I have CUPS and some 
options (such as N-up) 
seem to be always enabled 
even though I don’t pick 
them in LLPR.

There may be some local options defined in your ~/.lpoptions 
file, which is manipulated by the lpoptions command. These 
options will always be used if not overridden by LLPR settings. 
To get rid of all options for a printer, run the following 
command, replacing “printer” with the name of the queue: 
lpoptions -x printer

I configured a printer to 
print to a file, but I get 
“Permission denied” errors.

Most printing systems will not run as the super-user but as a 
special user (usually “lp”). Therefore, make sure that the file 
you have chosen to print to is accessible to the user owning 
the spooler daemon.

On my PCL (or SPL) 
printer, I sometimes get 
error messages printing 
instead of my document.

Unfortunately, some Unix applications may generate non-
compliant PostScript output that may not be supported by 
Ghostscript, or even the printer itself in PostScript mode. You 
can try to capture the output to a file and view the results 
with Ghostscript (gv or ghostview will allow you to do so 
interactively) and see if you get error messages. However, 
since the application is at probably fault, contact your 
software vendor to inform them of the issue.

When using the printer in 
EPSON Dot Printer 
Environment, sometimes I 
can not get the output I 
want.

Change the emulation to EPSON in the Config tab in the 
Remote Control Panel. For detailed information about 
selecting printer settings in the Remote Control Panel, see 
page D.4.
