I would like to mention 2 issues that do not work in my Z18 implementation and that do work well in Z17.3 ;
1/ Printing with my Epson SX445SW is well recoginized and defined as my default printer. However when I try to print a document, the task is launched and quasi immediately turns into Pause mode. I click from the printer panel the "go" button, it runs the task but get back to Pause again. When I send a test print it does print it correctly. The document that does not get printed is an image .png. I tried printing directly from the image, and than I tried via LibreOffice_writer by inserting the image. I tried a standard text printing, same issue. I use a multi boot system with Z18, Z17.3 and Windows 10. In Z17.3 and Windows 10 everything works fine.
2/ The screendump function. A so practical Zorin function ! In Z18 it does work OK EXCEPT in one particular case. This case is that of a pop-up selection window when I am in an application, whatever it is (File or Writer, or...), eg. Save as in Writer, where I want to choose the standard Office 365 format that is .docx instead of standard .odt. A pop-up window appears to select the format I want, and while the pop-up is displayed, the screendump function does not work at all. It seems not even triggered. This is valid whatever selection pop-up is displayed, not only in Writer. This function in Z17.3 does work perfectly.
I would be grateful if anybody tells me a workaround from within Z18 (well my workaround is to get in Z17.3...) for both issues.
I always had difficulties with the integrated screenshot function, even in Zorin 17, because I couldn't capture context menus with it. That's why I use ksnip, which allows you to set a capture delay . There are surely many screenshot programs that offer this.
I love to use Synaptic Package Manager, for finding specific driver & component software, that may not be found, in the software store itself. I typed in Epson, & this is what I found. Make sure the bottom one is installed at the very least.
Looks like it might be related to how Wayland handles modal windows. On Z18, the built-in screenshot tool sometimes just ignores pop-ups for me too, so I switched to Ksnip with a short delay — works without issues. Another workaround is logging into an Xorg session if you need to capture pop-ups often. I didn’t run into this back on Z17, so it could be a quirk introduced in the Z18 environment.
Screenshot for me is Spectacle every time, but works best in Plasma Desktop. For Zorin use Shutter instead. It should be in Software.
In respect of your printer issue, @wesoliv429 is correct about the escpr package (Zorin 18 is based on Ubuntu 24.04):
" To install the driver for an Epson SX445W printer on Ubuntu 24.04, follow these steps:
Install the required package: Use the terminal to install the printer-driver-escpr package, which provides support for many Epson inkjet printers, including the SX445W. Run the command:
sudo apt install printer-driver-escpr
Add the Printer: After installing the driver, open the "Printers" settings in Ubuntu. The system should now detect your Epson SX445W. If it doesn't appear automatically, use the "Add" button to manually add the printer. Select the appropriate driver from the list, which should include options for Epson models like the SX445W.
Alternative Driver Source: If the standard package does not resolve the issue, you can download the specific driver directly from Epson's website. Navigate to the Epson support page for your printer model (SX445W) and download the Linux driver in .deb format. Install it using the command:
sudo dpkg -i <path-to-downloaded-driver-file>.deb
If dependency issues arise, resolve them with:
sudo apt --fix-broken install
Troubleshooting: If the printer is detected but prints nothing, try removing the printer from the settings and re-adding it after installing the driver. This method has been reported to resolve intermittent printing issues on Ubuntu 24.04. Ensure the printer is properly connected via USB or Wi-Fi and that the network settings are correct.
With regards your .png issue, have you tried saving the image as a .jpg? Icve had issues with laser printers when I was working that didn't want to print certain images.
Ive been using Synaptic for a long time. But yep, im guilty of appreciating your manuals. So you keep tickling those keyboard keys, and ill keep reading them.
Hi everybody and many thanks for the many answers given. I saw some which I will dig into more in detail.
1/ For printing funny enough, today I printed a pdf document and it printed OK (that was not a .png though which I will try when I have further checked your answers),
2/ Concerning the screendump issue, I understand from reading that this is embeded into Ubuntu 24.04/Gnome 46 that modal screens do not trigger/allow standard screendump. Don't quite understand why. I might get into an alternative screendump function that many of you proposed.
Disabling the modal dialogs didn´t help to be able to make screenshots of context menues. You can only do this with a time delay.
Edit: You can add a custom keyboard shortcut for the tool gnome-screenshot, then screenshots are taken with this program and not with the default screenshot tool when you press key print.
e.g.
name: gnome-screenshot
command: gnome-screenshot --interactive
key: Print
I would love to know how to replace the screenshot app used in the quick settings of the taskbar with gnome-screenshot! I really miss the delay function.
Edit: I read that this is not possible because the screenshot function that Zorin uses by default is integrated into the desktop and is neither an app nor a gnome extension that can be replaced.
The older gnome-screenshot tool that was used in earlier Zorin versions has been replaced to ensure better Wayland compatibility. Since I have only tested the gnome-screenshot tool under Xorg so far, where it worked perfectly, I will test it later under Wayland.
Edit2: I tested gnome-screenshot under Wayland, and it works.
I noticed that the integrated screenshot function for some apps like the Nautilus context menu or some context menues of gnome settings only does not work under Xorg (pressing key print does not open the screenshot tool), but under Wayland it works perfectly.
