Printer Tweaking Options
These are the options used to customize the operation of foo2hp for a particular printer.
-u xoffxyoff
Set the offset of the start of the printable region from the upper left corner, in pixels [0x0].
-l xoffxyoff
Set the offset of the end of the printable region from the lower right corner, in pixels [0x0].
-L mask

0 don't send any logical clipping amounts
1 only send Y clipping amount
2 only send X clipping amount
3 send both X and Y clipping amounts
-O c,m,y,k
Alignment of CMYK in rows. The default is 0,0,0,0.
-P Do not send START_PLANE codes on monochrome output. May be needed by some black and white only printers, such as the HP LaserJet
1000.
-A AllIsBlack: convert C=1,M=1,Y=1 to just K=1. Works with bitcmyk input only.
-B BlackClears: K=1 forces C,M,Y to 0. Works with bitcmyk input only.
-X padlen
Add extra zero padding to the end of BID segments. The default is 16 bytes.
Debugging Options
These options are used for debugging foo2hp.
-S plane
