Includes Print Server strategy
Sharing computer may be direct-cable to print
device or via Ethernet (or even via another share)

IP Address and IP hostname

–
Probably gets one from DHCP
To see address, print internal test page, or read
off of LCD
Probably want to change it, to protect from DHCP
changes. (When not?) 4th octet above 231.

Ways to change: LCD control panel. HTTP
interface. Old HP network tool. HP tool built into
recent driver installers.
Also change Method
Consider using name instead. Either cryptic
generated one, or make your own. “LABLASER”
for example.

Logged on as admin
Add as local, clear checkbox for Auto detect PnP
Can reuse existing TCP/IP port?
Or create new port

Or create new port
Give IP numerical address of print device
OR give hostname of print device
After creating port, Add Printer wizard continues
All users should see that printer
(suspend PPT, do live demo of Wizard)

Printer Shares: Installing




Install as local on hosting computer.
Share from there. Choose share name
systematically.
On other computers, install as Network
Printer. (In MS sense.)
Short cut: Browse or Search to print share,
right click, choose Install or Connect.

Problem: many student users
Answer 1: Let them run Add Printer Wizard
Answer 2: Deploy short cheap locationspecific script (example on next slide)
Answer 3: Site-wide automatic, sophisticated
script.

set objNet = CreateObject("WScript.Network")
objNet.AddWindowsPrinterConnection "\\I5560w000021798\HP2000C"
' objNet.SetDefaultPrinter "\\I5560w000021798\HP2000C"

Corresponding Pros and Cons of Ether and Share
Share
Ethernet
Host must be up
No issue
Computational burden on
host
No issue
Can use VM or disk to
spool on host
Limited to onboard RAM,
queue backs up on
sending machines

Hybrid Printer Strategy
Share
Ethernet
Print device and host must Anywhere
be close
In multiuser context, must
install for each user
Admin installs once for all
Fussy host name to type
or fussy network browse
Fussy IP address to fiind
and change
Manage queue, trace
sender
Little or no management

Hybrid Printer Strategy


Print Device uses Ethernet Interface
One Host connects to Print Device over
Ethernet
–


If possible, takes sole control of it
That Host shares the Printer
Other computers use the share



Is it a panacea? Best of both worlds? No.
Is it the worst of both worlds? No.
Advantages:
–
–

Can install by script
Can manage queue
Disadvantages:
–
–
–
Host must be on
Processing burden on host
Need local install for each user


Those disadvantages not so big if the host is
your server
–
–
–
Server is expected to be up
Server is less likely to be overburdened
Host name is not so obscure, and there’s just
one. Helpful both for manual Wizard use and
script.

Managing Printer Use




Ethernet print device – little or no control
Share – watch queue
Hybrid (or Print Server) – manage like Share
Separate teacher and student submissions
–
–
Multiple printer entries for single print device
Use domain user/groups to control printing
permissions
