Switching the Print Resolution
Because the printing systems with the 1200 dpi resolution support print at 300, 600, 1200
dpi, the printing system provides an FRPO command to establish a default at either level
of resolution.
For fine 1200 dpi resolution, command:
!R! FRPO N8, 3; EXIT;
For 600 dpi resolution, command:
!R! FRPO N8, 1; EXIT;
For 300 dpi resolution, command:
!R! FRPO N8, 0; EXIT;
When the printing resolution is changed between 1200 dpi, 600 dpi, and 300 dpi, the
printing system loads the PJL current environment values.
In addition to the FRPO N8 command as explained above, printing systems that permit
the resolution to be set at either 300, 600, or 1200 are provided with the RESL (change
RESoLution) command which switches the resolution on the fly. For details about this
command, refer to PRESCRIBE Commands Command Reference.
The amount of available printing system memory will determine whether the 600/1200 dpi
default can be effective. If factors such as resource protection, duplexing, and raster mem-
ory reduce memory too low, then the printing system will remain at 300 dpi resolution.
