I just downloaded the GS22.EXE Ghostscript port from the SIMTEL archive. Using a VGA monitor, everything works well (considering I haven't gotten the font files yet). However, when I try to print to my Epson LQ-1050 (-sDEVICE=epson), the resulting image is distorted. On some lines, the print head doesn't travel as far, leaving a ragged right border and shifting part of the picture with it. It looks like information is being lost within areas of totally white space (i.e. no pins firing), and at least somewhat proportionately to the amount of whitespace in the line. This distinction is especially visible when printing the golfer.ps file. Is there a "fencepost" error in the Epson driver while printing whitespace, or is my case unique? The printer prints bidirectionally by default; I did try to "prime" it first with a command to put it in Unidirectional mode, but apparently the internal Epson driver in GS22 undoes this setting. I can't see any difference between adjacent lines based on the direction of travel, though. I have also tried removing all TSR's, with no effect. In case it matters: The system is a 25-MHz 386 (Easy Data), with the printer parallel port (LPT1:) on an Everex multi-I/O card.

I've now tried it also on a Compaq 286 connected to an LQ-850, with identical results. Both printers are 24-pin; the 1050 is just the wide-carriage model. -- Brian Marley, National Semiconductor Corp. brian@nsc.nsc.com (408)721-3918 {sun | decwrl | pyramid | hplabs} ! nsc ! brian

I have a Fujitsu DL1100. Its emulations include Epson LQ2550. I was running Quattro Pro 1.0 and told it my printer was an Apple Laserwriter Plus for postscript output, then redirected the print to a file. The results were the same as described above. Tabs were inaccurate; vertical feeds were wrong, etc. I then restarted Quattro Pro and told it the printer was a generic postscript printer. I then got a beautiful output. Strangely, both files produced correct output to the screen device. It sounds like the change-in-ESC-codes hypothesis may be correct. Anyhow, for those who do not want to recompile GS themselves, this may be a workaround. (BTW, golfer.ps prints fine on my printer. Didn't someone say they had problems with this one?) -- --Jeff Hartung-- Disclaimer: My opinions only, etc., etc., BLAH! BLAH! BLAH!...
