This sort of problem is difficult to diagnose. Like as not it's caused by something internal coming adrift after a long accumulation of changes:
- Windows 10 is not identical to Windows 8,7, Vista, XP, 2000, NT, W-11, or MSDOS
- 64 bit is not 100% compatible with 32 bit, and – over time – less effort is put into it.
- AutoCAD was upgraded 24 times between 1982 and 2010, and file formats like DWG followed suit
- PDF, HPGL, Postscript and other printer languages have all been repeatedly updated
- Printer technology and the necessary drivers have been changed repeatedly too.
Nothing lasts for ever, which is why software vendors recommend keeping computer systems up to date. Almost the worst thing a computer user can do is stick loyally to products well past their best-before date and then be forced into a gigantic jump when something claps out. Likely to find software doesn't work, went out of business, or doesn't understand it's own obsolete file formats. Or is incompatible with everything else on the system.
It's analogous to the way English changed over time gradually making it hard for later generations to decode. This is Chaucer:
men myght axe me why soo
I may not sleepe, and what me is.
But natheles, who aske this
Leseth his asking trewely.
Myselven can not telle why
The sothe…
At the moment the scale of the problem is unbounded. Anything from a simple tweak to catastrophically complicated.
I fear it's not a simple tweak because PDF and the Physical Printer are both refuseniks. It suggests the failure is inside AutoCAD rather than the printer or W10. The code that translates AutoCADs internal format into printable forms is in trouble. As sending random stream of bytes causes havoc, receiving software generally puts considerable effort into rejecting anything it doesn't understand. If W10 only understands PDF version 2.0 or later, it will bounce an earlier format submitted by an ancient program. Same with the print language. Coukld be the issue here.
Fortunately, vendors sometimes provide software to help customers migrate from past to future. TrueView looks good. Large organisations often get into a pickle over this: engineers warning about the risk of creeping obsolescence are often ignored by managers focussed on today money. If the poo hits the fan, it's possible to contract software vendors to sort out the mess by bespoking conversion software. Two problems: conversions are often flawed, requiring manual fixes, and expensive to buy, even by big rich company standards.
Don't give up too quickly – might be an easy fix. If all else fails, the Windows log files probably show where the failure occurs. Unfortunately, understanding logs is a specialist skill. You might start here, noting the firm profits by selling software help decode logs.
