That was supposed to read 75, 150, *300* and 600dpi

Forget about theory, in actual practice, many parallel ports can only
transfer as few as about 5,000 bytes per second. That is 3 MINUTES per
megabyte, roughly. At 600 dpi, you should be sending about 4 megabytes,
so up to 12 minutes might be necessary (there is no reason why you
should be sending 25 megabytes per page).

Suggestion: Get a USB printer, or get a used Laserjet 4 or 5 and the
"Jet Direct" (Ethernet) card and use Ethernet. Anything instead of a
parallel port.

Is that 5 min of spooling?

Do you have the printer set to print now instead of wait until spooled? (I
forget the actual language)

Sounds like a software problem with whatever you're using to scan and
print. Try scanning to a bunch of files and then printing those with
various apps.
You can reduce the resolution of the images using, e.g. Irfanview,
which can do a batch of files at once. It's also pretty flexible for
printing.

Also you don't say what driver you're using. If it's mostly bitmaps,
probably the PCL driver rather than the PS will be faster and require
less data to be transmitted.

Also the 4MP should come standard with an Ethernet port (on a
Jetdirect card, it can be removed though). If you have that try it
connected to your router as a network printer instead of the parallel
port.

One other factor:

Have you put the amount of memory in the printer device settings in
Windows? Windows has no way to know otherwise that you have 18MB of
RAM and will use as default the minimum shipped (2MB + 4MB on the PS
SIMM). Which means it will send data to the printer in dribs and drabs
so as not to overflow the small amount of memory it assumes.
