Resolving hp-printer issues in CentOS
To resolve HP printer issues in CentOS try following steps:
- yum -y update hplip cups
- Reboot the machine
- As root user run system-config-printer and delete all old printers for the same device. Add a new printer and try to print test page.
- If system-config-printer fails to add printer then first delete all printers using 'system-config-printer'. Then try to use 'hp-setup' command as root.
- If this also fails again delete all printers and use 'hp-setup -i' command as root. Try to get latest drivers for printer from hp website. If internet is accessible through proxy then 'export http_proxy=<proxy-url>' before running 'ht-setup -i'.
- If still no sucess then try to get latest hplip sources from official website and install latest hplip from source.
