User-Defined Pattern Command - HP PCL 5 Reference Manual

User-Defined Pattern Command

The User-Defined Pattern command provides the means for
downloading the binary pattern data that defines the user pattern.
Default
Range
The value field (#) identifies the number of pattern data bytes that
follow the User-Defined Pattern command. In addition to the binary
pattern data, there are eight bytes of pattern descriptor (header)
information included in this pattern data. The format for a 300 dpi
resolution header is shown in Table 13-3, below.
Table 13-3
Byte
With the introduction of the LaserJet 4 printer, user-defined patterns
can be printed either 300 or 600 dpi resolution. X Resolution and Y
Resolution fields have been added to the header information included
in the previous header. The format for the new header is shown in
Table 13-4, below.
