同一段用Printer.Canvas...的代码在Windows 2000下打印正常，在Windows Me下却
提示 Printer is not currently printing，为什么？（打印机打印其它文档时都正常）。

抱歉，上述原因是我使用了函数GetDeviceCaps(Printer.Canvas.Handle,LOGPIXELSX)
引起的。不知在uses中缺了哪个引用单元？

Printer.begin
doc;
try
GetDeviceCaps(Printer.Canvas.Handle,LOGPIXELSX);
finally
Printer.Canceldoc;
end;
