Daily Tip: Check For Compatibility If you create spreadsheets in Excel 2007, it's important to consider whether your workbooks include any functions or features that won't work when opened by those who use an earlier version of Excel. Fortunately, Excel 2007 allows you to check if a spreadsheet has issues with the .XLS file format. Open the workbook you want to test for compatibility, click the Microsoft Office button, select Prepare, and choose Run Compatibility Checker. At the next window, you can select the Check For Compatibility When Saving Workbook to run the checker each time you save the workbook. The Summary window will list any issues among Excel versions. Daily Term: letter quality
Letter quality means the same print quality as a typewriter. But with today's high tech printers, letter quality is significantly better than typewriters used to be, and now it's referred to as resolution. Laser, LED (light-emitting diode), and inkjet printers can all produce 300dpi (dots per inch) to 2,400dpi resolution, which is near photo quality. Even the old, now obsolete daisy wheel printers could produce letter-quality documents. In the old days, you could set the printers to generate letter quality, near letter quality, or draft mode. Using today's terminology, if letter quality is 300dpi, then near letter quality would be about 150dpi, and draft would be about 75dpi. The difference is the number of dots printed per inch on the page. More dots per inch mean a darker, more solid image. There is a new letter quality category of printing today called enhanced quality or enhanced resolution, which is controlled by the software. Printer manufacturers use this technique to sell printers with a true resolution of 600dpi as 1,200dpi machines because they can "enhance" the printer's output to 1,200dpi with software manipulation. Basically, the program tells the laser to place a fatter dot of ink onto a smaller grid, which overflows and bleeds together with the other dots to create the illusion of a higher resolution. If you are looking for letter-quality resolution today, almost every printer out there qualifies.
