Are you sure?
I've had laser printers with a whopping 4MB of RAM that can print a
600dpi A4 page. Their ability to process a job without choking seemed to
depend mostly on the contents of the job and the app that produced it.
For example, huge TIFF images from QuarkXPress tended to stop it in its
tracks, but Acrobat Reader's progressive rendering option could send the
same job to the printer with the same options with no problems.
It seems like printers can progressively render the pages so long as
some conditions are satisfied. I've never understood quite _how_ they
can do that, but I just don't see any other way for a 4MB printer to
handle a job like that.
Also, if you're not using PostScript as the final printer language,
memory is potentially much less of an issue. IIRC PCL is quite RAM
efficient and is oriented toward progressive rendering; most other
printer languages are lower-level control languages that send the
printer raster data directly. That said, for reliability it's hard to go
past a printer with a genuine Adobe PostScript RIP... but be VERY leery
of "PostScript emulation". Very.
