COPIER is a program intended to be used with an HP ScanJet scanner and an HP
LaserJet printer to provide the function of a desktop copier.  Documents are
scanned and printed at a resolution of 300 dpi.  Page size defaults to
Letter, but may be changed to A4 with a command line switch.

COPIER requires approximately 1MB of available disk space for a temporary
raster image file.  This temporary file (COPIER.TMP) is normally created in
and then deleted from the current directory, but may be directed elsewhere
(to a RAM disk, for example) by using the DOS SET command to create a
"TEMP=d:\path\" environment variable.

When COPIER is executed, the following options are displayed:

<ESC> = Quit   <RET> = Copy   <P> = Print

Pressing the ESCAPE key terminates the program and returns control to DOS.

Pressing the RETURN key scans the document in the scanner and reproduces it
on the printer.

Pressing the P key prints another copy of the last document scanned.

Several command line options are available to modify COPIER's operation:

/A  = Enable automatic background
/Bn = Set brightness level (-127 to +127) : Default = 0
/Cn = Set  contrast  level (-127 to +127) : Default = 0
/Dn = Use dithering (0 = Coarse, 1 = Fine, 2 = Bayer, 3 = Vertical Line)
/I  = Invert image (black/white)
/M  = Mirror image (left/right)
/Pn = Set printer port to LPTn (1 to 3) : Default = PRN
/Sn = Set scaling factor (4 to 100) : Default = 100
/2  = LaserJet II compatibility mode
/4  = Set page size to A4

Notes:
(1) /A option is ignored if dithering is used.
(2) /Cn option is effective only when dithering is used.
(3) /Bn and /Cn options are ignored if /A option is used.
