manipulate this as needed

substrings after
"="

of
(selects
"portName from win32_printer where network=‘true’"

of
wmi
as
string
as
lowercase)

try changing network=‘true’ to network=‘false’

see if that will solve your use case.

Here is the w32_printer class from MS. You can look at the properties to find the filtering logic you need.

From a machine that has a printer connected in the manner you want to detect, try the following two phrases using the QnA or Fixlet Debugger tools.

selects “* from win32_printer” of wmi as string as lowercase

and

names of keys whose (exists name of it as version) of key “HKLM\SYSTEM\CurrentControlSet\Enum\USBPRINT” of registry

The first will give you a listing of the available WMI properties for each of the installer printers. Look for something to differentiate the printers you are interested in. It might be that the PortName is what you are interested in. I assume you are looking for devices with USB or Parallel printer connections (if anyone still uses these!!). I don’t have a directly connected printer, mine are all TCPIP connected so the PortName is the DNS name used to connect to the printer.

The second phrase should give you a list of all USB Printers that have been connected to the computer. You may have to include additional logic to determine if the printer is currently connected or simply one that has been connected at some point in the past and the USB driver loaded.
