Samsung EasyPrinter Manager under macOS 11 Big Sur

Well now we are talking about 2 different issues: the Samsung Easy Printer Manager, and the working of the Samsung printer under Big Sur 11.7 in general.

>You really do not need to use the Samsung Easy Printer Manager utility when the printer is configured to use Apple's AirPrint. If the printer is not AirPrint compatible, you are > at the mercy of HP to issue current drivers for the vesion of macOS you are using, and if they don't, old drivers probably will not work, or create bizarre results.

On the HP site, I found a "Samsung Universal Print Driver" dating from 2021. Should I try to install that?

In the instructional video,

https://support.hp.com/de-de/drivers/samsung-xpress-sl-c430-color-laser-printer-series/16462518

it is said that in the list of printers, you have to chose a model that reads 'multifunction'. But my printer is not multifunction, it's just a printer. Also, the video says, that I should NOT use the Air Print entry.

>I have also noted that the Samsung utility misbehaves when it cannot detect the Samsung printer on the same network segment. Have you assigned a static IP address to your printer, or are you using Dynamic Host Configuration Protocol (DHCP) that assigns a random IP address to the printer when it is powered up?

>I am using a reserved DHCP address for my laser printer that is a fixed IP address below those addresses dynamically assigned to the computers on the network.

I have no idea. I have never manually assigned an IP address to any printer, and would not know how to do it.

>What you should be able to do is print from any application. Can you do that?



No. I started trying with TextEdit, and I get these 2 alerts. It looks like I can not print from any application, if even TextEdit fails.

Addendum:

After all these trials, I find 3 printer icons in the Dock, showing numbers 10, 6 and 1. They seem to refer to print attempts and show a text 'Stopped - Can't open "/private/var/spool/cups/tmp/<a long alpha-numerical string.">'

Viking, thank you for this detailed instruction. Before I manage to allow the 1st app, the second alert appears, and the Printer Manager crashes. I have now tried to be faster by opening the prefs on beforehand. But now, even after re-launch of the Mac, I get one alert saying "The last time you opened Samsung Easy Printer Manager, it unexpectedly quit while reopening windows. Do you want to try to reopen its windows again?" Regardless if I chose re-open or don't, it re-opens, runs for some seconds, then crashes. The 2 other alerts appear at some time during this process, but I have no chance to allow them.

It looks like it is only the first time per day or so that the 2 alerts appear separately. I will try again tomorrow, being prepared to act fast.

Do you remember the days when Apple was user-friendly??

Thanks again for your instruction!

When I hold down the shift key while starting the Manager, I get no dialogue, it just crashes. If I start without the shift key, I get the "Last time..." dialogue. If I chose Re-open, it just starts without further alert, then crashes. If I chose Don't Re-open, the same.

In the meantime, I also tried to print a web page, both online and after download as SingleFile (Firefox). This is blocked, too. The Mac gives the alert for 2 files named 'rastertosec' and 'prefilter'. I can manage to do the Allow Anyway trick, but it has no effect. I can't print these files.

When I follow the Show-in-Finder command, I can see a difference between these 2 types of rejected files: Device2PCMon.app and ScrPrtMon.app are shown with the icon for apps that no longer will run under Big Sur; Raster-to-sec and Prefilter have icons that look like Unix Executable Files.

So what can I do to get a working printer again??

My printer model is the Xpress C430. By the way, it is connected to the MacBook via USB cable, so no IP address.

I have not intentionally downloaded, let alone installed any files from the HP site yet, I am surprised when I read that Firefox has downloaded them. I thought these were files that were on my Mac and had worked until the system upgrade. And 2 of them obviously are, Device2PCMon.app and ScrPrtMon.app, according to their icons.

I have sniffed around on the HP site, and could not find a printer with exactly the name as mine, but was directed to some that might be compatible - ? Yes I would appreciate if you would check if any of their drivers would work for me. And if not, I have to buy a new printer??

Sigh!

Things are getting worse. My Samsung Printer lacks the W in the model name, which probably stands for WiFi. The Ethernet exit seems to be deliberately sealed. (a plastic plate, that covers almost the entire aperture, hold in place by tiny connections to the rim of the aperture.)

I made a photo with the iphone to show you. I connect the iPhone to the MacBook using USB cable - and get a warning "Could not check for an update to the network provider settings for your iPhone. This device is no longer connected." And I am prompted to connect the phone using USB cable...

So what can I do with the iPhone? (12 mini)

And what with the printer?

Do you think I can just break the seal and hope there is a working Ethernet connection behind?

There is no Ethernet entry on the Macbook, but I have an adapter to one of the entries of the MacBook, those with the lightning icon. Would that work?

I'm going crazy...

I turned off Wifi to get around that network stuff, then connected the phone with USB cable. A Finder window is opened, showing Macintosh HD and Network, but no subdivisions of the Network after clicking the triangle, thus no iPhone. New windows with the same content keep popping up subsequently, I count 7 by now.
