When transferring raster graphics data, each line of raster data must be
prefixed by the command:
<ESC> *bnW
wherengives thenumber ofdata bytesto follow(the maximum is255 before
anothersuch command issent). This data mustfollow the compression rules
setin the previous command. For instance, aTIFF image interpreted in any
way other than the TIFF format will produce very strange results! Repeat
sending lines of graphics data, prefixed by the above command, until the
whole image has been transmitted.

Tosignal theend ofgraphic datatransmission, sendthe followingcommand:
<ESC> *rB
There are no parameters. The LaserPrinter 4111isnow in text mode.
Apro,grainminghint:move your print position in dot increments whenever
you’re dealing with graphics. It’s easier than trying to calculate column-
widths or decipoints.
The RasterHeight command specifies the height in pixels of the next raster
graphic (between the startgraphics and stop graphics commands).
<ESC> *rnT
Thevalue of nmustbe non-negative; if necessary, it istruncated to the value
of(logical page length) -(y coordinate of cursor). This command causes all
rasterrows after the specified height to be clipped (disregarded), even if n=
O.It forced the cursor position to advance vertically by nrows, even if less
than nrows are transferred. The area maps to either opaque or transparent
depending on the source transparency mode.
