Writing Tips
Today's pens are available with various types of writing tips. Writing tips come in medium and fine points. Fine point tips are ideal for users who have small handwriting and work better for sharper and more precise handwriting. Medium point tips are best suited to users with large handwriting and are best used for general-purpose writing.
Projector Screens
Remember to consider all relevant factors before deciding which projector screen to purchase. What are the dimensions of a room -- is it long and narrow, or wide and shallow? Consider the lighting of a room--- are there a lot of windows where ambient light may leak in, or is it a home theatre in a basement with no windows? How many people will be in the audience -- is this meant for a conference room, a boardroom, or a family room? What type of projector is going to be used -- it is critical to match aspect ratios, and to ensure that the projector's beam will be bright enough to maximise the screen's fabric.
Injet & Laser Printers
Inkjet printers cost significantly less than laser printers, though it can be argued that the price of consumables, especially ink, needed to maintain an inkjet result in significantly higher costs than the consumables needed for a laser printer.
Monitor Cleaning
Newer computer LCD and flat screen monitors tend to be made of plastic. If an ammonia-based cleaner is used on these surfaces, the ammonia will gradually eat away at the plastic, leaving it brittle and deteriorated. Also, alcohol will cloud and discolour the screen over time.
