If the DECPSP (Proportional Spacing) command is set, the DECPSM
command sets the tabs and margins as usual, as listed in Side
Effects under DECSHORP in this chapter. However, the pitch is
stored and is not used until DECPSP is reset.
Notes to Software
This command is provided for backwards compatibility with older
printers only. Conforming software should not use DECPSP. Use
DECSHORP with Ps = 0 to select the natural pitch for the currently
selected font. Use other DECSHORP parameters to select pitches
other than the natural pitch.
Use DECPSM with monospaced fonts only.
DECPSP Proportional Spacing Mode:
When set, enables proportional spacing
of characters. When reset, selects monospaced printing.

Description
When a proportional font is in use and DECPSP is reset, the printer
prints characters on a monospaced grid.
DECPSP has no effect on tab settings.
DECRFS Request Font Status:
Requests a font report.

Description
The selective parameters for DECRFS are as follows:
0 = Requests both reports (same as 1 followed by 2).
1 = Requests font status (includes all built-in fonts, downloaded
fonts).
2 = Requests status of memory bytes available for downloaded fonts.
The host sends this command to request a status report of the fonts
available for printing, the memory available for font download, or
both.
The parameter Ps selects the type of font status requested.
Notes
Data fields are empty as explained in DECFSR.
Error Handling
If Ps is any value other than 0, 1, or 2, the printer ignores this
command.
