Increasing printing speed

[M.Thomas]

Dear All,
Are there any possibilities to increase the printing speed in a printer? From HPUX server side
Please help me
Thanks in advance

Ask yourself "Could I help someone who asked so vague a question?".

If this is a network printer, it's possible that a faster network connection will help marginally but normally the computer can transmit data to the printer MUCH faster than it can be printed. It's also possible there is a speed/duplex mismatch between this printer and its corresponding switch port. Now, if the output is complex graphics then perhaps something can be done but if and only if more data are provided.


One rather simple test is to modify the printer interface file to send data to a file rather than the printer. (Of course, this assumes that you are using the lp subsystem --- yet another tiny detail you neglected to mention.) If the data can be "printed" to a file rather quickly then the bottleneck is not the host computer but the printer itself or the network link.

Thanks a lot Stephenson for your quick respone

Hi Stephan
We are using network printer & lp subsystem
Can you tell me how to modify printer interface file to send data to a file rather than the printer.

We will modify the interface file for queue "myprinter".

1) cd to /var/spool/lp/interface
2) cp -p myprinter myprinter.safe # so we can restore the original
3) vi myprinter

You will probably see a line similar to this:
$REALMODEL $job $user "$title" $copy "$options" $files | $HPNPF $HPNPFOPT 2>>$LOG > /dev/null

Comment this line out by placing a '#' at the beginning of the line and insert a similar to this:

$REALMODEL $job $user "$title" $copy "$options" $files | cat - > /tmp/myprinter.out

Save the file and try your lp command. There is no need to do an lpshut/lpsched after these changes.
