OK -- All the following is typed "on the fly" - not great - here we are...
Take from it what you will -- or ignore the lot.
OR
Go out and find, obtain, purchase OCR software and be done with all of it.
Start...
If your OCR is listed Programs and Features as OCR software,
Then
Your Operating System is some flavor of Windows that supports the full driver and the Universal Scan software
And
The listing Programs and Features is likely referring to the software linked to the HP Universal Scan and not the original HP Scan that is part of the full driver printer software.
No, I cannot explain why the HP Scan name ended up the same (although at least the shortcuts on the Desktop can still distinguish which app / software is which). Perhaps the naming tangle is the result of a clever programmer joke... It's been interesting trying to explain the names and where / how they are used. I'm not even sure at this point whether I'm even correct in my assessment of the situation.
Worse, the Printer Assistant has been removed from some full driver printer software packages -- this is fine, the Printer Assistant has no place in the new Full Driver software. That said, it's a mess explaining the sudden change to those who have used HP products for a number of years and perhaps even used and liked the Printer Assistant.
Meh.

Neither can I explain why -- presuming the OCR refers to HP Universal Scan / HP Scan named shortcut on the Desktop -- the software would not include the OCR line in in Shortcuts for OCR .
Note
I cannot untangle HP+ service (OfficeJet Pro 9135e) to test whether the following is true.
The "Guess" - What appears to be true...
HP+ has altered the software - OCR is no longer (was perhaps never??) part of the installed HP Universal Scan software for the new printer (OfficeJet Pro 9135e) .
HP+ has altered the software?? OCR is not part of the HP Scan software that is part of the Full Feature Software.
The HP Universal Software -- when pointing at the HP+ enabled HP OfficeJet Pro 9135e -- does not include the OCR shortcut.
AND
When I select the Envy 7855 (Settings gear on the top row), the OCR Settings is displayed as part of the list of Shortcuts.

Conversely -- and perhaps partly because I've enabled HP+ ? -- HP Smart Shortcuts always include the various (extra) File types in the Shortcut edit / create dialog.
What does this mean for you??
Perhaps nothing and I cannot test for you -- my HP+ printer and Not-HP+ printer setup appears to be a migrated mixture of "there" and "not there" options.
OR
Maybe...
If you were to decide to enable HP+
Then...
With HP+ service enabled, somewhere / some place , in some way you could use the OCR software that is apparently somewhere / some place in this mess.
OR
Go out and find, obtain, purchase OCR software and be done with all of it.
Be Aware - Enabling HP+ is a "big deal"
Assuming it is available on your new printer, READ everything on the website BEFORE engaging the service!!
HP+ does give supported printers access to Print Anywhere -- nice. Similar to the old ePrint tech.
