"Usable" is a relative term. You can always do something like this:
oServer = CreateUnoService("com.sun.star.awt.PrinterServer")
oCore = CreateUnoService("com.sun.star.reflection.CoreReflection")
oClass = oCore.forName("com.sun.star.awt.XPrinterServer")
oMethod = oClass.getMethod("getPrinterNames")
aNames = oMethod.invoke(oServer, Array())

Ah, I see. This does work.
Can you explain why the intermediate step using Core Reflection is
necessary, please?
>From those old times there is another macro that must have been working,
and it doesn't (work or use CoreReflection):
function PrinterNameListNew
ps = CreateUnoService("com.sun.star.awt.PrinterServer")
dbgM(ps)

dim xps as object
xps = ps.QueryInterface("com.sun.star.awt.XPrinterServer")
if NOT IsNull(xps) then
dbgM(xps)
else
msgbox "NULL"
endif
PrinterNameListNew = ps.getPrinterNames()
end function
TIA,

Wow, thanks. Thanks to Ariel, I have a few links, one of which
brings me here:
http://openoffice.org/projects/api/lists/dev/archive/2008-08/message/66
Which I assume explains why we need to jump through the hoops mentioned
above. I am amazed Never occurred to me that this could be done.
Marc, in answer to your question of why, I assume that it is because the
type detection stuff is not in place so Basic cannot see the required
interface. (or something like that Did not give that comment much
thought since my three year old is dragging me off my computer chair).
Thanks!

So this means the problem with this absolutely unusable (despite the
CoreReflection hoops) service is known for more than 2.5 years already,
and nobody of us developers ever cared? Shame on us!
Known as http://openoffice.org/bugzilla/show_bug.cgi?id=117765 now,
fixed in CWS fs35a.

As Andrew wrote: The usual logic, where Introspection finds the methods
from all supported interfaces, requires XTypeProvider.
From those old times there is another macro that must have been working,
and it doesn't (work or use CoreReflection):
function PrinterNameListNew
ps = CreateUnoService("com.sun.star.awt.PrinterServer")
dbgM(ps)
dbgP(ps)
dim xps as object
xps = ps.QueryInterface("com.sun.star.awt.XPrinterServer")
if NOT IsNull(xps) then
dbgM(xps)
else
msgbox "NULL"
endif
PrinterNameListNew = ps.getPrinterNames()
end function
In fact, this will work in 3.4, where the "Type" parameter for
queryInterface can be given as a string (issue 116184).

Hi,
Issue 117765 is good news.
But this service com.sun.star.awt.PrinterServer is not documented in the IDL !
Only its interface. I hate using undocumented API. Can it be also corrected ?

Excellent!
I documented, so it will be in my latest OOME document when I push it
out Not nearly sufficient, however.
