I recently converted to a Mac computer and use Apple's iWork 08 instead of Microsoft Office. Now I can't send documents. I tried sending them on Pages via Gmail, but it doesn't seem to work. Can you help? Tim, Sheung Wan DQ: By controlling hardware and software development, Apple can do things Microsoft cannot. Microsoft works with makers, such as Dell and Lenovo, to agree on hardware items for its Windows operating system. Apple must also think about the millions of Windows users. It must be compatible with various applications, including Office. With Apple's iWork, often you are not dealing with files so much as with folders. You can't send this document through Gmail because folders are more difficult to send than files. If you have a document open in Pages, click on the File menu and you will see an item called 'Export'. When you release the mouse, you get a range of file formats to choose from. The first is PDF and the second is Word; save the document as a Word file. That should allow you to send it. I have a laser printer and a colour inkjet printer. But when I look for paper, I get confused about what I am supposed to use. It has something to do with the paper's weight. Can you explain? Name and address supplied DQ: There is an article on Wikipedia that covers paper density (en.wikipedia.org/wiki/Paper_density). Essentially, everybody outside the United States uses grammage, which is a metric measure of paper weight. It simply means the 'grams per square metre', often abbreviated to 'gsm' or 'g/m?'. You can find 500-sheet packages of A4 paper bearing the standard description of something like '80 g/m?'. The higher the number, the greater the weight. Often, lightweight paper is used for printing drafts of documents. A heavier weight of paper is then used to print the final product. For colour, it may depend on the printer. Most inkjet printers today do a far better job using glossy paper, but you may want to experiment to see which type better suits your purpose.
