| Can we have a little clarification here please, folks? What exactly
are you asking for?
It might just be worth explaining a few things about the way in
which different laser printer file types (.POST, .LN03, .anything_else)
are dealt with before rushing off and putting restrictions in place.
Firstly, the LN03 printer is (obviously) a *lot* slower than the
LPS40 (nominal 8 pages/minute as opposed to nominal 40 pages/minute).
You do not *have* to queue LN03 files to the LN03 printer - they
can be printed just as successfully (and more quickly) on the LPS40
by sending them to the queue ANSI_EYE (print/queue=ansi_eye).
Secondly, .LN03 files in general will appear to be a lot bigger
than .POST files for the same amount of printable data. This is
because the .LN03 file contains its own font information. Postscript
files specify (internally) the font that they require, which then
has to be loaded from another VAX (known as the LPS40 Host System).
Thus, if you take two (say 70 block) files - one .LN03, and one
.POST, the .LN03 file will end up printing about 10 lines of text,
but the .POST file will print several pages. These figures are not
accurate, but they illustrate the difference.
.TXT (and the like) files tend to print more quickly as they use
a monospaced font (and do not have to swap fonts while printing
such things as titles, headings etc). However, you should be aware
that existance of (even just a single) escape sequence in a .TXT
file will slow down its printing dramatically as it causes the LPS40
to go into a spin while it checks to see if a font change is/is
not required.
As it is not currently possible to restrict entries in a specific
queue to a particular file extension, I hope you can see from the
above that putting a clamp on a queue in such a way that it operates
fairly is not an easy matter. It's simple enough with impact printers
(LP25 etc) as they will only handle one type of file, but laser
printers present a rather more difficult problem. Far better, I
would think for people to act in a sensible manner and use their
judgement. When all is said and done, you can use the /AFTER= switch
if you don't want to clog the queue right at this moment.

| The primary input bin for the LPS40 holds about 2500 A4 sheets max.
There is a secondary input bin for A4 paper holding about 500 sheets
(could be used for slides?), and another A3 input bin also of about
500 sheets.
As regards the 200 blocks, its difficult to say (depends on fonts,
graphics etc). For plain ascii text file however, it would be something
like:
1 block = 512 bytes = 512 characters
200 blocks = 200 x 512 characters = 102400 characters
102400 characters = 102400/80 characters per line = 1280 lines
1280 lines = 1280/66 lines per page = 20 pages
