[mod.amiga] Canon InkJet Driver -> Quadjet Driver

eraps1@ulowell.UUCP (01/20/87)

Hi,
After looking around for a QuadRam Quadjet driver for a couple of
weeks with no luck, I decided to see if the Canon Inkjet driver
could be used (it is floating on numerous BBS's).  The answer is
yes (with a small modification).

The only difference (that we care about) is a change in the graphics
command sequence.  The Canon uses an <ESC>X, while the Quadjet uses
an <ESC>H.  Unfortunately, the <ESC>X sequence never appears in the
driver (it is placed in the buffer a character at a time).  Examination
of the Canon driver revealed 15 'X'es.  The second one (trail and error)
is the one we want.  To patch the driver, simply write a short program
to copy the Canon driver a character at a time to the (new) Quadjet Driver
file and replace the second 'X' as it goes by with an 'H'.  That's it.

If you are feeling adventurous, change the printer driver name inside
the driver with "filezap" (from one of the Fish Disks).  The name is
in the second record and must be terminated with a NULL.  
(Aside: filezap is a great program, but it lacks [my version anyway] a
 way to search for strings/characters/hex codes, or we could do the
 whole patch inside it).

						Good Luck,
