postscript does work.

The only problem is that some pages demands a lot of memory and the 
printer bails out; and that printer memory is (was?) more expensive than 
computer memory (can't it use a local disk or flash memory, and swap to it)?

Yes, the printer needs a processor. On the other hand, the computer 
needs less work.

The thing is, Linux did not need to create a printing engine. 
Application devs were told to just output postscript and send it to the 
printer. Problem solved, instantly.

Windows does (did?) it differently (unless it changed since I looked at 
it long ago). The application creates a GDI, one for the display, 
another for the printer, and generates on it the output in the same 
manner for one as the other.

<https://en.wikipedia.org/wiki/Graphics_Device_Interface>

GDI printers

A GDI printer or Winprinter (analogous to a Winmodem) is a printer 
designed to accept output from a host computer running Windows. The host 
computer does all print processing: GDI renders a page as a bitmap, 
which the printer driver receives, processes, and sends to the 
associated printer.[10][11] The combination of GDI and the driver is 
bidirectional; they receive information from the printer such as whether 
it is ready to print or is out of paper.

Printers that do not rely on GDI require hardware, firmware, and memory 
for page rendering while a GDI printer uses the host computer for this. 
However, a printer with its own control language can accept input from 
any device with a suitable driver, while a GDI printer requires a PC 
running Windows. GDI printers can be made available to computers on a 
network if they are connected as shared printers on a computer which is 
on and running Windows. Some "generic" GDI drivers such as pnm2ppa have 
been written; they aim to make GDI printers compatible with non-Windows 
operating systems such as FreeBSD, but they cannot support all printers.[10]

In order to allow simpler creation of drivers for Winprinters, the 
Microsoft Universal Printer Driver was created. This allows printer 
vendors to write Generic Printer Description (GPD) "minidrivers", which 
describe the printer's capabilities and command set in plaintext, rather 
than having to do kernel mode driver development.

Microsoft has moved away from this printing model with Open XML Paper 
Specification.

I think, not sure, no personal experience, is that you can not run 
applications remotely as with X over an ssh connection.
