Good to see a refresh of maciprpi! I'm curious what base OS you're using now?

It's also encouraging to see that you're on a supported and secure release version of netatalk now.

May I ask what it would take for you to migrate to the netatalk 4.x release series? Is there some technical reason holding you back? Please note that the 2.4 release series will receive security patches until September 2025, but after that we plan to EOL it.

A few benefits of netatalk 4.x over 2.4:

- Coexistence with Samba (avoid risk of filesystem metadata corruption)
- AFP 3.4 compliance
- Extended Attributes metadata (more reliable than AppleDouble)
- Bundled and improved macipgw (such as a macipgw.conf configuration file)
- Tons of bug fixes

Ultimately it's your call. But I'm invested in setting you up for success in adopting the latest and best supported version.

I can launch Chromium in a remote session like XRDP (rdesktop) or X2Go. I will test with monitor and keyboard too. Maybe that is the problem?

About printing. I have to be honest... I never have printed from / or with help of the MacIPRpi! So... would be nice to know how to do this, so I can add it.

papd.service is always started at boot.

@mactjaap Regarding Fizzbin's problem, do you remember if you had all CUPS dependencies installed when you built netatalk?

It is possible to build papd without CUPS, at which time you get a traditional BSD line printer daemon interface instead.

/usr/lib/cups/backend/pap is what I had to get setup on my v5 to get CUPS working with AppleTalk Printing, the file I'm using is something I found on the Internet and hacked on until it surprisingly worked, at least for what I wanted to do (print to an AppleTalk only LaserWriter from modern machines using the Rpi as a print server). I was hoping the newer Netatalk build would come with that file fixed up.

I'm not familiar with a /usr/lib/cups/backend/pap file. Is it a plain text or binary file? This is not something that Netatalk creates or touches directly.

macipgw@macippi:/usr/lib/cups/backend $ cat /usr/lib/cups/backend/pap
#!/bin/bash
#
# Usage:     pap job user title copies options [filename]
#            pap
#
# Important: This backend supports device discovery -- just call it without
#            parameters to see whether it works correctly on your system.
#
# Main use:  CUPS backend to drive AppleTalk printers. Tested with CUPS
#            1.1.14/1.1.15/1.1.19 (version 0.1.4 tested with CUPS 1.7.5)
#
# Notes:     Device URIs have to have the following format (special chars
#            in URL encoding): pap://zone/printername/printertype
#            Normally you shouldn't care about that since the backend lists
#            all available devices correctly formatted when asked by the
#            CUPS scheduler.
#            Don't forget to adjust $devicetypes and $formfeed to your needs!
#            When used with Darwin 7.0 (MacOS X 10.3.x) you might want to
#            change the shell to /bin/bash in the first line due to problems
#            with the encoding routines for the device uri (perl -e call)

#
# Changes
#
# 0.1.4 (11 Apr 2017):
#        Changes by M. Amolsch as per forum discussion with Thomas Kaiser:
#        - changed shebang line to /bin/bash
#        - updated NetatalkBinDir to correspond with the Netatalk path in
#          recent versions of Ubuntu and Debian
#        - specified separate TimeoutDir and corresponding call to use with
#          coreutils in recent versions of Ubuntu and Debian
#        - added line end to printer name query
#
# 0.1.3: - query AppleTalk devices by default for their "Product name" to
#          let CUPS assign the correct PPD automatically (this is achieved
#          by setting FullDeviceDiscovery=TRUE)
#        - set the default netatalk installation path back to /usr/bin
#        - set a timeout value of 15 seconds when querying printers for
#          their "Product name"
#        - massive performance improvement in larger networks with many
#          zones when doing device discovery while $FullDeviceDiscovery
#          set to TRUE (due to parallelizing the queries)
#
# 0.1.2: - fix the inability to deal with printers with slashes in their
#          names
#        - report wrong netatalk installation dir --> ${NetatalkBinDir}
#        - minor documentation improvements
#
# 0.1.1: - fix some documentation errors and default values
#
# 0.1.0: - first official release (22 Mar 2003)

# Customizable settings:
#
# The devicetype variable specifies for which devices to look for (eg.
# LaserWriter, DeskWriter, ImageWriter). If you want to lookup more than
# one device at a time, write them separated with colons, ie.
#
#     devicetypes="LaserWriter:DeskWriter"
#
# For all devicetypes use "=" instead. But be warned: this will also find
# macs, servers, serial numbers and the like
 
devicetypes="LaserWriter"

# specify whether or not to send an additional form feed (DeskWriters
# seem to need this. TRUE means send the ff

formfeed=FALSE

# When you want to use this with Netatalk, then specify the path to
# the $BINDIR (do a search for nbplkup, eg.). You might also want to set
# $FullDeviceDiscovery to TRUE to let CUPS guess the correct PPD for the
# devices by asking them for their "Product" name...
# Additionally you can let the backend collect exact pagecounts from
# PostScript printers that correctly implement a back channel (answering
# the backend's questions). If you use dumb AppleTalk print servers do
# NOT set this option
#
# Note: This last option is still not implemented

The pap backend file is only if you want to print to a pap only LaserWriter from Linux.

Hmm, all of this shouldn't be required. If CUPS is aware of your printer, you should only have to put

cupsautoadd:op=root:

in papd.conf and that's it.

See this guide that I wrote some time ago: https://netatalk.io/docs/Print-Server

macipgw@maciprpi6:/ $ cat /usr/local/etc/papd.conf
# PAP print server daemon configuration (Netatalk 2.x)

# See the `papd.conf' manual page for examples.

# Uncomment the following line to share all CUPS enabled printers.

There are at least three other PAP backends available on the net (Duncan Gibb [based on Rupi]: download · instructions · info · Rupi's original [info] · archive with Rupi's backend and docu [next to other stuff] | Derrik Pates: download · description · setup 1 · setup 2 | SRZ Berlin: download and description), but the one from Thomas Kaiser is the most advanced and automated one. The original can be found here. To meet the development status of today's Linux systems, emaculation.com is hosting an updated version that is downloaded and installed with the following entries.
