - generally they'd swap components over regularly and install and uninstall a lot of (often slightly dodgy) software. Still, people with Intel systems did the same and they were generally more reliable.
Pentium 4 - NetBurst architecture - was an attempt by Intel to massively ramp the clockspeed and it was designed to make best use of fast clocks, by having a long pipeline in which a little progress was made in each stage. If you're not familiar with electronics, it takes a certain amount of time for the signal at the output of a series of logic gates to stabilise at the correct result, or in the case of latch circuits, to latch at the correct result. If the result is sampled too soon (with a faster clock), the incorrect result can be latched and you get incorrect answers.
To get the most benefit from this, though, the pipeline needed to be kept filled, and instruction dependencies, memory latency, and branch mispredictions tended to mean that it couldn't be kept full, meaning cycles were wasted. In the case of a dependency error or branch misprediction the whole pipeline has to be thrown away and restarted to recompute the correct operations.
The trouble is, the design was intended to ramp to 10GHz and as we know, we never got there - 'NetBurst' Xeons topped out at 3.8GHz or so. The problem was simply heat - too much current was leaking, causing the circuit to consume more power and emit it as heat rather than do useful work. AMD, on the other hand, kept a shorter pipeline consistent with its older models, with larger amounts of work done per cycle. In the end the Athlons were able to clock high enough to surpass the P4s at much lower clock rates.
At this point the choice of chipsets for an AMD system appeared to be VIA, nVidia or ATI. nVidia and ATI can't get a video board right (I use whichever the computer manufacturer chooses because they're equally bad) so I hold out no hope they can get a chipset right, even if the memory controller is now part of the processor package.
Meanwhile Intel were effectively still developing the Pentium III for laptops - as the Pentium M - as the NetBurst architecture was utterly wrong: the power characteristics would only be suitable for 'desktop replacement' laptops that were only moved from place to place, as the P4 would flatten virtually any battery in minutes. Towards the end of the P4's life it was clear that the Pentium M was actually faster, not just clock-for-clock but overall, and you saw a few desktop boards. Result, a massive about-face, and the new desktop processors eventually christened 'Core 2' were a derivative of the Pentium M (Virtual PC 2007 still identifies my Core 2 Duo T7200 laptop as an 'Intel Pentium III class'). It's reasonably clear that Intel have taken back the performance lead.
There's a bit of back-and-forth over different Single-Instruction-Multiple-Data instruction sets (MMX, 3DNow!, SSE, SSE2, SSE3, SSE4 I think is in the works) but on the whole, and despite much encouragement from Intel, I think most code still uses the antique x87 FPU instructions for floating-point operations. The NX (No eXecute) bit added by AMD in the Athlon 64/Opteron has been adopted by Intel (as eXecute Disable, XD); both are now offering incompatible virtualization support, but Virtual Server 2005 R2 SP1 supports both types and I think VMWare supports both as well. AMD invented 64-bit extensions to x86 and after a bit of arguing, Intel adopted them as well (with a few minor omissions and differences, but there's enough common ground to write an OS to).
Intel's own attempt at a next-generation 64-bit architecture is much more elegant (you don't get much less elegant than bodging 64-bit extensions onto a 32-bit architecture that was itself already a bodge of a bodged 16-bit architecture - 8086 was crap from day one) but bizarrely has been stuck at low clock speeds - while it might be much more efficient clock-for-clock than x86, Core 2 (Xeon 51xx, 53xx) and Opteron are faster overall because they have faster clocks. They're also a heck of a lot cheaper. It's no wonder Itanium didn't take off (it didn't help that the built-in x86 emulation was woefully slow).

I am thinking of purchasing a Toshiba Notebook (A215-S4757). However, I am not so sure about AMD. I will be using the laptop for Software Development. I was wondering if would face any trouble with this processor or should I simply go with Intel Centrino??

There shouldn't be any major problems, but Intel's led AMD in the performance/watt metric for mobile chips for years. Not a problem if you're working plugged in, but it'll drain your battery faster while working mobilely.

Do you think that AMD would be able to sell CPU's if there was ANY hint of incompatibility with Intel CPUs?

I used WMI's win32_physicalmemory to get it, but it's empty.
Would anyone give me help?
Thanks!

That's because the manufacturer of various components, like motherboards, has to supply a WMI Provider that exposes all this information to WMI. Normally, you get this from the manufacturer and install it. Since you don't have a provider, or the manufacturer hasnt written one (there is nothing that says they have to!), you can't get the specific information. Also, even if the manufacturer provides a WMI Provider, there is nothing that says they have to provide ALL the information WMI can handle. Most of the time, they just provide a smalle subset of the total information in the WIM classes.

I knew there is a guy from Russia that he wrote a small program, the program can read/write SPD information of the memory, since the manufacturer of the memory was saved in SPD of the memory. anyone can search the program on Google.
I thought that can read/write I/O directly to fetch SPD information of the memory, a solution is using GiveIO.sys (Google it!) do it. But I don't know which port is corresponding to the SPD reading/writing, On other hand, if that got the SPD info. we still need to translate the SPD info, maybe a mapping table for this.
As above mentioned, I may want to disassemble that SPD program written by Russain guy..

Maybe your machine doesn't have any memory.

or the memory is not very good at remembering its manufacturer.

Hi All,
I am writing an application which checks LPT signal for doing something. My code looks like:
void LPTThread()
{
while (1)
{
if (ReadLPT(pinX) = signal level Y) {do something;}
}
//pin is one of pins of LPT port
//signal level of each pin is 0 or 1 at a time
}
This loop cause the CPU usage always 100%, is there any way to prevent it? Can we catch this change by any event handler, it mean when a change occurs at LPT or, this event handler will be called?
Thank you for your help.
(I have already put this message in the C++ forum first but then I find this should be put in this forum)

Hi,
I don't know about any LPT event; I would suggest you put a delay in your while loop
to reduce the CPU load it generates.
Sleep(1000); would reduce your checking to no more than once a millisecond
(probably once every 16 to 20 msec, see my timers article), and reduce the CPU load drastically.

Thanks for your reply.
My problem is the application must be sure that when LPT signal change, the application will handle it immediately, so that I cannot let my thread sleeps.
