Format
RESL resolution;
Parameter
resolution:
300 [dpi], 600 [dpi] or 1200 [dpi]
Function
The RESL command switches the resolution of the printing system between 300 dpi,
600 dpi, and 1200 dpi.When this command is received, the image data currently
remaining is forcibly output on paper. This does not affect the current unit of measure,
but the system’s memory will be reconfigured, causing PCL resources (fonts, macros,
patterns, and symbol sets) which have been downloaded into RAM to be purged.
The printing system’s resolution setting enabled by this command is reset to default
(FRPO N8), if a command which results in reset (RES, FRPO and SEM) is received.
Actual resolution may be decreased to 300 dpi even though printing resolution is set to
600 dpi or 1200 dpi when there is insufficient memory because a duplex unit is installed
and duplex mode has been set or because the video memory size has been increased for
page protection.
Printing resolution cannot be switched from 300 dpi to higher resolutions for the
following emulations: line printer, IBM ProPrinter, Diablo 630, EPSON LQ850.
