I already setup pdfprt  to be paused.
Then I checked for ~/.lpoptions as a normal user, and didn't find it.
It appeared that /etc/cups/lpoptions still pointed to the old printer
(neither pdfprt, nor gray-deskjet).
So I tried to do:
# lpoptions -d gray-deskjet
lpoptions: Unknown printer or class!

Then I tried 'lpoptions -h localhost -d gray-deskjet' and it worked.
This changed the default printer in /etc/cups/lpoptions.

However, lpstat  still says it cannot connect to server, and for
example enscripting a text file fails as well:
$ enscript todo
lpr: error - scheduler not responding!
[ 1 pages * 1 copy ] sent to printer

$ enscript -P gray-deskjet todo
lpr: error - unable to print file: server-error-service-unavailable
[ 1 pages * 1 copy ] sent to gray-deskjet

$ enscript -d gray-deskjet todo
lpr: error - unable to print file: server-error-service-unavailable
[ 1 pages * 1 copy ] sent to gray-deskjet

In fact, I just deleted pdfprt, and the situation still has not
changed (ever after restarting cupsd).


I just ran lpstat with strace, and I notices something that I
suspected all along, it tries to connect to my old print server:

connect(4, {sa_family=AF_INET, sin_port=htons(631),
sin_addr=inet_addr("10.1.1.4")}, 16) = -1 EHOSTUNREACH (No route to
host)

I hope no-one minds if attach the whole output from strace here.
