DEF_OUTPUTWIDTH = 0;

DEF_OUTPUTWIDTH is a constant that represents the default value used for the TIdLPRControlFile.OutputWidth property. DEF_OUTPUTWIDTH is assigned to the TIdLPRControlFile.OutputWidth property in the constructor for the control file. 

In the Line Printer Daemon Protocol, the WIDTH command can be used to specifiy the number of output columns required for output produced using the Print formatted file, Print file leaving control characters, and Print file with 'pr' format commands in the LPR protocol. 

DEF_OUTPUTWIDTH and TIdLPRControlFile.OutputWidth are ignored for all other LPR commands that generate output.
