Hi Ivan.
As you understand, I don't like your answer. If you are right I have wasted money.
But some of the specifications of the printer: Ram: 197MB, Rom: 5MB, Disk: 360 MB, Fonts: 137. There should be enough processor power for my jobs.
When starting to print a message is displayed: Generating PostScript file. This is done only for the first page. When printing I can see that the processor utilization is about 0,5 %, and that is next to nothing. Writing this answer takes about 4 %. That means that the software emulation must be a very light one.
I get the same behavior printing from OpenOffice - one page -waiting -one page - waiting. I printed a letter without pictures and colors and that was faster, but still waiting between pages.
Now I ask Alex Taylor to comment this.
