/*

* Version which sents raw data to the printer, which enlarges and centers.
|
|
* Works for monochrome and four band IM_TYPE_CMYK images. Uses putc instead of
|
|
* fprintf. Sents data straight to the printer. If enlargement, it is full and
|
|
* x and y ratios are the same (aspect ratio is not changed)
|
|

|
* Helene Chahine, July 95

|
|
* JC 4/8/95
|
|
* - small tidies and bug fixes
|
|
* - now does 1, 3 and 4 band
|
|
* - resets printer after use
|
|
* JC 1/9/95
|
|
* - colour reverse mode added
