I don't think I've seen any external print servers support scanning functionality. Not to say they don't exist, just haven't come across any ever.
All in one printers with their own network connection are of course different ball game entirely.
That is what i mean, which is why a new printer may be the best way. I have a brother HL-3150CDW, which is a LED colour printer and to be honest it works very well, I also have a very old HP scanjet 7650 scanner and again it works well, in fact it is very fast, but if I want to copy something I need to have the computer on to do it, I have been thinking of getting an all-in-one Inkjet, the problem is inkjet have this problem with blocking up.
the Epson I linked to looks a good buy, the problem is I am not a fan of Epson printers.
I still have one of their dot Matrix in the loft and that was a good printer, but i also had one of their inkjets and to be honest it was awful, it printed well, but just kept falling apart, so I always got Canon after that.
When I used to help setup site offices, we used to play this "game" where we'd try and find the cheapest laser printer deal, that had the longest starter cartridges. Then you'd run the printer till it was empty and buy another one - not exactly ethically correct in these environmentally straightened times - but it was good bang for the back as the refill cartridges on their own could be worth more than what was paid for the the printer...
This is the problem with cheap printers, they don't last, also they are cheap because the companies hopes to make money on the ink/Toner, i think the only printers I have got Original ink for in the last 20 years is my Canon seltpy and that is because it uses a different printing system and the paper comes with the cartridge.
The toners for the brother is cheap from third parties, I use stinky ink for my ink/toners and for a set of their high-capacity toners, 3 colour and black it is £99, if i got the brother's own ones that is £290, that is one hell of a difference and to be honest I see no difference in the quality.
over the years printer manufactures have tried always to stop these third-party ink manufactures, another reason I don't like Epson, because they do it via firmware. My old Canon inkjet, I just had to take the chip of the old cartridge and placed it onto the new one, worked fine.
I like the tank idea, which Epson and canon do, buy ink in a bottle and pour it into a tank, the printers are a bit more expensive, but hopefully that also means they build them to a higher quality.
As i said above, I was thinking of getting a All-in-one, so I could use it for copying without the computer being on, also inkjets are better for photos, but i need a Scanner that is at least as good as the old HP I have got, it was an expensive scanner when new, I did not pay the price, I ordered a cheap canon scanner from Ebuyer for £30 and got a £400 one instead, I told them they sent the wrong one, but they told me they have not, so I kept it, it did say canon on the outer box. The Hp has to be about 14 years old now and still works well, which is why I don't want to spend more money.
