Re: HPLIP: equivalent of ptal-devid wanted

I use "lpinfo -v" to get available "hp://..." URIs. To associate 
/dev/usb/... devices to them, I do "getusbprinterid.pl <device>" and 
find the "hp://..." URI which contains the "MODEL" or "MDL" field of the 
detected ID string right after "hp://usb/" and, if available, matches 
the serial number.

To determine whether a printer is supported by HPLIP already before 
installing/starting HPLIP I match the '<model name="...">' in 
/usr/share/hplip/data/xml/models.xml against the "MODEL" or "MDL" field 
of the detected ID string. The HPLIP RPM I have made in a way that 
/usr/share/hplip/data/xml/models.xml is in a separate RPM and this 
separate RPM is always installed. printerdrake installes the rest of 
HPLIP when it detects a supported printer.
