Can I print to my LaserJet 4 from 2 computers?

It has a serial and a parallel port on it.  I have my workstation
hooked up to the parallel port.  Can I also connect my Dell PowerEdge
600SC server to it also.

If so, can you give me link for the cable to go from the Dell
PowerEdge 600SC server to the HP LaserJet 4 serial port.  If possible,
i prefer to get it at newegg.com, but wif not no big.

Will printing over serial be a lot slower then parallel?

Can you also send me a link to a cable or innexpensive
adaptor/converter that would allow me to print to the HP's serial port
from a USB port on my laptop?

thanx in advnce

Ok this question covers allot. As far as I know the HP LaserJet?s that
have both serial and parallel cables can not do both at the same time
(I tried). In order for you to switch from one computer to the other
you can do one of many things.

1. There is a setting that allows you (on the printer) to decide what
input to use. But the fault to that is you can't just have it pick a
signal that you wish it to receive information from, you have to
manually change it every time.(So I put that as your worst option)

2. Your second option is to use what's called a A/B switch box. You
can also get an A/B/C/D switch box. EXAMPLE:
http://www.cablesnmor.com/parallel-switch.html
 This is a box that you connect one (preferably parallel cable to) to
this box and would then have cables that would separately connect to
every other computer. This way when you turn the switch on A you
connect to one workstation. Then when you switch it to B it would
connect to another. (The thing that makes this difficult is the manual
activity of switching the box to the proper computer to print)

3. Thirdly and what I think is best is a 10BT print server. This is an
example of a print server component. EXAMPLE:
http://www.bizrate.com/marketplace/product_info/details__cat_id--497,prod_id--5158358.html
With this you would simply connect your parallel cable to this print
server and then connect this print server to your router or hub. The
instructions would allow you to configure it so that you can connect
to the printer either with windows or UNIX on a local network. The
component will save you time money and the additional ability to
connect as many computers that are on that network to it.

4. Fourth and most difficult is to make a shared printer, which is to
connect one computer and its printer into a network and allow other
computers to connect to it in order to print. First you have to
constantly leave that computer on which may be ok for whatever else
you may use it for. Second you have to do what configuration is
necessary to allow other computers to contact that ones ?shared
printer?. Depending on the OS this may become difficult as well as
becoming a security issue. ( I would recommend this if you have time
to get into an area of computer networking that can become a little
difficult. However there is plenty of material online to assist you in
your endeavors)
