Leandro's questions

I am trying to use the scanner of my printer Laserjet M1212nf MFP with both xsane and Simple scan. For the first I got the following error:

Failed open device
'hpaio:usb/HP_LaserJet_Professional_M1212nf_MFP?serial=000000000ST10HPQPR1a':
Error during device I/O.

If I try Simple Scan, from both graphical interface and terminal the returned error is :

unable to connect to scanner. 

The hplip plugin is intalled and the hp-scan -g gives the following information:

I reinstalled hplip several times following instructions of Official Hplip home page and nothing is working. Any suggestion is appreciated.

I am running Ubuntu 18.04 and some time ago I have installed the HPLIP software from the official web site because the one in the repository was not working properly. Afterwards I had no problem, until today. Now if I try to perform a regular upgrade I am getting the following error:

I am trying to install a multifunctional printer Laserjet M1212nf MFP on Ubuntu 12.04. I downloaded and install the hplip indicated by the official web site. At the end of the installation I chose reboot the whole system and next I call hp-setup in the terminal (as normal user and then as root). After select in the dialog box my printer I got the following error:

Searching... (bus=usb, search=(None), desc=0)<br>
/Traceback (most recent call last):<br>
  File "/usr/share/hplip/ui4/setupdialog.py", line 1255, in NextButton_clicked<br>

    self.fax_name_company = unicode(d.getStationName())<br>
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 20: ordinal not in range(128)

I think at this stage the plugin should be downloaded, but it is not working. Any suggestion on how to solve this problem ?

Edition:

After running hp-toolbox I got the following error message :

I am Ubuntu 10.10 (64 bits) user and I would like know how to make Nautilus display a customized svg icon for all my latex files.

Searching for this information, I discovered that the program Assogiate is capable of to replace the default icon assigned to the latex files by a customized svg icon. For the other hand it seems that there is a bug related to Assogiate and Nautilus.

1-Could you point me any workaround to solve the problem between Assogiate and Nautilus ?
2-Is there another program that could be use to this end ?

Thanks.

PS: After change the latex file icons using Assogiate it is possible to see the new icon in Thunar.

I decided to move from Lucid to Maverick in my office computer and I wanted to make a backup of some files on DVD.

For this i tried Brasero and them k3b, both programs are not working with if the folder or files inside them have at least one space character. The most part of my files have space in its name so it would be a pain to rename all of them.

01- If I understood correctly, this problem is related to a kernel issues and not to these specific softwares am I right ?

02- I ask the archive manager to create a rar file broking the back up in files of 600Mb. In this way I was able to burn them but they are not accessible from archive manager. Is this related to the size I chose to broke them ?

03- Is there any other workaround or fix that I could use to make this backup on dvd's ?

Thanks.

I have a wireless mouse device and I would like to speed-up the scrolling. I found a hint that tell us to install gpointing-device-settings.

Unfortunatelly this program is not working in Lucid.Trying to running it one get a segmentation fault error, so I went here to ask how to manually speed up scroll ?

gsynaptics is also not working for me.

I would like to install Evince 2.32 in Lucid (10.04)

1. Is there any safe way to do it ?
2. Download the source and start install all the required dependences is this approach dangerous for the stability of my system ?

I googled for a solution of this problem and the only suggestion I found it was to add the ppa:irie/evince. I guess this is a not so safe am I right ? If so it is expected to work with Lucid ?
