问题
I have two users now that tell me that the standard TPrinterSetupDialog in our Delphi 2007 application does not list all installed printers.
One user just installed a Canon D1300, it is selected as the default printer in control panel but does not even show in the list in the PrinterSetupDialog.
Another user reported the same problem with a Xerox Phaser 8560, it was also the default printer in control panel.
Is there any know reason that this could happen.
