This may sound obvious, but consider traceroute. A 20+ second delay almost surely indicates a grossly overloaded system, somewhere in the path from A to B. You cannot do much about it until you locate it. Ignore my suggestion if you are routing over lots of DSL lines, in which case you are stuck.
We had remote printers on the other side of DSL lines from their print servers. Printing was painfully slow. Created local remote print servers, the problem went away.

cancel
cancel(1) User Commands cancel(1)
NAME
cancel - cancel print request
SYNOPSIS
cancel [request-ID...] [destination]...
cancel -u user... [destination]...
DESCRIPTION
The cancel utility cancels print requests. There are two forms of the cancel command.
The first form of cancel has two optional arguments: print requests (request-ID) and destinations (destination). Specifying request-ID with
destination cancels request-ID on destination. Specifying only the destination cancels the current print request on destination. If desti-
nation is not specified, cancel cancels the requested print request on all destinations.
The second form of cancel cancels a user's print requests on specific destinations.
Users can only cancel print requests associated with their username. By default, users can only cancel print requests on the host from
which the print request was submitted. If a super-user has set user-equivalence=true in /etc/printers.conf on the print server, users can
cancel print requests associated with their username on any host. Super-users can cancel print requests on the host from which the print
request was submitted. Superusers can also cancel print requests from the print server.
The print client commands locate destination information using the printers database in the name service switch. See nsswitch.conf(4),
printers(4), and printers.conf(4) for details.
OPTIONS
The following options are supported:
-u user The name of the user for which print requests are to be cancelled. Specify user as a username.
OPERANDS
The following operands are supported:
destination The destination on which the print requests are to be canceled. destination is the name of a printer or class of printers
(see lpadmin(1M)). If destination is not specified, cancel cancels the requested print request on all destinations. Specify
destination using atomic, URI-style (scheme://endpoint), or POSIX-style (server:destination), names. See Notes for informa-
tion regarding using URI-style or POSIX-style destination names with cancel. See printers.conf(4) for more information.
request-ID The print request to be canceled. Specify request-ID using LP-style request IDs (destination-number).
user The name of the user for which the print requests are to be cancelled. Specify user as a username.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
non-zero An error occurred.
FILES
/etc/printers.conf System printer configuration database
$HOME/.printers User-configurable printer database
ou=printers LDAP version of /etc/printers.conf

NOTES
URI-style and POSIX-style destination names (server:destination) are treated as print requests if destination has the same format as an LP-
style request-ID. See standards(5).
Some print servers send cancelation notification to job owners when their print jobs have been cancelled. This notification usually comes
in the form of an email message. Cancelation notices cannot be disabled on a Solaris server.
When IPP is in use, the user is prompted for a passphsrase if the remote print service is configured to require authentication.
