UNIX Host Setup LPR
10 - 3
After adding the queue entry to the printcap file, check the queue setup using the lpc status com-
mand.

You can now print to the queue using normal lpr commands.

10.2.1 Notes about LPR
There are several important things to note about the LPR printing method:
• Because of the way the LPR protocol is typically implemented on the
host, the processing options and the banner page are sent after the job
data itself. Because of this, the RapidPrint 500 will print a banner page
at the end of a job, and cannot support most of the LPR options. If it is
necessary to have the banner page at the beginning of the printout,
install and use the RTEL software.
• The RapidPrint 500 cannot print multiple copies of the print job when
the -#x lpr option is used.
• If banners are not needed, they can be disabled on custom services
using the following RapidPrint 500 commands:
Figure 10-5: Disabling the LPD Banner Page
• By default, a formfeed is added to the end of each LPD job to force a
page eject on laser printers. If this formfeed is not wanted, it can be dis-
abled using the following RapidPrint 500 command:
Figure 10-6: Disabling the LPD Formfeed Characteristic
• Many LPR spoolers are not intelligent about using multiple queues on
one host. Queues on the print host must use separate spooling directo-
ries. If only the default directory is used, data from multiple queues
can be intermixed or sent to the wrong RapidPrint 500 service.
• No special purpose input or output filters can be used when printing
via LPR. If this functionality is necessary, use the named pipe interface
program in the RTEL software.
