Or little computing tricks and hacks
We had the set up of the house network all done, everybody connected and working happily until we had to change the internet provider as we we had a mobile LTE (fast, mobile, of course, and practical). BUT, expensive if using more than 10 or 20 G per month. And we were. So we had to revert to the old fixed cable connection and have 130 G per month. So obviously, all of the various set ups had to be reworked.
The one I had some «trouble» was the scanner. The printer was fine, I just had to created a new printer and the new address was detected and that was all. But for the scanner to be detected by the scanning software (Simple Scan and Xsane Image Scanning) was a bit more difficult. Mind you: the scanner IS the printer.
For some reason, HPLIP (HP Linux Imaging and Printing) manager could not communicate to the device, despite all attempts of telling it that it had a new IP address. So I tried to do what one does when in doubt,,, Reboot. That is, try to reset or uninstall HPLIP to reinstall with the new parameters.
Given that I had not use Synaptic or Ubuntu Software Centre, I went to the manual option and followed the instructions here:
And presto. HPLIP was uninstalled. But we wanted it back. So I downloaded it again by following the instructions from: http://hplipopensource.com/hplip-web/index.html
In that page you can choose the specific parameter of your system to download the appropriate package and then you are guided with step by step instructions.
After that, I still had to work with the scanner. In a previous post, I had not voiced a preference between the scanning software packages. Now I have one. Simple Scan allows me to do what I need without fuss while Xsane creates a pdf file which creates some output errors for evince. Xsane took a lot longer to reset the scan parameters, and kept giving an error of not finding the device.
Simple Scan is, well, simple to use, without sacrificing functionality.
