Legacy Overprint Control Panel Options
The Print on CR control panel option is intended for use by customers whose applications
embolden characters by using a CR-only method to selectively reprint all or parts of a line. This
option was present in the previous firmware release, but only with the options of
Off (same as
below), and On (equivalent to the new Double Strike setting). This option can be accessed as
follows:
CONFIG Î Codes Î Print on CR Î Off / Double Strike / Bold
Off Ignore bolding, print as regular text (Default setting)
Double Strike Print line, then backup to reprint (bold by overstriking)
Bold Print line once, bold portions printed with enhanced "bold" style
For example, the application may embolden the word "bold" in the following sentence by
sending:
This is bold<CR> bold<CR><LF>
"Double Strike" corresponds to the previous POCR=ON setting. With "Double Strike" selected,
bolding is accomplished by re-striking the characters at the same dot positions. This requires a
1-line backup after printing each <CR> pass; some applications use many passes to print a single
bolded line, so printing throughput may be reduced accordingly.
With "Bold" selected, bolding is accomplished by rendering the bolded characters twice, one
with a small offset to create a "shadow" effect. The resulting print is thicker and thus appears
darker. This is the same technique used with the "bold" character attribute selected via
emulation escape sequences.
