With my NEC-P6 it has happened once in the Letter Quality mode, that it has inserted a vertical skip. This can be avoided with a reduction of the horizontal offset (<#136#>-h<#136#> option). I have not been able to locate the cause of the error.
Now and then, the frequency depending on what type of printer you use, it occurs that the operating system displays a requester with ``Printer-Trouble'' and that the printer does not get any more data. After clicking on the RETRY gadget, the printer resumes printing without any problems. In case the requester appears more often, reducing the printer buffer with the <#137#>-e<#137#> option usually helps to eliminate these disturbances.
I have not experienced other errors as yet. Should you find one however, please send it to me in a reproducable form (with log- and DVI file).
