Sometimes you have to make suitable adjustments and/or apply a second filter to get a result that pleases.
You might get a better result, still using G'mic
1. Repair -> Remove hot pixels then 2. Repair -> scanned documents.
However.
Going back to your printing question. Want to print DIN4 (A4) Your image cropped to A4 proportions is about 850 x 1275 pix @ 150 ppi Which gives a print size of 146mm x 215mm not A4 210mm x 297mm
You could scale up to 210 mm wide but the image will still be 150 ppi - printing quality not so good. Resize again to 300 ppi which is good for printing and quality gets worse.
A better way is convert the image to a vector. There are on-line tools for this but I use linux. SVG is attached.

If you want to try this:
1. Open a new blank A4 image File -> New and from the drop down template A4 this gives the correct size @ 300 ppi. Good for printing.
2. Import the SVG File -> Open as Layers with size in pixels as above. Remember Gimp is a raster editor and works in pixels
3. That’s it, add anything else as a new layer. Save your work as a Gimp .xcf When complete Export as a png or Tif for a printer.
