New to the Manjaro forum, also, it seems.
Welcome. 
System information is usually expected in order for others to help effectively – please see below 
for helpful directions.
Additionally, give specific information about the printers you are attempting to place in service – complete model numbers, their capabilities, and any other detail that might be useful to those wishing to help.
Tell us also what you have done so far in order to have the printers work as expected – this will help avoid duplication of steps you may have already taken – the more you help, the more the community might help in return.
Regards.
[Mini-HowTo] Provide System Information
Basic details provided by *-fetch type apps might give enough information for someone wishing to buy a computer, however, for Support purposes it’s best to ask your system directly.
Output of the inxi command will generate more useful and detailed information for those who may wish to help:
Suggested inxi command (use either):
|
|
inxi -zv8 |
(short-form) |
inxi --filter --verbosity=8 |
(long-form) |
Command output should be presented as pre-formatted text in accordance with forum guidelines. 
Running inxi within a chroot environment
- Add
--color=0 to the long-form command, or…
- Change the short-form command to
inxi -zv8c0

[Mini-HowTo] Present code or command output
Note: Grave accent (or, backtick) characters are used.
For inline code or to show a single command:
- please follow this simple example:
code here.
For multi-line command output:
- place text beween two rows of three (```) backtick characters to form a scrollable text box, or …
- use the </> button in the Compose window to achieve the same result.
The empty row between these rows of backtick characters is where to paste any multi-line command output (such as inxi).
An example of a pre-formatted text enclosure:
What is a Quark?
A. In Physics, an elementary particle and fundamental constituent of matter.
B. A character from the Star Trek: "Deep Space Nine" television series.
C. A soft, creamy, usually unsalted cheese traditional to central Europe.
