First, it is not "Ec" (Letters E and c) but an escape (ASCII 0x1b).
Second, the correct way to switch from PJL to another
language is to say something like
print "@PJL ENTER LANGUAGE = HPGL2\r\n"
Probably it's a good idea to ensure you're in PJL mode
before giving PJL commands.
print "\e%-12345X at PJL\r\n at PJL ENTER LANGUAGE = HPGL2\r\n"
Maybe it could be even possible to go the whole way round to
PJL, from there to PCL and then to HPGL.
print "\e%-12345X at PJL\r\n at PJL ENTER LANGUAGE = PCL\r\n\e%1B"
You can see some output like that when you give the command
$ echo "showpage" | gs -q -dBATCH -dPARANOIDSAFER -dQUIET -dNOPAUSE -sDEVICE=ljet4pjl -r600 -sOutputFile=- - | less
I will not tie myself to an exact answer because I do not
know which printer model you're using. Just play around
until you found a solution that works.
