This is the line I get when I run lpinfo -m | grep e709n

drv:///hpcups.drv/hp-officejet_6500_e709n.ppd HP Officejet 6500 e709n, hpcups 3.16.3

Sorry about getting back late, do a lpinfo -l -m instead.

The function dealing with the printer driver enumeration is the following:

library/cups_lpadmin.py#L503-L547

So far I've seen lpinfo -l -m only return the results in the following format (mac, 14.04 and 16.04):

Model:  name = drv:///sample.drv/zebracpl.ppd
             natural_language = en
             make-and-model = Zebra CPCL Label Printer
             device-id =

if in above format, it should be able to parse and create the appropriate driver list

This looks similar to ansible/ansible-modules-extras/pull/3350; changing

kv = map(str.strip, kv)

at line 540 to

kv = tuple(map(str.strip, kv))

fixes this traceback for me.

[HP41]

That seems to have fixed it!
Thanks @pghmcfc !
Sorry for the late reply!
