|Who made the "Particle Size Analyzer" ?. |
If they're still in business, you may be able to get many of the answers you need from their web site, if they have a web site, or by contacting them via email. They may even have software for the same "Particle Size Analyzer" model that runs in XP (or 2000 - most programs for 2000 run in XP fine).

"came with a Compaq computer (DOS 5.0, Win3.1)"
Then you can use Interlink-like programs to connect that computer in Win 3.1, or Dos, to another computer. It's usually much easier to use such programs in Win 3.1.
"Do you know if I used a laplink program..."
You would need to use either the (or an, if there is more than one) obsolete Laplink version for Dos, or the (or an) obsolete Laplink version for Win 3.1, and you would have to dig around on the web to find out how to use the program and how to connect to a computer with a newer operating system.
The Laplink web site does not support those versions anymore, and there seems to be no info about them when you search their knowledge base, despite the text saying there is info about older versions there.
You would probably have to use a "dos box" or "dos virtual machine" program or similar on the XP (2000 or higher) computer
I recommend you use something that is supported NOW , instead, so you at least can look for support on their site, or contact them.
E.g. Total Commander - see the last part of response 3 above.
"If I am connecting on a parallel port (what was the printer port) do I just "print screen' to get it to send to the newer computer via the link?"
I don't think that's possible. Print Screen only works on the computer it is executed on as far as I have gathered. It only prints what is visible on the screen in any case.
You could use a screen capture program of some sort, meant to be used in Dos or Win 3.1, to make a picture file (*.jpg, or *.bmp, etc., etc.) of the results, transfer that file to the other computer and print it no problem, if you can find one - that probably can only capture what is on the screen, or blocks of what is on the screen, too. E.g. I use PrintKey, but as far as I know it works only in Win 95 and up.
There MAY be old versions still available on the web - more likely for Win 3.1 than for Dos only.
Can you run this program in Win 3.1 ?
Or, if you can run the program in Win 3.1, as I recall, you can copy the screen contents to the Clipboard in Win 3.1 (you just press Print Screen ?) , then go to the Clipboard and save it as a*.bmp file or possibly other types of picture files.
You could establish a network between the computers and set up a virtual printer on one or the other computer - that would be easiest to do if you had Windows for Workgroups (Win 3.11) rather than Win 3.1. Support for Win 3.11 and it's added features was very well supported in Win 95 and up. It's probably possible to do that with Dos and Win 3.1 too, but much more complicated.
You can use a PCI parallel port card in the Dos computer, if it has a spare PCI slot, if Dos drivers are available for it (more likely if it's a used card) or an ISA enhanced parallel port card, or more likely an ISA multi-I/O card that has an enhanced parallel port built into it (usually you can disable everything except what you want to use) , if you need the printer connected to the Dos computer as well.
(Enhanced = supports EPP, ECP, or EPP/ECP mode - most printers must use one of those modes. Most ISA cards with parallel ports do NOT support Enhanced modes - only the ones made later do. All PCI parallel port cards I know of support enhanced modes. )
You MAY be able to simply choose to Print to a file, then copy or move that file via the parallel connection, then print that file on the other computer that has a printer connected to it. If you can do that, the file must be saved in a format that the printer can interpret properly.
If it's a dot matrix printer, 2000 and above have the drivers for many common brands and models built in, but the printer is NOT Plug and Play detectable, so you must manually select the model in Printers and Faxes - Add a printer.
If it's not a dot matrix printer, the same thing applies for most parallel connected printer models, but not all brands and models common when the computer was new are supported in XP.
E.g. If the printer is an old Canon BJ or BJC model, XP has the software ("drivers") for those built in. If it is an old Epson model, XP is likely to have the support built in. If it's an old Citizen model, it probably doesn't.
