You're welcome!

And I really mean what I said - if you (Xavier or anyone else who
uses it) - let me know how you get on with it. You know, like,
talk to me. E-mail me. Start or join in with a thread on a news
group.

I'm not looking for thanks (although they are always welcome!),
but I /am/ looking for feedback. Does it work? Does it work well?
Was it easy to install? Was the documentation good enough? Does
it provide all the features you want, or is there something else
you'd like to see?

It's somewhat disheartening to release an app and hear /nothing/
from anybody.

Don't be too disheartened. If noone says anything it could well mean
that they just didn't have any problems and find it perfect. :-)

I'm afraid I have no use for it but thanks for releasing it. Another

When I have Post Script 3 selected, and a linked PC, and JDServer on
the icon bar, every now and again the printer manager complains that
it doesn't know what to do with the file to be printed i.e. it thinks
it is a file that cannot be dropped onto a printer driver.

I will try and replicate exactly the situation this evening.

Any suggestions?

Sorry, I've not really made myself clear!

I normally have print output set to Postscript 3 driver to produce a
PDF for saving and sending or putting on a website.

Making my laserjet 5 active, the PC on a wireless network prints
faultlessly through the Iyonix which has the physical connection to
the printer.

When the PS3 driver is active ... example ...

I loaded Architech 3D modeller in answering a query on the newsgroups
... Within a minute up popped an error box:

Query from print manager
Don't know how to print Printout files;
print !Architech as plain or fancy text?

This error box normally occurs when you drop an unknown application's
file onto the printer to be printed.

I haven't sent anything to be printed.

True, that's always possible!

I have to say, that for the average RISC OS user who doesn't do complex
programming, the single most important thing that you can do to encourage
software development, other than spending money where applicable, is to send
feedback (positive or constructive criticism) to the developers. Don't just
rely on developers reading the newsgroups or Archive On-Line or whatever, as
we are not all subscribed to all lists, and don't always keep up with them.

Knowing that someone is using the software, or is attempting to use it, is
the greatest spur to finding time to make improvements and new releases.

(And to avoid charges of hypocrisy, I should now fire off e-mails to various
developers to thank them for useful pieces of software myself.)

Just works on this Iyonix. Only needed loading!

Printing from Xandros 3 last free edition a doddle to set up once one
realises the printer definitions are already there and have read the manual!

Interestingly, remote printing now fully-multitasking with RISC OS
Gimp-Print driver for Epson Photo 700 despite Background Printing being
unticked on RISC OS driver!

Thanks, Dave!

I now anticipate being able to print out those Ryanair Boarding Passes
without having to piece together RISC OS screenshots in Draw!

I think this may partly be due to what I describe as "The Classic FM
Syndrome". They tell you the title of the piece and the composer and
it doesn't register at that moment; then the presenter rabbits on
about the work but never again says what it is. Only at the end of the
work (if you're still listening) can you pick up what it was.

That's the problem here, for me. I don't recall what the program is
for - and I long ago deleted that posting, assuming it didn't fit my
set-up. Trying to work out its purpose from all the replies is more
difficult than Sudoku.

Please will you repeat (for those who didn't concentrate properly)
what the program is and does?

But I accept your point about feedback - plus as well as minus.

My solution to this is to copy (in Pluto hold down shift to get
Copy instead of Move) any article of possible future interest,
eg comment or info about a new program, to a non-expiring box.
When the subject come up again or you have a bit of spare time
to investigate, the topic can very easily be picked up without
an extensive search.

Surely in this case, the time between Dave posting about JDServer and this
thread is so short that the messages won't have expired anyway? If they
have, your expiry time is probably set too short.

As such, finding what was in the original announcement should be a case of
asking Pluto to show the original post in the thread. I don't use Pluto,
but in M-Pro this is usually a simple case of going to the message ancestor
menu and selecting the first entry -- I'd guess that there's a parallel in
Pluto. I say "usually", as sometimes broken news clients damage the
References header: in this case, the process may need to be repeated to get
past each break in the chain.

I don't understand why anyone would expire csa.announce posts. They don't
get less relevant just because they're old(er).

It's one of the groups that I keep everything from, except that when
somebody announces version x+1 of something, I delete the announcement of
the prior version. That means I always have a folder full of the most
recent announcements. Typically there's around 300 posts in the folder.

Or, use Google to find the thread in their newsgroups archive, eg at

You just answered your own non-understanding. Those of us on RISC OS
using Pluto can easily call up posts from Google which are no longer held
locally though I understand that anyone using a crappy windoze newsreader
(or even Gemini!) may be unable easily to refer back to an earlier post
when a poster fails to quote context or wishes to delve into posting
history.

So let's see if I understand correctly:

1) You've set JDServer's "Filetype" menu to "PoScript"?

2) You load Architech on your PC;

3) Even though you don't print anything from Architech, or indeed
from any application on any computer on your network, a query box
from the print manager pops up asking whether to print Printout
files as plain or fancy text?

If the answers to (1) and (3) are both "Yes", this is a real
mystery, because JDServer sets the filetype of each spool file,
immediately after it has closed it (i.e. when the client computer
finishes its print job), to the type set in the "Filetype" menu.
If you've configured JDServer to "PoScript", it should set the
filetype to "PoScript". If the "SetType" command doesn't get
executed, the filetype will be "Data" - it doesn't default to
"Printout".

... well, if your Choices: system isn't working correctly, your
Filetype choice won't be saved, and/or won't be read back, so
the filetype will default to "Printout" every time JDServer is
started.

You don't have Choices: set to a RAMdisc, do you? Or to some
medium that can't be written and/or read?

Look at what filetype is shown on JDServer's Filetype menu
when you first boot it, and tell me the result.

Also, if it happens again, please send me the debug log. You
should find this in $.!Boot.Resources.!SysLog.Logs.JDServer.

A computer wanting to print a small Postscript file on startup
of an application doesn't surprise me too much; maybe it's
trying to configure the printer in some way: paper feeds,
duplexing, etc.

If you have more than one printer driver loaded on your RISC OS icon bar,
say one PostScript and one HP PCL would having the wrong one selected cause
a problem?

IIRC you can't drop a 'Printout' typed file onto a PostScript printer only a
PostScript typed file!
Which I guess is why you have the setting you mention above

You need RemotePrinterFS, by Stefan Bellon, which you can get from
http://www.sbellon.de/sw-modules.html

On the client machine (i.e. /not/ the one running JDServer), set
the printer to print to file, with a file name such as:

RemotePrinterFS#proto=JetDirect;host=Iyonix:

or:

RemotePrinterFS#proto=JetDirect;host=192.168.0.2:

according to whether the JDServer machine is in the client's Hosts
file (so you can refer to it by name, as in the first example), or
not (so you have to refer to it by IP address, as in the second
example). Clearly, replace "Iyonix" by your JDServer machine's
hostname if you're referring by name.

Bad terminology, I'm afraid.

At the top of the message window is a pop-up menu named 'Thread'. It
contains 'Show parent' which does what it suggests (goes to the message to
which the current one was replying), and submenus for Ancestors, Replies and
Sibligs. Ancestors /should/ take you back all the way to the first post in
the thread, but broken clients can damage the References list. Usually you
can repeatedly select the oldest ancestor in the list to step back past such
damage, however.

Unfortunately, the web-based printing system used by Ryanair seems, when
printed out on my Iyonix as server from a web page under Linux (Xandros3)
prints out at what I guess to be double size, so won't do for presentation
at the airport.

I have checked that the resolution of both printer drivers is similar.

I note from what I have read that each machine needs the same printer
driver - but doesn't the sending machine send a raw print file - and
consequently the local (to the printer) driver shouldn't really matter? It
should be that the raw file is matched (appropriate) to the printer - but
does it matter what setting the final driver has?

Or am I misunderstanding what is (or might be) going on?

Hoping for a better understanding.

Let's see if I can help with that.

Each machine needs its own printer driver.

JDServer passes the data on to the printer manager, which in turn
passes it to the printer. At no stage does any component on the
RISC OS machine interpret or change anything sent by the client
machine - they are all raw print files (filetype: Printout) or
PostScript files (filetype: PoScript) as set on JDServer's menu,
hopefully to match the printer's requirements. The functionality
is simpler than you think.

The configuration settings in the RISC OS Printer Manager are
only relevant to printouts performed wholly on the RISC OS
machine.

That was what I initially surmised.

So it's just like saving a 'printout' file on a 'Windows' machine,
transferring it to a RISC OS m/c, and printing it.

So why does not any printer driver file work under RISC OS? Or does it?

If the 'printout' file is sent directly to the printer by the printer-local
driver, having been formulated by the printer driver on the originating
machine, why does it matter (if it does?) what driver is present on the
RISC OS m/c?

And in what way does this differ from what happens with UniPrint (a
commercial product)?

It's the concept I'm really after, to understand what's going on.

Exactly. As simple as that.

The RISC OS printer driver is not involved. The RISC OS printer
manager is, simply to queue the files and transmit them to the
printer.

The answer is above.

UniPrint is a different concept.

It's simpler than you appear to be thinking. All it really does
is to move the connection point of the printer from one computer
to another.

It's pretty much the exact opposite. With JDServer, the 'hard work' of
turning the printed page into commands for the printer is done on the
originating machine. JDServer just blindly passes these on from the network
to the printer.

With UniPrint, it's the receiving end which knows how to drive the printer.
The sending end is the one that (not quite so blindly) passes the data out
across the network.
