TI850.DRV
|
|
|
|
This is a relatively simple driver with no complex functions/capabilities.
|
|
|
|
The resolutions are 120 x 72 and 60 x 72 dpi.
|
|
The original driver only has 120 x 72 but the 60 x 72 was
|
|
easy to add.
|
|
|
|
All Y moves are made by linespacing commands (Esc 3 n)
|
|
|
|
There is no X move command. X moves are made by 10 cpi spaces
|
|
and graphics moves.
|
|
|
|
The only paper source available is Tractor Feed.
|
|
|
|
The only fonts supported are Pica 10 cpi and Pica 5 cpi.
|
|
The TI850 command set allows for a Pica 16.7 cpi font, but
|
|
there are X move problems created by roundoff errors. This font
|
|
was not used in the original driver, so it was not included here
|
|
either.
|
|
|
|
The printer can only do a draft quality text.
|
|
|
|
The printer can do bold type, but no italic, underline, strikeout or double underline. Italic is not supported and the underlines and strikeout are done with GDI calls.
