Workaround: before printing set the AutoSizeRows = false, then you can set it again to true

private void radButton1_Click(object sender, EventArgs e)
        {
            if (!this.radGridView1.Columns["ImageColumn"].IsVisible)
            {
                int height = this.radGridView1.TableElement.ViewTemplate.Rows[0].Height;
                this.radGridView1.AutoSizeRows = false;
                this.radGridView1.TableElement.RowHeight = height;
            }

            this.radGridView1.PrintPreview();
            this.radGridView1.AutoSizeRows = true;           
        }
