Alan is correct, you want a laser printer. Buy remanufactured toner cartridges and you will get about 90 - 95% of the performance of OEM toner cartridges at about 1/2 the cost. ALWAYS print in draft mode. Use grayscale too if your eyes aren\'t going bad.
An alternative that I am hooked on -- not because I am \"green\", but because I am \"cheap\": download the sheets and save as a .pdf to your computer...then view the sheets on you PC. The obvious disadvantage is that you have to have a laptop and lug it to the track, if you want TG by your side at post time. It\'s a hassle at first, but you might be able to live with it.
I\'m going out to buy one of those tiny notebooks for $300 tonight -- I\'ll let you know how the sheets look on one of these little PCs.
