Here are the few printers I've got working so far with Debian...
HP printers and P1102

Canon Pixma E510
Brother DCP-J315W
CUPS admin

so the spool directory likely needs creating!
if those are present already then they might need to belong to the lp group

the other error that will occur if your user is not added to the lp/lpadmin group is that logging into the admin page with your user name will return a failed unauthorized page.
Enable a user to resume a printer
To prevent CUPS asking for authentication of a user when using resume or pause printer in Cups Admin...
- Open cups http://localhost:631/admin/
- click on Edit Configuration File
- under the printer you need to give access to and the sections with "Resume-Printer Enable-Printer Disable-Printer..." either:
- remove the authorisation, e.g. under "AuthType Default" remove the line,
Require user @OWNER @SYSTEM
- Or, if that fails, just remove the items from that limit list which you don't need to login to do
Then save the file.
If you'd like a desktop shortcut button to re-enable a printer, then you can use,
Or, Openbox menu item with the command, `sudo cupsenable printer-name`
and edit the /etc/sudoers file
sudo visudo
add the line:
