I bought an HP2840 Color LaserJet, and wanted to use it in Postscript mode, but CUPS in Linux doesn't automatically upload document required fonts. I call this script from rc.local so that it runs when I start my computer. Make sure your printer is on first. The script sends data to the JetDirect port 9100.
#!/bin/sh
#The next line restarts using tclkit \
exec `which tclkit` "$0" ${1+"$@"}
