This application (which is taken partially from your Report.java - Java
Tutorial) prints a 2-pages Tabel with some titles. In page number one
there should be a logo image, which I've substituted with a rectangle.
It doesn't give me any errors, but the first page take 3 minutes 20
seconds for spooling (note: without the logo image) and the second
2 minutes 20 seconds. My printer is an HP Laserjet 1100 perfectly
working, new, lastest model of laser printers, and my PC is a PENTIUM II
233 Mhz 128 Mb RAM. A similar table printed, for example with
MS Word 97 takes 20-25 seconds for both pages. I know these are
incomparable, but 3-4 minutes per page it's TOO MUCH for any
user!! The problem almost doesn't exist if I use an inkjet printer. I think the
problem is related with PCL printer (?).
