The Custom Character Conversion Command can be used to resolve some problems in
printer data streams. An example might be to remove a special command character in
an existing data stream that was used by your previous printer hardware. Without
changing your data stream, these special characters can either be removed, converted
to Nulls, or converted to other sets of data to accomplish what is required.
An example of this might convert a Skip Command used by an older generation printer
to multiple Carriage Return / Line Feed commands. You could also store a PCL5
command in our SIMM and call it with one character in your data stream. Only one type
of conversion is permitted at any particular point in time, but the function can be modified
within a data stream multiple times.
The conversion information is stored in NVRAM and is retained through power off /
power on cycles. This means you could send the command one time and all future print
jobs would be converted. Special precautions are required if printer fonts and macro’s
are downloaded to your printer. This might require you to disable the function during
downloads and re-enable prior to your print data.
&%STCxx[yy...]$
xx is a double-byte character to convert - the following characters are not allowed:
&, %, S, T, C and $.
yy is a double-byte string to convert to - can be 0 to 16 characters long
$ command terminator
Example:
&%STC1E0D0A$ – sets the convert character to 1E - the printer will replace any 1E
character in the data stream with 0D 0A (carriage return, line feed)
&%STC1E$ – replace 1E with nothing - simply removes all 1E characters from the data
&%STC00$ – turn character conversion off
