Try printing the error message with perror() to find out what "some reason" is. As a stubborn programmer would say, don't give up until you know why it's not working. Smilie

NAME
cupsaccept/cupsreject - accept/reject jobs sent to a destination SYNOPSIS
cupsaccept [ -E ] [ -U username ] [ -h hostname[:port] ] destination(s) cupsreject [ -E ] [ -U username ] [ -h hostname[:port] ] [ -r reason ] destination(s) DESCRIPTION
The cupsaccept command instructs the printing system to accept print jobs to the specified destinations. The cupsreject command instructs the printing system to reject print jobs to the specified destinations. The -r option sets the reason for rejecting print jobs. If not specified, the reason defaults to "Reason Unknown". OPTIONS
The following options are supported by both cupsaccept and cupsreject: -E Forces encryption when connecting to the server. -U username Sets the username that is sent when connecting to the server. -h hostname[:port] Chooses an alternate server. -r "reason" Sets the reason string that is shown for a printer that is rejecting jobs. CONFORMING TO
The cupsaccept and cupsreject commands correspond to the System V printing system commands "accept" and "reject", respectively. Unlike the System V printing system, CUPS allows printer names to contain any printable character except SPACE, TAB, "/", or "#". Also, printer and class names are not case-sensitive. Finally, the CUPS versions may ask the user for an access password depending on the printing system configuration. SEE ALSO
