I attached an old Brother HL-2040 printer to my DS213j and the Synology finds it, but when I go to print to usbprinter it sometimes works, but more often just sits there with no error msg or results. However, in those cases, if I print to the HL-2040 printer that also appears in my list of available printers, it does print. Sometimes I even get a double copy of the printout, as though the usbprinter had spooled the file, but didn't want to start until a print to the HL-2040 printer selection triggered it.
Any ideas what I should check? Thanks.
