Get a list of installed printers?

  1. 3 weeks ago

    I've been looking at how to manage printing in XoJo.

    I don't have much experience yet.

    It looks like most people use the printer dialog and then save a printer "connection string" for later connections.

    I'm going to use a zebra printer for my app. In the past, with .net you can print directly to them by sending ZPL/EPL commands as a string to the USB device.

    I want to have a printer settings window where the user picks the zebra printer from a list of printers, for future use. I want to by pass the printer dialog boxes completely because the app will print labels on specific events (so I don't want to have to stop, pick a printer, and click "print").

    I've looked at the SpecialFolders. I'm on a Mac and this is the output from /System/Library/Printers/Libraries

    drwxr-xr-x  3 root  wheel      96 17 Aug 19:47 USBGenericPrintingClass.plugin
    drwxr-xr-x  3 root  wheel      96 17 Aug 19:47 USBGenericTOPrintingClass.plugin
    -rwxr-xr-x  1 root  wheel   34464 30 Nov 01:33 commandInk
    -rwxr-xr-x  1 root  wheel  136048 30 Nov 01:34 ipp2ppd
    -rwxr-xr-x  1 root  wheel  102496 30 Nov 01:34 libConverter.dylib
    -rwxr-xr-x  1 root  wheel  161392 30 Nov 01:33 makequeuesagent
    -rwxr-xr-x  1 root  wheel   30176 30 Nov 01:33 snmpInk

    ( none of these entries are my printer.. )

    So I don't think SpecialFolders is the right way to go here. I've not seen a Printer class that allows you to enumerate the installed printers.. Is there something?

    be aware that the proposed method I give here will not work to publish on the mac app store
    as it calls to the system shell.

  3. That's perfect @Jean-YvesPochez - just what I needed.

    I'm not planning on using the App Store at the moment but thanks very much for pointing that out.
