Before I start, I know this isn't a Samba-related issue but it seems to be a widespread enough problem that someone else may have figured out a Samba-oriented workaround, or any other solution for that matter.
Hi, Steve,
not that I am sure about a solution. But I know about a similar problem with HP PS printers, if you use a particular setting of the HP-provided PPD file (part of the driver, as used f.e. by CUPS, but also by Windows clients). Since you are asking on the Samba list, I assume your Windows clients use the PS driver for the PDF files. v(PCL drivers on PDF files are dead-slow in any case).
The drivers contain a setting called "Scale Patterns". These should be set to "Off", because the "On" is very buggy and may crash the printer.
There seems to be a problem with certain models of HP Laserjet (including, but not limited, to the 4000 series and other models from the same era - it is apparently fixed in the 4100). Certain PDF files, when printed, cause the printer to crash - although outwardly it appears to be processing the job (data light flashing and so on), nothing ever happens until you reset the printer and delete the job. Resending it will cause it to crash again.
I've asked around and it's not just us who suffer - I know of several other people with exactly the same problem, and all use different systems - we use Samba, another uses Windows Server and yet another just uses peer-to-peer with no server at all. The best help I've found on HP's support site is an article saying it happens on Apple Macs and is related to a certain font.
Which font?
Is it a font enumerated in the PPD? (In that case it may help to edit the PPD and delete that font from the list....)
No mention of it happening on Windows, but it does and is clearly a cross platform problem. The workarounds suggested are to either edit the PDF file and remove the offending font, or to print as an image. The latter works, but is incredibly slow (a couple of minutes per page) for even the simplest of documents.
The printer I have most problems with is in a student computer room, and at times I have to go back and forth to power cycle the printer several times an hour. I also can't rely on the students following fairly complicated instructions to get round it - experience shows they just click print half a dozen times before giving up, leaving the print queue clogged up with corrupt jobs.
So, does anyone have any suggested workarounds? Has anyone else actually seen this problem? I'm using Samba under Gentoo Linux on the server, LPRNG as my printing system and Windows 2000 on the workstations.
Thanks in advance.
Steve.
