It's working well so far. Even jobs which I can see have a non-existent port number in the log, are no longer spooling to a file. AFAICS, it's good to go. If I encounter any glitches, I'll report them right away.
Upon closer inspection, there is still a glitch. While saved jobs will print (not get spooled to a file), there is still a lack of communication between QU and the printer driver. Saved settings don't appear to be sent to the driver. If I recall a print job with all settings, which is my normal procedure, and then bring up the "Printer Setup" dialog box and go into "Properties...", any changes I make at that time in the driver settings appear to be discarded when I exit back to the "Printer Setup" dialog box.
However, if I first choose a
different printer, then re-choose the desired printer, then any changes I make in the printer driver through "Properties..." are kept.
Cheers!
