A: Canon printer problem on Ubuntu 18.04

pdcfor any driver, there are at least 2 steps: 1) install the drivers and 2) register the printer with lpadmin (print spooler) this needs the CAPT driver; as you know, but there are three steps: please copy the commands below; paste into the terminal; hit the ENTER key to action .. 1) install the...

When I do the second step, I get this error message --- lpadmin: Unknown argument "–E"

sorry; Ubuntu likes the full path; please see above

I did whatever you told me but last part is not happening. I am not getting an offer to do a test print. Rather nothing is happening after third step. Also I got a message on top saying "Additional Printer Drivers Required".

Actually, the CAPT install may not prompt a test print offer; but if you go to LibreOffice; and try to print some text from there; do you see the LBP2900 listed as a possible printer? Can you print to it? (You may have two icons for the LBP2900; one may say LBP2900/LBP3050/LBP3100 or something .. ignore that one)

I tried to print from "Text Editor" and there I can see two printers. I used both of them, and no one is working.

what does lpinfo -v give in a terminal please: if you add the answer to your top question; then it is easy to see; thanks
 
Manoj
Manoj
Done! You can check the question now.
 
pdc
pdc
can you now do lsusb in a terminal and paste back what you get please; also if you open the dev/ folder; and turn on the LBP, can you see a folder appear called usb and inside what do you see please?
 
Manoj
Manoj
Posted information about lsusb. Now what do you mean by turn on the LBP? (sorry, new to linux)
When I open Dev folder, I can see USB folder, inside it I can see two files. One is "hiddev0" and other is "lp1".
 
pdc
pdc
please see answer in the answer section above:
 
Manoj
Manoj
sudo /usr/sbin/ccpdadmin -p LBP2900 -o /dev/usb/hiddev0 This didn't work.
Which icon you are asking me to delete from printers folder? Where the printers folder is located?
 
pdc

if you enter printers in the search area; and find it from there; I suggested that if an icon for the LBP 2900 didn't work, you delete it; please try the lp1 command and make sure you do the "ccpd start' command after that
 
Manoj
Manoj
When I use this - sudo /usr/sbin/ccpdadmin -p LBP2900 -o /dev/usb/lp1.................................I see this - LBP2900 can't find in CUPS Spooler Entry!!
 
pdc
pdc
I have added B to the 2900 to make it 2900B can you try the commands again with that; I can only assume the mouse is hiddev0 and the printer; if turned on and reading to go; is lp1
 
Manoj
Manoj
LBP2900B can't find in CUPS Spooler Entry!! Same problem.
 
pdc
pdc
I am running out of suggestions; this is CUPS localhost:631/admin from your web browser; paste this address or just click on it; look in FIND NEW PRINTERS: does CUPS find your 2900? It seems to show in lsusb but it didn't seem to me to show in lpinfo -v
 
Manoj
Manoj
When I click on FIND NEW PRINTERS, I see No printers found.

if you click on MANAGE PRINTERS, do you see the LBP listed there please? If there is, please delete any icons for the 2900; and re-run the 2 register commands and restart ccpd
 
Manoj
Manoj
Yes, there are two printers listed but when I tr to delete it, I see this message. Unauthorized Enter your username and password or the root username and password to access this page. If you are using Kerberos authentication, make sure you have a valid Kerberos ticket.
 
pdc
pdc
then find your PRINTERS folder; and do it from there
 
Manoj
Manoj
Ya, I did it. Same result.........can't find in CUPS Spooler Entry!!
 
pdc
pdc
I am out of ideas
 
Manoj
Manoj
