TCL: using twapi package to get printer details

I am using twapi 4.1 version to get the details of a printer ("myprinter). Below command works and gives me expected results.

set printerData [twapi::recordarray getlist [twapi::enumerate_printers] -filter {{-name eq myprinter -nocase}}]

However, I cannot pass the printer name as an argument to -filter option.

Below code doesn't work:

set printerName "myprinter"
set printerData [twapi::recordarray getlist [twapi::enumerate_printers] -filter {{-name eq $printerName -nocase}}]

I tried different formats (using subst command and all) but nothing worked.

Any idea how can I pass the printer name as an argument? Thanks in advance for your help.

The problem is that tcl doesn't evaluate the string inside curly braces, so you should change your code using the list command instead:

set printerName "myprinter"
set printerData [twapi::recordarray getlist \
                 [twapi::enumerate_printers] \
                  -filter [list [list -name eq $printerName -nocase ] ]\
                 ]
