Why? There's still nothing like printed documentation when you're
learning a new subject. Or perhaps you'd like a PDF document to view on
Here's the quickest way to create a PDF from any Perl documentation on
your system. For example, let's do the CPAN module SQL::Abstract:
pod2pdf --pagesize=letter `perldoc -l SQL::Abstract` > /tmp/SQL_Abstract.pdf`
Now you can view or print that. I find print 2-up pages, double-sided
(4 total pages per sheet) is a handy and space-saving yet still
readable. You might find it useful to reduce the PDF margins and let
okular manage the actual 2-up physical margins later:
pod2pdf --margins 18 --pagesize=letter `perldoc -l SQL::Abstract` > /tmp/SQL_Abstract.pdf
The margins parameter is in printer's points (1/72 inch) and 18pt =
¼inch (0.635cm). You can also specify
--left-margin as well as right,
top, and bottom margins individually.
When printing several PDFs together, you may want to suppress blank
pages. This is important when using double-sided or 2-up printing. To
join several PDFs together for printing, you can use:
pdfunite a-in.pdf b-in.pdf output.pdf
If you are having difficulty printing documentation that contains
cpanm App::pod2pdf Paper::Specs
For some reason, on Fedora 15, CUPS wasn't starting on bootup.
Print jobs were just being silently dropped. I tried this:
$ **lpq** lpq: Unable to connect to server.
Hmm... That's not right.
$ **sudo service cups start** Redirecting to /bin/systemctl start
Oh... they changed the administration command for some reason. I
couldn't find anywhere in the menus (or the discombubulated,
disorganized mess that substitutes for menus in Gnome 3) a GUI for
selecting startup services. Didn't we have that back in RedHat 4?
Anyway... a little digging uncovers that the simple
inexplicably, has been replaced by the more jargon-laden
command, so the 'new' way is now:
$ **sudo systemctl start cups.service**
OK that got it going.
lpq sees CUPS and print jobs actually print.
Now to change it permanently:
$ <strong>sudo chkconfig --list</strong>

systemd services. SysV configuration data might be overridden by native

Another frustration. This functionality is now rolled into the
command. Perhaps that's nicer, but where's the GUI interface for this?
I guess I could use webmin, but gosh it seems Gnome should have one.
Here's what it reports:
$ **systemctl status cups.service** cups.service - CUPS Printing
Service Loaded: loaded (/lib/systemd/system/cups.service; disabled)
Active: active (running) since Thu, 20 Oct 2011 08:19:58 -0700; 7min
ago Main PID: 16104 (cupsd) CGroup: name=systemd:/system/cups.service └
16104 /usr/sbin/cupsd -f
OK, it's disabled at startup. here goes:
$ **sudo systemctl enable cups.service** ln -s
'/etc/systemd/system/printer.target.wants/cups.service' ln -s
'/etc/systemd/system/sockets.target.wants/cups.socket' ln -s
Ah, there we go.
Please, Fedora and Gnome -- where's the GUI administration tools for
