There is only that one entry in the ioreg output that contains
"IOUSBCompositeDevice" and that entry disappears if I unplug that
printer, so it's undoubtedly the listing for my laserjet. But there is
nothing in the ioreg listing that identifies the printer more
specifically, and thus there is no way of linking that entry to the
listing in my available printers just by looking at the names. (Not to
mention that the user can rename any printer in the system prefs
printer list to whatever s/he likes.)
I think I have found a solution that involves storing the printername
as the value of a customprop with key = the ioreg name -- do this the
first time the printer is encountered then use the customprop to set
the printername automatically after that. I'm testing it over the next
few days -- seems to be working so far -- and I will post the working
script (I hope) in a little while.

Hi Peter,
If you filter out all lines from "ioreg" output except ones that
contain "IOUSBCompositeDevice", do you see the printer name in any
line? If so, maybe available printer names could be matched to the
device names in "IOUSBDevice" and "IOUSBCompositeDevice" records.

This worked for me on my home printer, and I had high hopes for it,
but if fails this morning here at work. The problem seems to be
that with some printers the listing from the ioreg call has little
relation to the name of the printer. For instance, my Brother
laserjet MFC 8220 (combo printer fax copier) has an ioreg listing of:
+-o iousbcompositedev...@fd100000 <class IOUSBDevice, registered,
matched, active, busy 0, retain 12>
and there is no way of telling that this is a Brother 8220 or
relating it to the availablePrinters, not on the face of it, anyway.
I'm working on a solution that will involve storing the ioreg name
of a given printer as a customprop "ioregListing[printerName]" More
to come. I'm determined to make this work as invisibly as possible.
It has long been a irritation for me that the system doesn't
automatically just send print jobs to the available printer.
There's no reason on earth why you should have to change printers
manually (after the first time you use one, of course). The system
knows what's plugged in, for goodness sake. [grrrr...]

Everyone is doing it, so... here is what I came up with. Watch
line wraps please. Hopefully the comments explain what the code is
doing.
on mouseUp
answer UsbPrinterList()
end mouseUp
function UsbPrinterList
-- set item delimiter
set the itemDelimiter to tab
-- make a list of all active USB I/O devices
put shell("ioreg") into tActiveDeviceList
filter tActiveDeviceList with "*IOUSBDevice*" -- remove all but
USB devices from list
replace "@" with tab in tActiveDeviceList -- isolate device name
replace "+-o" with tab in tActiveDeviceList -- device name is item
2 of each line
-- get all known printer names, whether active or not
put the availablePrinters into tPrinterNames
-- identify active USB printers in the USB device list
put empty into tUsbPrinters
repeat for each line tDeviceLine in tActiveDeviceList
put word 1 to -1 of item 2 of tDeviceLine into tDeviceName --
could be partial device name
get tPrinterNames
filter it with ("*" & tDeviceName & "*")
if it = empty then next repeat -- device is not a printer
-- USB device is a printer, so get full name
repeat for each line tFoundPrinter in it
put tFoundPrinter & cr after tUsbPrinters
end repeat
end repeat
delete last char of tUsbPrinters -- trailing CR
return tUsbPrinters
end UsbPrinterList
Thanks -

Hi,
In English work, but in Spanish and others languages don't.
The result of the shell command is:
destino por omision del sistema: HP_Photosmart_C4200_series
So we must check for the ":" and get the printer name.
set itemdel to ":"
put item 2 of shell("lpstat -d") into tDefaultPrinter
function getDefaultPrinter
put word 4 of shell("lpstat -d") into tDefaultPrinter
-- shell returns: system default destination: HP_DESKJET_845C
replace "_" with space in tDefaultPrinter
return tDefaultPrinter
end getDefaultPrinter
The getActivePrinter get all the USB devices. In my case, my
LaCie disk, the
iPhone, the DataTraveler and the HP printer.. How to filter
between them?
Salut,
Josep
