From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

CUPS mirror image printer setup (lemmy.ca)

I'll need to mirror print stuff regularly (flip across the vertical axis), and I'm trying to make the process convenient.

The manual way to mirror print would be by invoking lp, e.g.

lp -o mirror myfile.pdf

Invoking lp would work for images, PDF, ps etc. But but for application (open office draw) files. Unfortunately, I don't see an obvious way to mirror print within the application itself.

I'm thinking of setting up a mirror printer in CUPS that would automatically apply the -o mirror to any documents that hit it.

I suspect this would require some tinkering with CUPS filters - I'll dig into it sometime.

I can't be the only one who's needed this at some point in time.

Has anyone here done something similar? Looking forward to your thoughts!

It is certainly useful for some use cases such as network print servers (I have a dedicated lxc container on the network to do this) and custom conversions of pages (during my digging, I learned about companies using a CUPS network printer to watermark every document being printed).

I'm not an expert by any means: it is definitely a useful tool in certain cases, but oh man.. the documentation was a bit hard to figure out for me!
