no lpr or lprng file in /etc/int.d/

My printer is behaving randomly except for the test page. It always works well on test page.

Sometimes it works well on all applications.

Sometimes it works on Chrome, chromium, but not on Firefox and pdf readers.

Next time it works well on all browsers and not on pdf readers.

Next time it does not work on any application except test page.

But, it always show led signal whenever I give print command. And also it shows printing and printed, without being printed.

The printer is HL-L2321D and I am following instructions from their site. The instructions are from here and here.

So, I tried on installing all related drivers. One of the last instruction is to restart lpr or lprng in /etc/int.d. But I don't have such file.

To get lprng init script you have to install corresponding package by

sudo apt-get install lprng
