| Sending print jobs from Unix/Linux to a HP JetDirect print server |
|---|
|
Problem:
How to let Unix/Linux processes send print jobs to a networked HP printer? Setting up printcap and spooling is near impossible without running X on the server.
|
Solution:Newer JetDirect adapters supports FTP printing, simply upload the file you want to print.
Alternatively, send the print jobs directly to the printer via the LPR/BSD protocol on port TCP/515. This ancient protocol is supported even by the oldest JetDirect cards and can be used in several different ways.
1. Use LPRng (by far the simplest approach)
" cat printme.txt | lpr -h @192.168.1.2"
2. If you are using Perl, download and install Net::Printer from www.CPAN.org
3. Write your own TCP client that speaks LPR/BSD (The protocol is very very simple)
