Fonts and Character Attributes on the LA310 MultiPrinter

12.6 Download Font—DECDLD

Table 12–7 DECDLD Erase Control (Pe)

Pe Erase Control

0 Erase all characters in all set sizes in the speciﬁed font buffer.

1 Erase only the characters that are loaded.

2 Erase all characters in all set sizes in all font buffers.

3 Erase all characters in the speciﬁed set size and font buffer.

The LA310 Multiprinter allows you to load fonts for three different densities

into a font buffer. You must use a Pe value of 3 when downloading more than

one density into a font buffer to prevent previously loaded fonts in a different

density from being erased.

The LA310 font ﬁle download capability is limited by the following

considerations:

• Full cell fonts (Pu = 2) are not supported by the LA310 MultiPrinter. A

DECDLD protocol selector with a Pu value of 2 will be ignored by the

LA310 MultiPrinter.

• The LA310 MultiPrinter supports 2 font buffers, each supporting Draft,

High-Speed Draft, and Near Letter Quality 2 (NLQ2) densities. The

Near Letter Quality (NLQ1) density for the downloaded font ﬁle can be

generated algorithmically by the printer from the downloaded Draft font

ﬁle.

DECDLD control string error handling differs from the description in the

Command Dictionary. If the Dscs string is found to be invalid, the remainder

of the control string is ignored, but the effects of any parameters (such as Pe,

Erase Control) will take effect.

12.7 Slant

The LA310 MultiPrinter supports the Select Graphic Rendition (SGR) attribute

for slant by algorithmically slanting the characters.

Slant is performed in one pass with double horizontal resolution. In draft and

HSD modes, printing is slower in slant than in normal draft mode. Slant is

performed in the same way for NLQ1 and and NLQ2 modes, but without any

impact on the normal printing speed for these densities.

See SGR in the Command Dictionary.
