This printer can handle the following weights: 64 g/m² - 255 g/m².
For office use the standard is 80-90g 100g maximum for more official documents as they are less fragile and more qualitative.

Here are some papers I can offer you:

Epson Inkjet White Glossy (500 x, A4, 90 gsm) which has a satin finish

HP Premium FSC (500 x, A4, 80 gsm) which is a bit thinner and matte

Papeteria Copy paper, from 5 pieces (500 x, A4, 90 gsm) which is also 90g with a good price-performance ratio. :)
