The Send Block box contains the command which processes or sends one or more blocks (or rows) of graphics data.
For the Diconix 150 Plus printer, the Quadruple-Density 8-Bit Graphics command (ESCZn1n2d1 . . . dn) processes multiple blocks (that is, an entire bitmap) at the 320 x 96 dpi resolution. The arguments n1 and n2 specify the total number of bytes of graphics data: n1 is the remainder when this number is divided by 256, and n2 is the quotient. The arguments d1 thru dn represent the actual bytes of graphics data.
To specify the Quadruple-Density 8-Bit Graphics command, type the following in the Send Block box:
\x1BZ%l
For the HP LaserJet IIP printer, the Transfer Raster Data command (ESC*bnW) processes a single block of raster data at the specified resolution. The argument n specifies the count of bytes of raster data.
To specify the Transfer Raster Data command, type the following in the Send Block box:
\x1B%dW
