PrinterDlg changes defaultprinter on Linux [message #47577] Tue, 31 January 2017 16:55 Go to next message

I am looking at this code in PrinterJob.cpp (CtrlLib)
void PrinterDlg::SyncPrinterOptions()
{
	Vector<String> l = Split(System("lpoptions -d " + String(~printer) + " -l"), '\n');
	paper.Disable();
	paper.Clear();
	slot.Disable();
	slot.Clear();
	for(int i = 0; i < l.GetCount(); i++) {
		FillOpt(l[i], "pagesize", paper, true);
		FillOpt(l[i], "inputslot", slot, false);
	}
}

and I think that "lpoptions -d " should be "lpoptions -p " to avoid changing the default printer for all programs of that user, but then it stops working.

Documenation seems confusing, but it looks like -p actually does not allow -l after it...

Ah, sorry it seems I didn't quote the original code.
It is
Vector<String> l = Split(System("lpoptions -l -d " + String(~printer)), '\n');

that seems to first list the options and then change the defaultprinter.
Not correct I think as you get the options of the previous printer.
If I change it like I wrote in the first message then it works correctly but still changes the default printer when used.
the -p works ok on the commandline but then the dialog doesn't return the correct printer as it seems to rely on changing the default printer.
