Hi Peter,
Here is another approach for OS X that might give you info that's easier
to use. Or not.
put shell("system_profiler SPPrintersDataType") into tDescriptions
In my world it returns this:
--- start of data ---
Printers:
Canon iP1700:
Status: Idle
Print Server: Local
Driver Version: 5.8.3
Default: No
URI: usb://Canon/iP1700?serial=705357
PPD: Canon iP1700
PPD File Version: 1.0
PostScript Version: (3011.104) 0
HP Color LaserJet 2600n:
Status: Idle
Print Server: Local
Driver Version: 1.3.0501
Default: Yes
URI:
mdns://HP%20Color%20LaserJet%202600n._pdl-datastream._tcp.local./?bidi
PPD: HP Color LaserJet 2600n
PPD File Version: 1.0
PostScript Version: (3011.104) 0
Officejet Pro 8500 A909g [7134F4]:
Status: Idle
Print Server: Local
Driver Version: 1.2
Default: No
URI:
mdns://Officejet%20Pro%208500%20A909g%20%5B7134F4%5D._pdl-datastream._tcp.local./?bidi
PPD: HP Officejet Pro 8500 A909g Series
PPD File Version: 1.2
PostScript Version: (3011.104) 0
--- end of data ---
I see the URI line in each description tells if it is USB or not. BUT it
doesn't tell you the status of the printers; I got the same descriptions
when my USB printer was turned on/turned off/unplugged.
If I learn more I'll post it.

It returns "idle" in all cases? Are you saying that it doesn't
distinguish if the printer is on/connected vs off/disconnected?
How would I get the contents of the various printer properties from
this script into rev variables to test this out? Do I use an 'on
appleEvent' handler -- if so, how? Sorry for the naive questions, but
I haven't used applescript much.

Peter,
I was a little too fast with my reply, I am afraid
this gives me all the information of the current printer
unfortunately it
does return idle even if the current printer is off.
tell application "Printer Setup Utility"
set Current_Printer to name of current printer --> set a variable
for the
name of your current/default printer
set tKind to kind of current printer
set tproperties to properties of current printer
set tJob to job of current printer
end tell
Since you are looking for an active/connected printer this is
probably not
working.

this applescript tells me the currently selected printer on MacOSX
10.5.8

I have a stack system that is being used on laptops (at this point Mac
OSX only). One of my beta testers uses it in three different
locations. Among many other things, the stack prints out notes and
various other text files from within Rev (running in IDE on RevMedia
4.0 -- eventually I'll get to porting it as a standalone). As it
stands now, the user needs to select the currently available printer
using the system preferences. I need a way to discover if the printer
designated as active in the system preferences is actually the one
that is plugged into the USB port. I have a way for the user to change
the printer from within the stack, but I'd like to avoid the situation
where he tries to print something and gets the bobbing printer driver
icon in the dock telling him that that printer is unavailable (because
he's at a different site and forgot to change his printer
designation).
The ideal solution would be to be able to detect the currently
connected printer and send any print job automatically to that
printer, but I'd settle for just being able to post an alert when
trying to print to notify him that he is about to use an unavailable
printer. How do I detect what printer is connected? Or at least,
detect if a designated printer is connected or not?
