Network printer error

[Brandon Butler]

Dear Sir/Madam

It is a pleasure to meet you and I hope you are doing well.

My computer runs Ubuntu 20.04.1 and I experience an error in CUPS
regarding being unable to resolve the IP address belonging to the
network printer which uses the default drivers from when Ubuntu
automatically detected and added that network printer after
installation. The printer model concerned is an EPSON WorkForce
WF-3640 and is connected via Ethernet and assigned a static IP address
in the printer's firmware settings and the router's DHCP allocation
configuration.

The error concerned only occurs when my computer remains suspended for
multiple days and that is resolved by restarting my computer which
will reconnect to the network printer and attempt to complete all
queued jobs during the next start or logging in and retrying the job
if the queue is cleared in advance.

I appreciate any responses to my enquiry.

Kind regards

Brandon Butler
