Quick Report in 1920*1080 resolution plus 125% When the above display setting environment is，The proportion of "Preview Print" will be incorrect.(too big or too small)，But the actual printing is normal.，If you want to correct，It is necessary to modify the qrprntr.pas file of Quick Report in the compilation environment，There are two ways to correct it。

when installing the program，"No more space left on device" appears，Check with df -h，is /tmp full。
My /tmp dependent partition，is with / same magnetic region，and / there is room，So you can temporarily increase the space of /tmp by remounting the command。
df -h /tmp #查詢 /tmp 佔用空間。 sudo mount -o remount,size=15G /tmp/ #將 /tmp 大小改成 15G。 df -h /tmp #確認 /tmp 的佔用 % 是否改變。
To empty /tmp，The following commands can be executed：
sudo rm -r /tmp/*

// 0: 表示定義整個括號裡面的第 0 個變數要採用此日期格式。
// 以下為兩個變數的範例。
string s = String.Format("At {0}, the temperature is {1}°C.",
DateTime.Now, 20.4);
Console.WriteLine(s);
// Output similar to: 'At 4/10/2015 9:29:41 AM, the temperature is 20.4°C.'

Delphi menus seem to always have fonts that go back to default (8, Tahoma) The problem，Questions from abroad，but no solution。The temporary solution I can think of at the moment is to set a function key (Can be set as hotkey)，Let user encounter small font size，Reset font size by yourself。(During testing, the menu font can be changed back to the default value by changing the Windows display size percentage)
procedure Tmainform.N93Click(Sender: TObject); begin Screen.MenuFont.Size := 12; xxxxxx.BringToFront; // 改變畫面焦點，以刷新選單畫面。 end;
