Re: RedHat 5.1 CUPS problems

Not that I do printers often, but

(1) are you using a CUPS supplied drivers or HP's driver/PPD file, or your
own PPD.

For text output, you can write your own PPD. HP PPD information is fairly
easy to find; IIRC, googling "ppd" & "HP" or the such brought up a lot of
information.

(2) your description could be a font translation problem: document to HP
built-in fonts.
It could also be a page definition error: the margins are different 1" on
one and 1.25" on the other. The printable area value or the margins appear
to be different.
It appears that your current driver/ppd has an automatically linefeed after
paragraphs.
It could something else entirely.
It could be a combination.

It all this, be thankfully that you are dealing with an HP printer. Xerox
has VERY little information on their printer (that we used) and it was a
bear to get things right (the printers in question were 3 suites down and
the Oracle Financials consultant didn't understand what information I
needed--it was all trial error on my part).


Personally, I almost always use the generic/laser printer/postscript for
CUPS and have never had a problem.

For HP printers, you can start with the original laserjet driver. If it
works, you can go through the HP drivers/PPDs until it breaks. (Or until it
starts working.)

We are trying to upgrade from Red Hat Enterprise 3 to Red Hat Enterprise
5.1 and everything was going great until we tried to print with CUPS. We
have both the old and new Red Hat servers networked into the same HP4250
LaserJet. Our applications are identical on both systems. When we try to
print a portrait form with CUPS 1.1 on the old Server, it prints fine. But,
when we try to print the same form on the new server with CUPS 1.2, the
lines start wrapping at about column 71. Also, forms that contain both
CR+LF print double spaced under CUPS 1.2, but they print fine under CUPS
1.1.

We have compared the actual print file from both servers, and they are the
same, so obviously CUPS is acting differently.

We are setup for 6lpi and 12cpi. For 3 days we have been changing
settings, but nothing seems to help. Can anyone help?

Thanks,
