Specs: Windows xp
Please tell me how you connect HP 5100c to USB on laptop. Which connector did you use. The normal printer connectors dont seem to work.

That is one of those I noted when I dun a trawl at Amazon; there one or two I seem to recall.

Cable Creation and Cable Mountain also make good cables and thus in my top list for cables various as well.

It's time to surrender that antique to an electronics recycler.

There are adapters out there - usb to parallel. Amazon list one or three at least... Problem you will have is the driver for your scanner if using anything later than '98/NT?

A google trawl (search) using:

usb to parallel adapter

will bring up a few possibles; including Amazon of course...

The benefit of using Amazon as source is that you can return it within a defined time if it doesn't work.

But again you also need to find drivers for your OS (which presumably is XP)? This olde thread from CN here has references to possible source of drivers; check #3 response for a link?

and this link seems to have aa driver package that covers most of teh current OS - XP included:

HAven't used this source in the past so can't advise or comment on it.

If you try it, then ensure you install anything using manual/custom option;a NOT any proffered/default automatic.= installation. Also watch for and uncheck any pre checked boxes, other than the one for the drivers alone. That way you avoid installing who knows what besides the drivers (invariably stuff you neither need nor want; and often a PIA to eradicate afterwards). Ideally set a restore point first before you download/install too. And run a virus and malware scan afterwards...

That scanner truly is a little olde; almost an antique in IT circles; but if you can find teh drivers and a viable/compatible adapter then it may still be useable?

I know which vuescan to buy. But I have already bought a connector which doesnt work.
I need to know which type of connector works with a scanner. That is my problem.
It seems although they work for a printer they dont work for a scanner.
I have received email to select best answer but so far no one has answered my simple question.
I have also received an email from the vuescan company that they dont make one for my scanner but the link above seems to say they do.

Do you have a working driver for the scanner if using win-xp?

Have you tried compatibility mode?

If not able get it working with an adapter and win-xp, then you might get it working with win-98 as the OS?

This would mean creating a dual boot system 98/XP.

Failing the above it may be the scanner has reached the end of the road; unless you can secure an older computer with a parallel port, and running ‘98.

I just dont know why I have to repeat myself in every post. I have already provided a link for which vuescan to use. I have to get a adapter to usb. That is all my problem not which driver to use.
And if I dont have the adapter to usb then even if I have win 98 it wont help.

Your question was answered in reply #2,

Here is what Amazon has to offer:



There are more hits, these were the top three.

Further more...

An adapter is just that - an adapter.

In this case usb-parallel means that anything that uses the parallel port interface as it's source/destination will (barring unforeseen) work with it. Usually these are applied to printers and possibly some other kit; scanners included on occasion.

The proviso is that the a suitable compatible driver is also present on the computer addressing the parallel port device.

Depending on which sites(s) you visit - and believe in their content - a win-7 driver may or may not be available for that scanner model. There is conflicting information in that regard.

If you don't have the correct (compatible) and working driver installed then no adapter of any brand, quality etc. is going to work as you wish!.

I have 1995 Epson laser printer which is now obliged to run emulation mode in in some OS; as the drivers for it are not available for some of the more recent OS (be they Windows or Mac; Linux may be possible still...). It emulates an HP4 (I think).

In the past scanners on occasion could use a default generic(?) Twain driver to work with a given OS. However... many of those scanners did not go beyond the OS of the day or at best one more thereafter. I have a hand held scanner which worked fine in win-'95/'98 using twain; but nothing thereafter...

So have you found - and installed - a compatible driver for the scanner; or are you simply hoping that an adapter will do all that's required? If the latter... then I wish good luck as I seriously doubt you will succeed. Per chance you do succeed... perhaps post back with you dun it?

I can only repeat my earlier post. I have posted a link from someone who uses vuescan for my scanner. I dont know why everyone has to repeat asking me the same question if I have a driver when they ought to read my link.
Now i also posted that I have an adapter meant for a printer which doesnt work with a scanner.
Just giving me a list of printer adapters is not going to help me.
All I want is a scanner adapter that the computer should recognise it.
Is that too much to ask and so hard to understand that everyone just repeats the same.

try this post...

Might shed some light?

I found it via a google trawl using:

usb to parallel adapter for hp scanner

as the string.

Perhaps repeat the trawl I dun and go through the responses...

Failing which you may simply be out of luck, out of time with what clearly was (still is by all accounts) a decent scanner. But sadly the equipment boys want to sell newer kit and force one to dump the olde... Hence my suggestion to get a copy of '98SE and set it up as a dual boo system; or run '98SE in a VM in XP?

'98SE is about variously for pennies, even free at times...

Thanks they only say it worked for the printer. And I dont understand this is a 36 centronics mine is a 25 pin parallel. I dont have experience do they interchange.

Been a long while since I looked at a parallel port out on a computer...

I thought the computer end is 25 pin, and the other end, printer etc. Is 36... Don ‘t ask why...; I’ve no idea. I wasn’t aware the scanners used the Db25 pin input...

This link covers the issue a little

If you search for

usb to Db25 adapter for a scanner

You’ll get assorted hits; most which seem designed for printers only. Some on Amazon do make that clear. However trawling as above I found this, which might be OK, as they include scanners in their list of devices...

At least with Amazon you can test it, and if no joy you can return within 30 days?

There are one or two queries on some of the Amazon listings asking about the 5100c with such adapters; but very few answered...

ebay may also have something; but one has to be cautious as many are from China; and if they don’t work - can you return it (for free or notional cost only).

The ugreen company have written me an email saying that their Ugreen USB to Db25 IEEE 1284 Female Parallel Printer Adapter Cable FR Win 10 Mac 2m will connect the HP scanjet 5100c. Since it is not much money to layout I shall buy it and try it out and come back here.

Ugreen cables and adapters are often the first or second choice for me; Startech being the other one.

Cable Creation and Cable Mountain also make good cables and thus in my top list for cables various as well.
