This is somewhat off topic, since it's a different Linux system 
(PCLinuxOS) and my scanner works
perfectly. It's part of an Epson WP-4530. But I ran lpstat -t and it 
doesn't say anything about the
scanner function. It only shows the printer and its network address. (I 
have set my printers with
static ips.)
Here's the output:

[doug at linux1 ~]$ lpstat -t
scheduler is running
system default destination: hplj-pro-m201
device for hplj-pro-m201: socket://192.168.1.29:9100
device for WP4530: socket://192.168.1.26:9100

WP4530 accepting requests since Thu 09 Mar 2017 09:26:34 PM EST
printer hplj-pro-m201 is idle.  enabled since Sun 12 Mar 2017 02:10:06 
PM EDT
         Ready to print.
printer WP4530 is idle.  enabled since Thu 09 Mar 2017 09:26:34 PM EST

So what was the purpose for running that command?
