With MacOS 10.15 "Catalina" Apple has completely converted the operating system to 64-bit. As a result, 32-bit software no longer runs. I had to delete a bunch of older games, but what's even more annoying is that the printer (Samsung ML2070) doesn't want to work properly anymore: it occasionally prints pages of special characters instead of the desired document. The old Brother color printer (MFC-490CW), on the other hand, has not been able to cope with the colors since Catalina. Both do not scan properly and show stripes in the scan, scan only halfway or the MacOS scanner software crashes. Affected but printers from all sorts of manufacturers seem to work be.
Solution 1: Update printer driver
Probably the easiest solution to get rid of printer problems is a new 64-bit printer driver for the respective printer. The problem with this: Many older devices in particular are no longer supplied with drivers by the manufacturers. Or there are no longer any MacOS drivers because MacOS has always supplied good drivers itself. With my more than 10 year old (!) MFC-490CW and many other models, Brother also delivers in an exemplary manner new drivers for Catalina: They are installed in just a few steps, the problems are then history and the printer does its job as a scanner and printer.
Solution 2: Use Airprint and solve printer problems on macOS
The situation is different with my much newer Samsung ML2070 multifunction device: sometimes it prints reliably, sometimes it just comes out of the printer nonsense. This is particularly perfidious with this model, as there is a page counter that announces when the toner is empty. That means: After the number of pages intended by the toner cartridge, it's over, even if thousands of pages with a single letter have been printed! I could spend hours ranting about manufacturers' overpriced and senseless proprietary rubbish of toner and ink, but I'll spare you that at this point. The important thing is to get the damn printer working again. Because for Samsung printers, HP has taken over the support – but does not provide any current drivers. However, Apple offers a list of Airprint-compatible printers, which also lists my Samsung.
Set up an AirPrint printer on MacOS
Luckily my ML2070 supports Apple's AirPrint feature. And that in turn works without a driver! Under iOS and iPadOS printing with the device is therefore not a problem, but a printer can also be set up via AirPrint under MacOS Catalina:
- Open the System Preferences in MacOS and select "Printers & Scanners".
- Click the plus sign in the lower-left corner of the printer list.
- The add dialog now shows you your printers on the Mac and in the network.
- Click on the desired printer. MacOS will now load the drivers.
- Since the printer does not work with the in-house driver, you must select "AirPrint" in the "Use" list.
- With a click on "Add" the printer is set up as an AirPrint printer under MacOS.
Conclusion: Annoying thing!
Even if it can be solved quite easily in many cases, the printer problem under MacOS 10.15 "Catalina" is really annoying. Especially since it didn't occur regularly, at least for me, but completely randomly. What particularly annoys me in my case is that HP does not ship updated printer drivers for my Samsung printer. The old Brother inkjet, on the other hand (which, by the way, has been working with China cartridges for 10 euro each for 1 years!), is dutifully supplied with drivers by Brother. When I next decide to buy a printer, I will therefore also include the long-term support. And Samsung won't come into my house at this point either.
Update 1: Specific solution for Samsung M2070 series printers
Unfortunately, your comments showed that the solution does not work for the Samsung M2070 printer mentioned in the article. I had severe problems myself when I wanted to print more than one page at a time. Luckily I was able to find a workaround after all: someone in the HP support forum has it posted a solution that seems to work, at least it worked for me:
- Download the latest driver from HP website, the file name is M2070_Series_Mac_PrinterDriver_V1.04.01.zip. I didn't find it on the HP site but found it here.
- Unzips the file.
- Install the drivers by double-clicking your (unzip folder)/PrinterDriver/MAC Installer/MAC_Printer/Printer Driver.pkg and following the installer.
- Ignore the two error messages with "Cancel", then the installation runs through.
- Now look again in the unzipped folder. Under (unzip folder)/PrinterDriver/MAC Installer/MAC Data/Printer Driver/10.6/PPD/gzipfile/ you will find a "Samsung M2070 Series.gz". Copies this to the desktop.
- Now go to "Printers & Scanners" and add your Samsung printer. Important: Do not select AirPrint under "Use", select "Other".
- In the following Finder window you can now select the "Samsung M2070 Series.gz". If it's grayed out, just copy it to another folder and repeat the steps from step 5.
- The printer will be installed. If further error messages occur, you can ignore them. The printer should then work again.
Update 2: Official Samsung drivers for macOS 10.15 Catalina are available
HP finally updated the driver packages for MacOS shortly before Christmas. The latest driver for the Samsung ML2070 mentioned in the article is available on the HP support site. Important: In order for the correct driver to be displayed, you must select "MacOS 10.15" as the operating system, otherwise the site only offers firmware updates or old drivers. After installation, at least this printer should work again, other models should now gradually receive updates.
Update 3: Give the printer a fixed IP
The printer problem dragged on for me as far as Big Sur. Both the iMac and the MacBook Air again didn't want to print correctly via WLAN, only cryptic characters came up again. No problem with iPhone and iPad. Ironically, there is no driver for the Samsung printer for Big Sur, installing the old driver was too delicate for me. So I came up with the solution which has already solved many WLAN problems for me: I deleted the printer from MacOS, gave the device a fixed IP address in the WLAN and then switched it off completely, i.e. unplug it. After switching it on, I then reconfigured the multifunction device in MacOS and lo and behold: So far everything has worked via AirPrint without a driver. TOI Toi Toi!
