I need to install DYMO software for labelwriter 450, but i can't... any help?

To install Dymo 450 LabelWriter on Debian Systems - Ubuntu, Raspibian, you might need first: (helped me to compile drivers, advice from : http://ubuntuforums.org/showthread.php?t=1502581 )

sudo apt-get install libcups2-dev libcupsimage2-dev gcc g++

Then you want to do install dymo linux sdk (both links work at 2016-05-14):

• http://www.dymo.com/en-US/dymo-label-sdk-and-cups-drivers-for-linux-dymo-label-sdk-cups-linux-p--1
• http://var.dymo.com/US/resources/sdk/linux/

Then you unpack it, compile and install driver:

./configure
make
sudo make install

Later I've added driver via cups web interface like any other driver, choosing right ppd file. (example project : https://www.hmazter.com/2013/05/raspberry-pi-printer-server-for-labelwriter and another: https://gist.github.com/gwpl/6d6c1457b4d1f6b778917a2f7c3c57fd ).

Finally, I share via network Dymo 450 LabelWriter(s) attached to Ubuntu and Raspibian with other Linuxes (including Archlinux) and I've found that to make printing via network (e.g. ipp:// and ipps:// ) to work, I need to schedule printing (of pdf, png, whatever) add -o raw to lpr command. You will see example of -o raw in https://gist.github.com/gwpl/6d6c1457b4d1f6b778917a2f7c3c57fd and https://askubuntu.com/a/748035/31300 .

Finally references for installing and using Dymo 450 under Linux:

• https://ubuntuforums.org/showthread.php?t=861781&page=6
• http://www.taklischris.info/varietas/use-your-dymo-printer-on-ubuntu

14.04 and later

Open the terminal and type:

sudo apt install printer-driver-dymo

You need to get the correct drivers for CUPS, the Linux printing system. As far as I can tell, you can download them here:

The answer by Grzegorz kinda works, but there is an issue in the official DYMO sources which prevents it from building on the latest version of CUPS. I found a patch on this Ubuntu forum post which contains the fix for it.

The post's instructions were:

git clone https://aur.archlinux.org/dymo-cups-drivers.git

Then copy that files inside the folder of driver, and finally:
* patch -Np1 -i cups-ppd-header.patch
* ./configure
* make
* sudo make install 

Basically, several files are missing this line, which makes it impossible to build:

#include <cups/ppd.h>

I made the change against the official version 1.4.0.5 copy of the source and put it in a repository for others to use: https://github.com/Kyle-Falconer/DYMO-SDK-for-Linux
