lp printing doesn't work

[Gary Roach <gary719_list1@verizon.net>]

Hi all

Debian Stretch
KDE Desktop
HP Officejet Pro 8600 printer
Wireless connection

For some reason, my lp print command doesn't work. My lpoptions file in 
/etc/cups/lpoptions is:

> Default Officejet_Pro_8600_N911a media=DRAFT  page-bottom=54 page-left=54 page-right=54 page-top=54


If I run lpoptions on the command line I get:

  copies=1 device-uri=socket://192.168.1.5:9100 finishings=3 
fitplot=true job-cancel-after=10800 job-hold-until=no-hold 
job-priority=50 job-sheets=none,none marker-change-time=0 media=DRAFT 
number-up=1 page-bottom=54 page-left=54 page-right=54 page-top=54 
printer-commands=AutoConfigure,Clean,PrintSelfTestPage printer-info='HP 
Officejet Pro 8600' printer-is-accepting-jobs=true 
printer-is-shared=false printer-location='Local Printer' 
printer-make-and-model='HP Officejet Pro 8600, hpcups 3.16.11' 
printer-state=3 printer-state-change-time=1503877259 
printer-state-reasons=none printer-type=10522652 
printer-uri-supported=ipp://localhost/printers/Officejet_Pro_8600_N911a

A you can see, my printer is specifically called out. But if I run lp 
<file> I get:

lp: Error - no default destination available.

I've tried to reinstall cups_client but that didn't help.

I have an almost identical system that is setup the same way and is not 
having the problem.

Anyone have an idea what's causing this.
