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.showAddPrinterPage()<br>
  File "/usr/share/hplip/ui4/setupdialog.py", line 690, in showAddPrinterPage<br>
    self.readwriteFaxInformation()<br>
  File "/usr/share/hplip/ui4/setupdialog.py", line 1079, in readwriteFaxInformation<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 :

Unable to communicate with device (code=12): hp:/usb /HP_LaserJet_Professional_M1212nf_MFP?serial=000000000ST10HPQSI1c

I think the problem is with return content_type, content.encode('utf-8'). The solution is the replace the characters to modify the program line:

return content_type, content.encode('utf-8') as
return content_type, content.decode('utf-8', 'replace').encode('utf-8')

This does nothing just replaces the character. refer to this

Maybe this can help you out

thanks for reply ashutosh, Could you give me the file name where I should write this modification ? –  Leandro Apr 30 '12 at 21:35
    
It's just there in the error output. it's /usr/share/hplip/ui4/setupdialog.py. Try making change there –  ashutosh Apr 30 '12 at 21:38
    
I did not find any entry in this file with return content_type or content.encode('utf-8'). Is there any other file that I should look at ? –  Leandro Apr 30 '12 at 21:53
    
Maybe you can see if /usr/share/usb.id is not missing rootfs. If that is the problem, trying adding the file to rootfs –  ashutosh Apr 30 '12 at 22:07
    
This can be another problem, I don't have this file usb.id in this directory. Perhaps I should fill a bug report on launchpad. Thanks anyway! –  Leandro Apr 30 '12 at 22:20
