Re: Epson printer driver installation problems following the macOS 27.0.1 update
Due to the limited technical details provided, particularly the exact model of your Epson printer, it is difficult to offer precise and reliable information about driver compatibility or the most appropriate solution.
However, the symptoms you describe suggest that the issue may be related to printer software compatibility, the macOS printing system, or the way your Epson printer is configured following the recent update.
You mentioned that, since updating your 24-inch iMac to macOS 27.0.1, the printer will not print normally unless you reset the printer in System Settings for every print job. An Apple advisor subsequently recommended installing the Epson printer driver, but you have been unable to install the software compatible with your updated operating system.
There are several steps worth considering before attempting further installations:
Confirm the exact Epson printer model and macOS compatibility
Epson provides different drivers and software packages for different printer models. A driver that worked with an earlier version of macOS may not be compatible with your current operating system. Visit the official Epson Support website and select your exact printer model to check for compatible drivers, software updates, and installation instructions.
If Epson has not yet released a driver for your particular printer and macOS version, repeatedly attempting to install an older driver may not resolve the problem.
Check whether a separate driver is actually required
Some Epson printers support Apple's built-in printing system, including AirPrint, and may not require a separate manufacturer driver. If your printer supports AirPrint, this may provide a useful alternative to installing an Epson-specific driver. However, the appropriate option depends on your printer model and its supported features.
Check the printer configuration in macOS
Open Apple menu >> System Settings >> Printers & Scanners and select your Epson printer. Check that the correct printer is selected and that the printer is not paused or showing an error.
If you repeatedly have to reset the printer before each print job, this is not normal operation. The underlying cause could involve a corrupted printer queue, a software compatibility issue, or a communication problem between the iMac and the printer. Repeatedly resetting the printer for individual documents should not be necessary once the issue has been resolved.
Consider removing and re-adding the printer
If the printer continues to malfunction, removing the printer from Printers & Scanners and adding it again may help rebuild its configuration. If the printer supports AirPrint, try selecting AirPrint when adding it back.
Before removing the existing printer, make a note of its current configuration, especially if you use special settings such as duplex printing, paper sizes, or particular print-quality options.
Avoid repeatedly resetting the entire printing system without further diagnosis
Resetting the printing system can remove existing printers, queues, and related settings. Although it can sometimes resolve persistent printing problems, it is best treated as a troubleshooting measure rather than a routine step before every print job. Since you have already been advised to reset the printer repeatedly, it would be preferable to identify the underlying cause instead of continuing with that workaround.
If the Epson driver still will not install
The exact installation error is important. For example, the solution may differ if the installer reports that the software is incompatible with this version of macOS, cannot be opened, is blocked by a security setting, or completes installation without making the printer work.
Because the problem began after a macOS update, it is also worth asking Epson Support to confirm whether a compatible driver is available for your specific printer and operating-system version. Apple Support can help investigate whether the macOS printing system is functioning correctly.
Conclusion
The fact that printing worked before the update and now requires repeated printer resets suggests that the problem deserves further investigation rather than simply installing drivers at random. The most reliable next step is to identify your exact Epson printer model, establish which printing method it supports, and determine why the driver installation is failing. This should help distinguish a driver compatibility problem from a printer configuration or macOS printing-system issue.
To provide more specific guidance, the two most useful details would be the exact Epson printer model (for example, Expression, EcoTank, or WorkForce, including its model number) and the exact error message you receive when trying to install the driver. I can then help identify the appropriate driver or alternative printing method for your iMac.
