Problem

Solutions: The customer has two questions about the Brother M-1724L printer:
1.      Why do retrieved WP 5.0 files print strangely from WP 5.1 when Center, Extra Large, and Bold are used together ([Cntr][Extra Large][Bold])? The printer turns the Bold attribute off after the first word in the heading.

2.      Why is Line Draw not supported in WP 5.1 when it was in WP 5.0 on this same printer?

Answer 1:
In the WP 5.1 driver, the Load and Select Strings for the 5, 6, and 7 pitch (Large) fonts have a variable called "bold4" in each Select Font string. This variable causes WP to change bolding methods from an Auto Bold to WP's Bold on a Separate Pass. You could try taking the bold4 variable out of these font select strings, and see if the printer will correctly handle bolding such large fonts automatically.

Answer 2:
As for the Line Draw, according to the printer driver writer, the printer simply does not have any Line Draw characters built into it. In WP 5.0, developers had to define a separate font specifically for Line Draw, and the character map for that font (Dot Matrix 1/60) contained bitmap information for all of the Line Draw characters.

The developer said that they are trying to get away from supporting things that are not inherent in the printer's capabilities. Also, the WP 5.0 Line Draw font only worked in 10 pitch because it was hard-coded for a certain size. Besides, the driver writers are told to let WP's .DRS handle everything it is capable of, rather than taking up space in the driver.

Since it must be frustrating for customers not to have a capability that they had before, they can try the following two ideas to get Line Draw working:
1.      Convert the WP 5.0 .PRS file
2.      If the converted 5.0 file creates problems with other features, then copy the Dot Matrix 1/60 character map from the converted 5.0 file to the WP 5.1 file. From here you have two choices:
      A)      Create a Line Draw font in the WP 5.1 driver and assign the Dot- Matrix 1/60 map to it, or
      B)      Use Text In/Out to copy the various bitmaps from the Dot-Matrix 1/60 character map to the character map being used by all the 10 pitch fonts. That way, you won't need a separate Line Draw font because the Line Draw "characters" will exist in the default text font.
