Printer driver package for PostScript Printers
Usage/Setup: Install this Snap, go to http://localhost:8000/ (or to http://localhost:8001/, ... if you have more than one Printer Application installed), click "Add Printer". Detailed instructions: https://github.com/OpenPrinting/ps-printer-app#installing-and-building
If you want to use a PostScript printer under any Snap-supporting operating system this is the software to use. It already support several thousands of different printer models and if your PostScript printer is not explicitly supported, you can add its PPD file (PostScript Printer Description file, comes with the printer's Windows/Mac/Linux drivers) or resort to generic PostScript support.
If your PostScript printer is from HP you can alternatively use the HPLIP Printer Application (https://snapcraft.io/hplip-printer-app). Use the HPLIP Printer Application if you want to print and scan simultaneously on a multi-function device and PostScript Printer Application if you want to be able to query your printer for its installed accessories (like extra trays, finisher, duplex, ...).
This Printer Application emulates a driverless IPP network printer (IPP Everywhere) for each physical printer set up with it, so your computer's printing environment discovers it automatically and makes your printer(s) available for printing. Like on a physical network printer there is a web interface for administration, here especially also for adding and configuring printers. You find it with your browser under https://localhost:8000/. Note that currently printers have to get added via the web interface to use them. In the future, there will be utilities to easily find non-driverless printers and find the correct Printer Application for them.
With modern printers usually being driverless IPP printers, classic printer drivers, installed under CUPS by its web interface or a printer setup tool, are deprecated and replaced by Printer Applications which emulate driverless IPP printers as this one.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap is available for Red Hat Enterprise Linux (RHEL) 8 and RHEL 7, from the 7.6 release onward.
The packages for RHEL 8 and RHEL 7 are in each distribution’s respective Extra Packages for Enterprise Linux (EPEL) repository. The instructions for adding this repository diverge slightly between RHEL 8 and RHEL 7, which is why they’re listed separately below.
The EPEL repository can be added to RHEL 8 with the following command:
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
sudo dnf upgrade
The EPEL repository can be added to RHEL 7 with the following command:
sudo rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
Adding the optional and extras repositories is also recommended:
sudo subscription-manager repos --enable "rhel-*-optional-rpms" --enable "rhel-*-extras-rpms"
sudo yum update
Snap can now be installed as follows:
sudo yum install snapd
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again or restart your system to ensure snap’s paths are updated correctly.
To install ps-printer-app, simply use the following command:
sudo snap install ps-printer-app
Browse and find snaps from the convenience of your desktop using the snap store snap.
