Hello All, This has a tie in to networking, but start with CUPS. I have a HP LJ 4+, and it works well, and I have done a lot of printing to it from a system with a printer port. Now I am using an Acer TravelMate without a printer port. I have a USB to parallel port adapter, and it has worked, once. Now I just get one blank page, so there is communication, of sorts. I do not know whether there are problems with the adapter, or with the CUPS setup. At the moment, I do not know where to start looking, and quite what the configuration should be like. It is an out of date install of Debian 7, with issues about quotas and the like meaning I am not upgrading quite yet, but I am keeping it up to date as best I can, that does fit within the quota. I do have other printers, a Canon LPB5050N that uses a proprietary filter and setup with CUPS that also needs sorting, whether networked or USB. There are also a couple of Brother colour lasers that I can pull out and try with, but again, I need to sort out CUPS. There are "issues" about setting the printers up networked, I want to use wired ethernet, not wi-fi, but Network manager sets the wired ethernet as the default route, when it has to be the wi-fi. I need the wi-fi as the default connection as that is how I connect to the Telstra Netgear AirCard, and not yet conversant with connecting manually from the command line. I do have a network card in the HP LJ 4+, the Canon LPB 5050N also has an ethernet port, and the Brother printers will do wired ethernet, but still the need to do the default route through the wireless modem. I will be looking to get a cradle for the modem, and that can provide a wired ethernet port, but will still want to not connect the printers in a way that exposes them to the Internet. If you know of problems or issues with CUPS 1.5.3, or other comments and suggestions, please let me know. Regards, Mark Trickett
