I have a hp laserjet iii and wonder what the expanded ram is good for, what
is the advantage of having more ram?

Probably postscript. More ram means bigger images etc can be printed with half
tones.

Also applies when priting complex documents in say desktop publishing. On
my 4L with onlt 1MB ram, sometimes I get only part of a document printed
because the printer runs out of memory.

Try printing a page full of graphics and you'll find out. Unlike inkjets and
some cheaper laserjets this hp has to load the full page into memory prior
to printing it.

Thanks for this and the previous replies by others.
So if I understand correctly the memory is used for 2 things, 1 to load
software fonts into and 2 to store the document before printing and
therefore you must have enough memory to hold the entire page in the printer
memory. I have 5Mb of printer memory which is the maximum for this printer I
think.
I just tried printing a 8.4Mb tiff photo and it printed no problem, this
exceeded the 5Mb memory I have but I noticed that it was printed very
quickly as if it was not loaded into the printer memory first, I have
noticed some documents taking quite a while to load into the printer before
printing so I can only assume that something's load to printer memory and
others just go straight go through without been loaded into printer memory
first, I would like to know why something's do this and some don't.
Also in this day and age is there any need to download fonts to the printer
memory, I am wondering if this is what causes the slow download to printer
on some documents as I just explained above i.e. are fonts automatically
downloaded to the printer memory before printing a document so that if I
print a webpage for example the font needs to download first before the page
is printed and this is what causes the delay. Or am I way off base? If not
then I guess the purpose of manually downloading fonts or having a font
cartridge is so that pages using these fonts are printed quicker.

Woops I have never top posted before except when a thread is already in top
posting mode, it's never happened in all these years, don't know why it
happened now, maybe my brain is getting confused by the top posting I have
to do in threads that are already in top posting mode, something that was
less common in earlier years and therefore my brain didn't get confused.
Anyhow I thought I should mention that I am not using page protection which
if I understand correctly forces the document to be loaded to printer memory
first although I thought this happened anyway so am a bit confused.

I'm not exactly certain, but I don't think it's the size of the input data
that matters, rather the size of the print job when converted to it's
printer language ie PCL, PS etc.

Whether or not a 8.4MB tiff takes up less than 5MB when converted I have
no idea. But if it was a colour photo it could be losing a lot of colour
depth info going to a black and white printer. Also from memory tiffs
either have no compression, or a method that isn't very aggressive - I
have no idea what compression PCL uses, but that could be a factor.

Tiffs use some form of LZW compression, but I think there are different
compression options available when creating them.

I thought that they were images with pagination, ie, suitable for faxes
etc that have multiple pages.

Im not sure that I have used the correct term, but thats the format that
I have seen faxes in on a number of different packages.

Someone here at work says that the original tiff used LZW, but it is
usually a container format that can hold other file formats ie, jpegs etc.

Thanks, yes it is a colour photo and when the colour info is taken out could
well be smaller than 5Mb, I didn't think of that, good point. This tiff file
has no compression, it was originally a jpeg file which I converted to tiff
with no compression.
From what I understand now though it would not matter if the file was bigger
than 5 Mb as without page protection on, the printer will just print the
file on the fly as it comes from the computer without trying to store the
complete file in it's memory.
