Yes, the printer can switch between PostScript and HP emulation through the
use of an escape squence. There is one big advantage that the TI has over most
other brands and that is, it will go busy during (no lost of characters) while
switching modes. The only problem is you will either need to send out the
initialization code out each time you send a document or keep up with what mode
the printer is in before you send your document. Switching between mode does
slow down the effective output, not the printing speed. It might be a good
idea if you spool all your PostScript files together send them and then spool
your HP LaserJet files.

The TI is not a real work horse but your sure can not beat the price for a
full PostScript printer. By the way, the HP emulation mode uses real HP fonts
and not the Adobe Type I fonts and you can down load soft-fonts to the on
board memory. I do recommend that you get an additional 1 megabyte of RAM
bring the total up to 2.5 megabytes. This speeds up the assembly of PostScript
text with graphic images.
