This is what I found in some old driver for a LBP-8; maybe it is the same for the LBP-4 :

*** Init-code :

CHR(27)+";"+CHR(27)+"[?8h"+CHR(27)+"[?32h"+CHR(27)+"(' 1"                                           

*** Have some large font :

CHR(27)+"[0"+CHR(32)+CHR(75)                                               

Note that a Canon printer of this type is a lousy thing to control. Worst isn't possible ! (sorry Canon).

Send the above to the printer, preceeded with ??? " " (raw mode).
Don't use Set Printer On before this, or you may get anomalies (??? is just a printer-command already).

Sure hope this helps.
