Trouble printing PDF documents with Acrobat Reader 7.0

[Zoe]

Hello everyone,

now and then I experience when printing PDF documents with Acrobat Reader 7.0 comical effects:

The PDF on the screen looks quite normal, but when pressure is nonsense. It seems to me that the pressure of the lowest bit number is changed, then the leaf is as full of exclamation marks (ASCII code 33, instead of blank = code 32).

This problem occurs only sporadically, such as 10 to 20% of the cases on. I then printed the same (!) PDF document directly again, the expression is usually OK, in rare cases, it works only at the third attempt.

The problem occurs on two different computers at once with a blob of ink printer (USB port), and also on another computer with a parallel port on the connected laser printer. It can not therefore be subject to the hardware.

The strange error with PDF documents from various sources.

Who knows this strange effect, and what can you do?

Thank you for your tips in advance

My tip is really only for laser printers.
Many laser printers have multiple page description languages (PostScript, PCL in different versions, etc.), and emulation.
If the file was created improper hooks sometimes autodetection. Then only helps the printer to a mode and to print.

Other versions do the same?

The whole looks like a bug from an uninitialized variable.
For the Adobe Acrobat Reader 7, there were several updates:

Hmm ... still a very silly idea:
The BIOS detects the CPU correctly, or is it "unknown CPU"?

Hello,

Thank you both for your replies. Unfortunately, both answers to solve the problem.

1. The error also occurs in several spotlights on ink (Canon and HP), not only in the HP laser.

2. Importing the update also does not help.

My hope is that someone KNOWS this error and perhaps even did somewhat successfully.
