[SOLVED] system-config-printer non existant module cupshelp

[rafa_99]

Hi, I'm new to gentoo and I was now ready to setup my HP printer. Back when I was using artix linux I used to use system-config-printer gtk interface to set it up.

And thats exactly what I did in gentoo, managed to install cups(already active with rc-service cupsd start) and system-config-printer, and now when I type in the command:

Code: Select all

system-config-printer

I get this error:

Code: Select all

$ system-config-printer
Traceback (most recent call last):
  File "/usr/share/system-config-printer/system-config-printer.py", line 76, in <module>
    import cupshelpers
ModuleNotFoundError: No module named 'cupshelpers'

I've then tried to install system-config-printer with all of the USE flags enabled but still get the same error...
Also tried to install net-print/cups-pk-helper as a try of using it has a helper, but got no luck...

Can anyone give me some pointers/help/alternative regarding my problem?

Thanks in advance

PS: Tried looking for that python module, but no sucess

In your web browser, go to:

Code: Select all

https://localhost:631/

Added: I'd never heard of app-admin/system-config-printer

Hello,

I just spent a day trying to work out, why is my (a year ago installed USB printer) missing.

For anyone with USB printer not being listed under [ Find new printers ], make sure:

1. net-print/cups has 'usb' use flag set to OFF!
With the 'usb' flag enabled my Lexmark B2338dw disappears, though usb backend lists it fine (net-print/cups-2.3.3_p2-r3)

Code: Select all

$ /usr/libexec/cups/backends/usb
direct usb://Lexmark/B2300%20Series "Lexmark B2300 Series"  \
 "Lexmark B2300 Series" "MANUFACTURER:Lexmark;COMMAND \
SET:PCL 6 Emulation, PostScript Level 3 Emulation, PDF, URF, PWG, NPAP,  \
PJL;MODEL:Lexmark B2300 Series;CLS:PRINTER;DES:Lexmark  \
B2338dw;CID:LexmarkPrinterMonoA;COMMENT:ECP1.0, LV_043D, LP_029B, LF_00B3;" ""
// backslashes added to make it more readable...

but

Code: Select all

$ lpinfo -v
network beh
network ipp
network lpd
network http
network ipps
network https
file cups-brf:/

so no USB printer here... Weird logic, must say.

2. Make sure /var/spool/cups and underlying tmp dir have correct permissions.

Code: Select all

$ ls -ld /var/spool/cups /var/spool/cups/tmp
drwx--x--- 3 root lp 72 02-18 21:17 /var/spool/cups
drwxrwxrwt 2 root lp 88 02-18 21:17 /var/spool/cups/tmp

Without the permissions, I was able to click-through the [ Add Printer ] wizard, but in final the printer wasn't there...
I added the printer from CLI:

Code: Select all

$ lpadmin -i my_lexmark_ppd_file.ppd -p B2338dw -E -u allow:all -v usb://Lexmark/B2300%20Series

the printer was finally there, but prints were not going out.

Code: Select all

lpstat -v

gave me the clue about file permissions mentioned above.

Just for information I opened a bug about it.

Did you really mean:

Code: Select all

/usr/libexec/cups/backends/usb

Mine is as follows:

Code: Select all

$ ls -l /usr/libexec/cups/backend/usb
-rwxr-xr-x 1 root root 35520 Feb 19 23:26 /usr/libexec/cups/backend/usb

There is NO "s" in backend.
