I see that the Kodak Hero 5.1 gets repeated good reports, is cheap to run, has duplex and wireless capability and is available for about £70, Local friends bought one and swear by it

Got rid of HP and Brother and just got an Epson (for A3 and ADF, plus a Canon for photos)!

I suppose you have to go with what you find.

HP produce some fine printers, but the software is rubbish. That's why I dumped the eventually, after more than ten years and four printers.

Just a small clutch at a straw for your scanning problem.

Many all in ones are flaky when scanning wirelessly.

If you haven't tried it hard wired give it a whirl.

Never used Paperport, though I've had it bundled.

I usually scan straight into Word, using "Insert image from scanner".

This presupposes you have Word of course, and is expensive on storage space, but I have an big old redundant hard drive in an external case just for docs.

Perhaps not going to help you with the PaperPort issue, but I have a range of multifunction printer's, including a HP OfficeJet which must be nearly 14 years old (possibly older) and still working well.

HP support isn't as good as it was, but that possibly just my opinion over a recent problem?.

My recent purchases have been WiFi Canon (Argos) and HP (Staples) printer's, because they were very cheap on special offer. But have you considered Brother, because I have a DCP-135C that seems to tick all the boxes ( It came with a 1 year warranty, but on registration Brother added 2 more years for free).
