Scanner 'Copy' functions.

Hi everyone, this is probably a very stupid question, but after a few hours
of searching, I cannot find an answer.

Here's the situation: on the back of several HP Scanners, there are a pair
of parallel ports. One to the computer, and one to the printer. If I read
the manual properly, you are expected to connect the scanner via USB, and
the parallel connections are just for the printer?
(this is not a problem for me, I'd just like it all clarified before I put
down dollars for hardware)

But what I'm really curious about is according to the manual if you press
the 'Copy' button, it prints via the computer to the default printer.

What I want to know is can it print the copies directly to the printer, by
the parallel connection.

IE. in the situation where:
the printer is connected via parallel cable to the scanner.
the scanner is connected via USB cable to the computer.
the computer HAS NO PRINTER INSTALLED.

can the scanner 'copy' items to the printer?

Thank you!

I don't know exactly what model you are talking about, but with parallel
port scanners, the parallel port is a "pass through".
The scanner would have to be connected via parallel port first, then the
printer to the pass through parallel port.

Obviously, the printer can't work unless it is actually connected to
parallel port of computer, either directly or using passthrough.

Of course, the printer can be connected to computer, scanner to USB, and
the scanner can still "copy" to the printer in this manner.

Nuts.
I was hoping I could remove the computer from the equation.

My plan was to buy a used workgroup b&w laserprinter, as I do some
voluminous printing, and I'm tired of the run of the mill printers crapping
out on me, and automatic duplexing is something I've wanted for a long time.
I'm leaning heavily towards the HP Laserjet 4050dn. But I want to be able to
copy too. So I need a scanner.

I don't know how much I trust the 'multifunction'
printer/copier/scanner/fax/kitchen-sink devices. I've found in the past that
the more functions a device seeks to incorporate the lower the overall
quality.

It also occured to me that I have no idea if 'voluminous' is a word. Anyway.

I was hoping that the inclusion of a parallel port on the scanner indicated
that it could send raw data to the printer. The only system with Windows in
my house is this laptop. Everything else is linux, and I strongly suspect
that the various function buttons on the front of the printer only work with
proprietary software, which requires windows.

If I could set this up to do one button copy on my gentoo server, life would
be sweet....

At least on my epson perfection 2400, and probably any other epson
scanner, the function buttons on the scanner is registered in vuescan and
can be programmed to make a copy. However, vuescan is a full fledged
scanner program, and runs in X, i don't think there is an daemon mode.

I was only talking about parallel port scanners that are within my scope
of experience. Perhaps there ARE scanners that will do copies straight to
printer. Certainly a lot of printers that will take images directly for
media cards, for example, no puter required. Don't take my word as gospel
without doing more research.

On further thought, though...printer driver would have to be embedded in
the scanner, eh? Can see maybe Epson or someone being able to do that, if
printing to Epson printer, and like that. But to print to most any
printer, a scanner would have to have a programmable interface that would
accept different manufacturers' printer drivers. And of course, that
interface is, well, a computer :-)
